Sigma releases interchangeable lens compatibility notes for Nikon Z7 and Canon EOS R

27 Oct

Sigma has released compatibility notes for its interchangeable lenses when used with the Canon EOS R and Mount Adapter EF-EOS R, as well as updated compatibility information related to the Nikon Z7. The updates follow Sigma’s compatibility note for the Nikon Z7 released in late September, during which time the company said it would continue testing products and publishing future updates.

According to the company, its interchangeable lenses for Canon mount “do not have any issues with general operation” when used with the Canon EOS R and EF-EOS R adapter. However, users will need to disable the in-camera Digital Lens Optimizer feature before using a Sigma interchangeable lens with the model.

Sigma states:

When the Digital Lens Optimizer is switched [OFF], but “Peripheral illumination correction”, “Chromatic aberration correction” and “Distortion correction”, located within the in-camera Lens Aberration Correction function is switched [ON], the appropriate corrections can be achieved in accordance with the optical characteristics of each lens. This is applicable to lenses listed below which were released after March, 2018, or those of which firmware has been updated to Ver.2.0 or later.

In regards to its updated Nikon Z7 compatibility data, Sigma has released a list of 36 interchangeable lenses for Nikon mount that it tested and found compatible with the Nikon Z7 and Mount Adapter FTZ. When used together, “both AF and AE operate without any issue,” the company stated in its latest release.

The full list of compatible lenses is available in the press release below:

The essential pro feature that no mirrorless camera offers

27 Oct

In a low-light situation with a split-second to focus and capture the moment, the flashgun’s AF illuminator was essential. Mirrorless cameras tend not to offer this feature and their AF systems aren’t so good in low light that they don’t need it.

Mirrorless cameras have caught up with DSLRs in almost every measurable respect, yet there’s still one feature that’s essential for some professionals that every one of them lacks: flash AF illumination.

The failure to offer an AF illuminator target means mirrorless can’t compete with the best DSLRs in some shooting situations

Wedding and event photographers in particular will recognize the benefit of the AF assist target projected by flashguns and some flash commander units, yet no mirrorless camera maker implements this feature, even on their highest-end models. There are some technical reasons why they omit the feature, but this doesn’t negate the need for it.

‘IR’ illuminators on flashguns aren’t solely emitting infra-red: they also emit visible red light, or you wouldn’t be able to see their telltale grid pattern

It won’t affect everybody’s day-to-day photography, but the universal failure to offer some sort of AF illuminator target for mirrorless cameras remains a major shortcoming and means mirrorless can’t compete with the best DSLRs in some shooting situations.

There are technical justifications for why they don’t: DSLR autofocus sensors can be sensitive to infra-red light, whereas mirrorless cameras aren’t. Because mirrorless cameras focus using their main imaging sensor, any IR has to be filtered-out to avoid skewing the colors in your images. But the AF illuminators on flashguns aren’t solely emitting infra-red: they also emit lots of visible red light, otherwise you wouldn’t be able to see the telltale red grid they project.

Note that the ‘IR’ illuminator in this instance is projecting a visible red target and, crucially, a target that provides a pattern for the camera’s AF system to bite onto.

Another complication is that phase-detection pixels live behind the colored filters that allow most cameras to interpret color in the scene, so may not even see any red light. A PDAF element behind a blue filter won’t see any red light and one behind a green filter will only see a very small amount. But even this shouldn’t be insurmountable: Canon’s Dual Pixel AF means every pixel (including the red-sensitive ones) is a PDAF pixel and, if it came down to it, the manufacturers could offer versions of their flashguns that emit a color that their mirrorless AF systems can see.

If mirrorless cameras are going to displace DSLRs for wedding and event photography, manufacturers need to find a way

Most mirrorless cameras have their own built-in AF illuminators but they’re not nearly as powerful as the off-board lamps on flashguns. Also, they tend to be bright, uniform orange or green lamps which are visually distracting, easily blocked by hands or large lenses and which miss one of the key properties of off-board illuminators: a grid pattern. This grid pattern effectively creates some hard-edges for the AF system to bite onto, even if you’re shooting something that may not have enough inherent contrast to easily focus on. You know, like a white wedding dress in low light.

If mirrorless cameras are going to displace DSLRs for wedding and event photography, manufacturers need to find a way, even if it involves selling (or modifying) flash units that emit a faint green or blue grid pattern. Or doing what Godox does with its X1T command units: firing its red target, just as it would for DSLRs, because in many cases this is better than nothing.

Venus Optics announces Laowa 10-18mm F4.5-5.6 FE lens, RF & Z mount versions “coming soon”

26 Oct

Venus Optics has announced the Laowa 10-18mm F4.5-5.6 FE zoom lens, a new ultra-wide-angle manual lens for full-frame Sony cameras.

“In response to the demand from mirrorless camera shooters of having a compact wide angle zoom, Venus Optics [has] managed to compress the size of the 10-18mm FE Zoom to the smallest in its class,” reads the press release. The lens measures in at 3.5in/9cm long, 2.75in/70mm in diameter, and weighs only 17.5oz/496g.

It’s constructed of 14 elements in 10 groups, including two aspherical elements and one extra-low dispersion element. The lens has a minimum focusing distance of 6in/15cm and a minimum aperture of F22 with a five-blade aperture diaphragm.

The rear of the lens has a 37mm filter thread for adding filters to, as well as a 100mm magnetic filter holder system for the front of the lens. A built-in switch de-clicks the aperture on-demand if you’re planning on using the lens for video shooting.

Venus Optics has shared a gallery of sample images captured with the lens on Flickr.

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_4715342473″,”galleryId”:”4715342473″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The lens is currently available for pre-order for $ 849. The first 50 pre-orders through Laowa’s site will receive a free 100mm magnetic filter holder system.

Venus Optics says a Canon RF- and Nikon Z-mount version of the lens will be “coming soon.”

Insight Investment Astronomy Photographer of the Year 2018 winners

The Royal Observatory Greenwich has announced the winners of its annual astronomy photo competition. American photographer Brad Goldpaint’s Transport the Soul, a dreamy photo of the Milky Way and Andromeda galaxy hanging over Moab, Utah, took the People and Space category’s top prize and was named Overall Winner. A total of 31 winning images were selected across 11 categories – take a look at them here and visit Royal Observatory Greenwich’s site to get yourself ready for next year’s competition.

Transport the Soul © Brad Goldpaint (USA) – WINNER (PEOPLE AND SPACE) AND OVERALL WINNER
Interested in adding a ‘human element’ to his photographs, once the quarter moon rose and revealed the incredible, vast landscape of the shale hills below the viewpoint, the lone photographer, to the left of the frame, stood motionless while he captured this photograph. The Andromeda Galaxy, quarter moon, Milky Way Galaxy, and position of the photographer all combined to create a captivating, harmonious portrait of a night sky photographer at work.

PEOPLE AND SPACE: Living Space © Andrew Whyte (UK) – RUNNER-UP
This is a single-frame image and not a speculative composite. Situated on a south-coast peninsula, this street falls within a part-night street lighting zone; when the lights go out, there’s nothing to interfere with the view of the stars until continental Europe- miles across the English Channel. The scene might be perceived incongruous or surreal and almost shows how accustomed we’ve become to the loss of night sky views due to light pollution. It was a conscious decision by the photographer to feature the unlit streetlamps, hinting how it might be possible to undo the damage and restore awe-inspiring views.

OUR MOON: Inverted Colours of the boundary between Mare Serenitatis and Mare Tranquilitatis © Jordi Delpeix Borrell (Spain) – WINNER
Inverting the image is a legacy of deep sky imaging, where tenuous extensions of galaxies and nebulae can be more visible on a negative image because our eye more easily detects tenuous dark details on a white background. This is also useful in Moon imaging helping to reveal otherwise barely detectable soil features such as ray systems. Low contrast areas like the lunar seas and ray systems, look much more interesting because low contrast details are revealed and according to the photographer this is a new way for Moon exploration that should be considered.

OUR MOON: From the Dark Side © László Francsics (Hungary) – HIGHLY COMMENDED
The photographer had planned to capture a high resolution image of the morning crescent Moon for a long time. The waning crescent Moon only rises high above the horizon of the Carpathian basin in autumn, but in this period of the year the weather is usually cloudy and rainy. Fortunately, in October 2017, an anticyclone wiped the area clear, which allowed the photographer to take a good resolution picture capturing the special atmosphere of the thin crescent in a glitteringly bright sky.

OUR SUN: Sun King, Little King, and God of War © Nicolas Lefaudeux (France) – WINNER
In order to capture this mesmerising image, the photographer chose the area according to weather forecasts to make sure he would get a clear sky. The image shows the Sun corona in all its glory during the August total solar eclipse. It is flanked on left hand side by the blue star Regulus – the little King – and by the red planet Mars on the right. The many radial streamers of the solar Corona are a real crown for the Sun King and the corona can be traced almost to 30 solar radii distance. The total exposure duration of 100-seconds was recorded in more than 120 individual images and it is a setup consisting of both a fast f/1.4 lens, at full aperture to get as much signal as possible, and a large buffer camera at base ISO to avoid overexposure. The inner corona was recorded using a longer focal length setup.

In this image the photographer managed to capture an eruptive prominence just hours after this active region produced a massive X9.0 class solar flare. Close to the solar limb and presented here in an inverted format (black to white) and colour enhanced to create a warm sunny glow, the photograph showcases the beautiful 3D structure within the hydrogen chromosphere. Captured in hydrogen alpha light at 656.3nm, the photographer used a 150mm solar telescope and monochrome machine vision camera to record a video sequence which was stacked to bring out the fine details and image processing techniques to produce colour and a backlit effect in order to enhance the spicule features around the solar limb.

PLANETS, COMETS AND ASTEROIDS: The Grace of Venus © Martin Lewis (UK) – WINNER
Shortly before sunset, a slender and graceful Venus hangs low in the western sky, just 10 days before meeting the Sun at inferior conjunction. This is an infra-red image of that view, taken using a monochrome digital video camera mounted on a reflector telescope. The recording was processed to remove the blurring effects of our atmosphere and combine the video frames to create a single still image of the planet. The infra-red filter used on the camera helps steady the effects of atmospheric movement.

PLANETS, COMETS AND ASTEROIDS: Parade of the Planets © Martin Lewis (UK) – RUNNER-UP
During the course of just one year the photographer managed to image surface details on every planet in our Solar System from his own back garden. At the start of the year, the photographer had captured distant Mars, eight months after opposition, sporting a tiny polar cap and dark features. Later on, he captured Venus, then Jupiter and Saturn. In September, the photographer had imaged details on the rocky face of Mercury for the first time and in November he recorded Uranus’s distinct polar region, making the set complete. The more challenging planets, Mercury, Uranus and Neptune, required IR (infrared) imaging to bring out surface details and have been colourised to match their more normal visual appearance. All images are displayed at the same relative size that they would appear through a telescope.

PLANETS, COMETS AND ASTEROIDS: Comet C/2016 R2 Panstarrs the blue carbon monoxide comet © Gerald Rhemann (Austria) – HIGHLY COMMENDED
Still relatively far from the Sun, the comet’s well-developed ion tail shines bright in the night sky. Emission from unusually abundant ionized carbon monoxide (CO+) molecules fluorescing in the increasing sunlight is largely responsible for the beautiful blue tint. This is a median stack of the total event from 5p.m. until 11.12p.m and the comet’s magnitude was approx. 12.5 mag.

SKYSCAPES: Eclipsed Moon Trail © Chuanjin Su (China) – RUNNER-UP
On 31 January 2018, a spectacular total lunar eclipse occurred. The photographer set his camera for a four-hour stack exposure and after he took about one thousand images, he finally captured an image that reflects the changes of the Moon’s colour and brightness before, during and after the eclipse. The picture reminded the photographer of the Compliant Golden-Hooped Rod, which is the weapon of the Monkey King, who is described in ancient Chinese literature.

STARS AND NEBULAE: Thackeray’s Globules in Narrowband Colour © Rolf Wahl Olsen (Denmark) – HIGHLY COMMENDED
Almost 5,900 light years away, toward the southern constellation Centaurus, lies a large beautiful nebula known as the Lambda Centauri Nebula. The intense light from stars in a young open cluster cause the surrounding gas to glow with a magenta hue from emission lines of ionised Hydrogen atoms. In the centre of the image, is a group of Bok globules, which are dark, dense collapsing patches of gas and dust where new stars are frequently born. These were discovered by South African astronomer, A. David Thackeray, in 1950 and are now known as Thackeray’s Globules and are a favourite target for backyard astrophotographers. The largest globule is two separate clouds that overlap slightly. While they appear small in the context of the grand nebula, these overlapping globules are each 1.4 light years across and together they contain more than 15 times the mass of our Sun.

1000-year long exposure due to reveal effects of climate change for exhibition in 3018

26 Oct
The view from Eagle Rock – a digital pinhole image by Ryland West, showing the view from one of Keat’s camera sites

A series of pinhole cameras have been positioned around Lake Tahoe to record in a single exposure the effects of climate change over the course of the next 1000 years. Conceptual artist Jonathon Keats has booked space at the nearby Sierra Nevada College to hold an exhibition of the results in the year 3018.

The idea of the project is to show the long-term effects of climate change on the environment, by recording how the scenes the four cameras are pointed at alter over the course of a 1000-year exposure. Though technical details are scant regarding the size of the aperture, the basic premise of the cameras is a pinhole construction with a rose-colored pigment to record the image. The pinholes have been made in 24-karat gold sheets (though the reason isn’t clear why gold was used) and the pigment records the image by fading in areas where it is exposed to most light. As it is the areas that are exposed to light that fade the final image will be positive.

According to an interview on the Vice’s Motherboard website Keats has ‘borrowed a technique from Renaissance painters who worked with copper. This involved rubbing the copper with pumice stone, then rubbing it with garlic and finally applying a layer of pigment. After studying different pigments, Keats chose rose madder, a red pigment that is derived from the root of a madder plant.’

The tiny cameras have a copper body and measure 2.75in long by 2.25in in diameter, and have been placed in strategic positions to monitor the condition of the lake and its shoreline. Whether the cameras can remain still for 1000 years, and whether the exposure will be right in 3018, remains to be seen – but not by any of us. Keats himself says in the Motherboard interview “The [environmental] changes that happen may wipe out the camera or wipe out the institution that’s in charge of it. I just signed a contract with Sierra Nevada College that is for an exhibition of these four photographs in the year 3018. We’re certainly taking chances with this, but that’s also part of the picture in a way.”
I’ll wait closer; to the time before buying a ticket for the opening night.

Press release

TAHOE TIMESCAPE VISUALIZE LAKE TAHOE IN 3018

Experimental Philosopher Jonathon Keats Explores 1,000 Years of Environmental Change in the Lake Tahoe Basin

TAHOE PUBLIC ART INSTALLATION | 2018 – 3018
ART EXHIBITION | OCT 18 – NOV 16, 2018
TAHOE GALLERY, SNC, Incline Village, NV

Tahoe Timescape is a public art project conceptualized by experimental philosopher and artist Jonathon Keats that photographically documents the next thousand years of environmental change in the Lake Tahoe Basin. The project enlists a new approach to photography based on the traditional pinhole camera. Pierced through a plate of 24-karat gold, a minuscule pinhole focuses light onto a rose colored pigment, such that the color fades most where the light is brightest, very slowly imprinting a unique positive image. The Millennium Camera’s thousand-year-long photographic exposure, taken between 2018 – 3018, not only shows the view in front of the camera, but also records how it develops over time, revealing dynamics ranging from urban development to climate change.

Digital Pinhole Photograph from Eagle Rock | Site Photography by Ryland West
While one goal of Tahoe Timescape is to provide documentation of human and environmental dynamics for study by future generations, the Millennium Camera, custom made from copper for durability, is equally intended as a mechanism for people today to envision their long-term impact on the environment – and potentially to change the picture by altering their behavior.

Tahoe Timescape features four Millennium Cameras that will be deployed around all four shores of Lake Tahoe, with fixed vantage points positioned to provide an expansive view of the Lake Tahoe Basin, presenting multiple opportunities for the public to engage in deep-time thinking as they explore the region. The copper brackets that secure each camera in their location, as well as informative plaques mounted next to the cameras, are fabricated locally by Mountain Forge. The four locations, pinpointed on a topographic map and identified by geographic coordinates, are as follows:

  • South Shore: Heavenly Mountain Resort, South Lake Tahoe, NV / CA
  • West Shore: Eagle Rock, Homewood, CA
  • North Shore: Lake Tahoe Dam, Tahoe City, CA
  • East Shore: Sand Harbor, NV

Jonathon Keats and Tahoe Public Art’s Executive Director, Mia Hanak, conducted site surveys to identify the vantage points and Millennium Camera locations. Local landscape photographer Ryland West explored each site to shoot a set of landscape photographs paired with digital pinhole photographs focused on the actual vantage point from the Millennium Cameras to help us imagine the photographic composition that will be recorded by each between now and 3018.

“Tahoe Public Art is truly excited to be presenting the conceptual art of Jonathon Keats to the Lake Tahoe Basin. With the ongoing stewardship of Sierra Nevada College, we hope this encourages tourists and residents alike to contemplate the future of the basin and how they can become active in its preservation.” – Steve Miller, Chairman, Tahoe Public Art.

Further outreach will be facilitated by an exhibition about deep time photography at Sierra Nevada College’s Tahoe Gallery. Opening on October 18th and running through November 16 in 2018, the exhibition will feature four sets of landscape photographs, digital medium format pinhole photographs, and photo documentation of the cameras secured at each location. Samplings of pinhole cameras, and a topographic map showing the camera sites and geographic coordinates will also be showcased. On September 5th, Keats led a pinhole camera workshop for SNC students. The exhibition will also showcase original artwork by SNC students — including 2-D, 3-D, digital arts, and interdisciplinary art — encapsulating how they envision Lake Tahoe in one thousand years.

Side-by-side Comparisons of Basic Studio Light Modifiers

Side-by-side Comparisons of Basic Studio Light Modifiers 1

Have you ever wondered what difference studio light modifiers make to your portraits?

Are you even convinced that they make a difference in the quality of light? I thought I’d do a little experiment to show you the effects that a few basic studio light modifiers can have on your portraits.

For some, the right modifier may make an image great, and the wrong modifier could break it.

Technical terms

Firstly, if you are new to artificial lighting, let’s look at some technical terms.

Flash – an electronic artificial light source which gives out a brief, sudden burst of light. A flash is also known as a strobe in North America.

Reflector – a panel that bounces light back towards the source and comes in silver, gold, black, white, fabric or other material.

Light modifier – an object attached to the front of the flash to change the quality and effect of light entering the camera.

Shoot – through Umbrella – an umbrella made of translucent fabric that allows light to pass through it.

Diffusion – a material that scatters light evenly as it passes through, thereby making the light softer and with less glare and harshness.

Softbox – a closed chamber usually lined in white or silver fabric, available in various shapes (such as a square, rectangle, umbrella, octagon). A softbox confines the light from the flash and releases it through a diffusion material, thereby allowing more control as to the size and spread of light that reaches your subject.

Grid – usually made from fabric strips of material that are sewn together to form a 3D grid that is attached to the light modifier. A grid restricts the focus of light, making it more directional, allowing the photographer more control. It also limits or restricts the spill of light onto other areas.

The studio light modifiers used in this article

Let’s start with the lighting diagram as shown below. My set-up consisted of 2 lights and the following:

Side-by-side Comparisons of Basic Studio Light Modifiers 2

  • a dark wall
  • a large silver panel reflector on camera left
  • a flash high up on the camera left to give a bit of hair light – I wasn’t after a vast separation from the background as I was using a light colored sofa that separates the background and the subject already. I also wanted a rather dark, moody lighting, so I covered the flash with a few layers of diffuser fabric. Doing this cut light out and limited it to the subject rather than hitting the wall
  • a flash on camera right onto which I attached various modifiers
  • studio light modifiers: flash hood, translucent umbrella, umbrella softbox, 90 x 60 softbox, diffuser fabric, grid

You can also shoot with one light, of course, see here for a beginner’s tutorial on how to create dramatic portraits with one light.

Side-by-side Comparisons of Basic Studio Light Modifiers 3

Left: #1 Shoot-through umbrella facing away. Right: #2 Shoot-through umbrella facing toward.

#1 Shoot-through umbrella facing away from subject

For the above-left image, I used an umbrella as a shoot through with the flash facing away from the subject. You can see there is still light hitting the subject’s face, but the shadows on the left side of the face and the neck are a lot more pronounced and harsh. The light was not able to reach the reflector to the left of the subject at all.

#2 Shoot-through umbrella facing toward subject

Compare this with the image on the right. I turned the flash and umbrella 180 degrees so that the flash was facing the subject and shot from behind the umbrella. The shadows are much softer, more light has reached the subject, and you can also see the light hitting the sofa on the far left which means the reflector was doing its job of bouncing some light back.

Side-by-side Comparisons of Basic Studio Light Modifiers 4

Left: #3 Bare flash with hood. Right: #4 Umbrella softbox

#3 Bare flash with hood

For the above-left image, I shot using just the electronic flash and the hood that comes with it. As it is rather small, it restricts the spread of light a little and focuses it more on the area you are lighting.

The light spills only as the light leaves the hood. Shadows on the face here are still defined, and not as smooth as I’d like it, but it is much better than on #1, where the shadows are much darker and harsher.

#4 Umbrella softbox

In the above-right image, I used a deep umbrella softbox allowing me to face both the flash and umbrella away from my subject. The umbrella is silver-lined which bounces all the light back towards the subject through a diffuser fabric. The resulting light quality is softer and more evenly spread due to bouncing and diffusion.

Compare this to image #2 that used only the shoot-through umbrella without the bounce. Notice how the light quality is gentler on the skin and more evenly spread, with softer shadows on the neck and under the nose.

Side-by-side Comparisons of Basic Studio Light Modifiers 5

Left: #5 Softbox Without the Diffusion Panel. Right: #6 Softbox with diffusion panel.

#5 Softbox without the diffusion panel

I switched to a 90 x 60 rectangular softbox for the images above. The one on the left is an example without the diffusion panel that covers the softbox. Shooting your subject without the diffusion panel is like shooting with a hood, as per example #3 (the hood also has a silver lining), only the softbox is larger.

The light is flashed away from the subject onto the silver lining of the softbox and bounced from the silver lining towards the subject without having to go through a diffusion panel.

#6 Softbox with diffusion panel

Comparing both images above, do you notice the softer quality of the light on the subject’s face on the image with the diffusion ‘on’? It is a subtle difference, but I can see it. Look even closer and you see the light without the diffusion is cooler and slightly harsher. It comes directly from the silver lining of the softbox not having gone through any diffusion.

This difference is noticeable on the sofa; the one on the left is a touch sharper and the one on the right darker and even. Compare the subject’s left eye (on camera right) – the shadow on the left image is stronger and deeper than the one on the right.

Such is the modifying effect of even just one diffuser fabric!

Side-by-side Comparisons of Basic Studio Light Modifiers 6

Left: #7 Softbox with the grid. Right: #8 Gridded softbox with the power adjusted.

#7 Softbox with grid

I attached a grid to the light set-up above so that it’s a silver-lined softbox with a diffusion panel plus a grid attached on the front of the diffusion panel. This setup is called a gridded softbox.

Notice just how much of the light has been cut out. Light gets focused on the face, and there are very few spills of light on the clothes, arms and outer areas of the space photographed.

The resulting image is a lot darker, moodier, and warmer in tone. However, I feel this is too underexposed, and details on the dress get lost, when I wanted these to show. The green wall looked too black, and the dress seemed to blend too much into it.

#8 Gridded softbox with power adjusted

On the above-right image, I kept the gridded softbox on and adjusted the flash power to my liking in order bring back the details I wanted. This new flash setting illuminated the face more and brought highlights back onto the hair and eyes. It also allowed a touch of light on the background too.

Finally, the end product I had in my mind used a textured background, so I added this texture to my dark green wall in Photoshop. For a step-by-step guide on how to add textures and creative overlays, see this post. In my opinion, the subtle texture adds more drama to the image and fits in better with the dark and moody lighting I was after.

Real Estate Photography: Get Better Results with the Right Equipment

25 Oct

Real estate photography throws many challenges your way, just like any type of photography.

You deal with perspective issues and light and shadow extremes that confound even the best cameras. You also need to be critically aware of your surroundings and probably have very limited time to do the job.

The good news is, creating pleasing photos of interior rooms no longer requires a great deal of investment and experience. Nowadays, it only requires a few specific items, a few pointers, and a little practice.

In this article, you’ll learn how to get better results with the right equipment to take your real estate photography to the next level.

Which camera to choose for Real Estate Photography

Smart Phones

While the main choices for real estate photography are between DSLR or mirrorless cameras, you may hear an argument in favor of modern smartphones too.

While smartphone cameras are useful for some scenarios, they are not well suited to real estate photography.

Some of the main downfalls of smartphones include:

  • Smartphone Apps process the image for you, resulting in a processed JPG image that you have little or no control over. The ‘lossy’ nature of JPG discards much of the original information, limiting what you can do in post-processing.
  • The sensors are tiny, with the pixels packed in tight, reducing the dynamic range and causing more noise.
  • Lenses are tiny and generally made of plastic. They lack the precision of milled glass lenses, and are easily scuffed or scratched. Lens quality plays a big part in achieving good quality images, so it’s unrealistic to expect the same performance that you’d get from a camera lens.

Smartphones perform well under ideal lighting conditions; however, interior real estate photography presents some of the most challenging light you’ll find in photography.

Use your smartphone as a tool to find great compositional angles, but not as your main photographic equipment.

DSLR and Mirrorless Cameras

Whether your preference is a DSLR or mirrorless camera, your primary choice is format: Full Frame, Crop-sensor or Micro 4/3.

Each format changes the field of view (FOV) of a given lens. You can think of the FOV as the ‘zoom’ of the lens.

Full-frame equates to the standard 35mm film view of analog cameras and is the standard measurement still used today.

Crop-sensor cameras have smaller sensors, creating a ‘zoom’ effect of 1.5X or 1.6X. Micro four-thirds (M4/3) cameras increase the ‘zoom’ by 2X.

In practical terms, a 50mm lens on a full frame camera produces almost the same field of view as a 35mm lens on a crop-sensor camera. That same field of view results from a 25mm lens on a Micro 3/4 camera.

It’s vital to understand that different sensor sizes impact the focal length of a lens.

When reading advice on which lens to use, always remind yourself it’s the ‘equivalent’ focal length, then do the calculations as described above for your own camera’s sensor size.

The good news is that if you already own a recent model DSLR or mirrorless camera, you likely don’t need a new one.

It’s true that “recent” is a bit vague here, but in my experience, mirrorless cameras up to five years old, and DSLRs made during the last ten years should be more than capable.

Lens choices

Many photographers say prime lenses (non-zooms) produce a better quality image than zoom lenses. A good zoom lens, however, may be more convenient for real estate photography.

A decent quality zoom that starts from a wide angle (say between 12mm to 24mm) provides more compositional flexibility than a fixed lens.

Small rooms inside houses may be a little cramped, restricting the space available to set up a tripod and camera. Using a wide-angle lens of around 12-24mm may be necessary to give the required field of view to capture a small room.

In larger rooms, and when photographing outside, 35mm may give a better view of the property. There’s no definitive ‘right’ answer to field-of-view as it all depends on the surroundings and how much space you need.

If you find yourself with distorted lines and dark areas around the edge of your image shot with a wide-angle lens, these may be fixed in post-production.

Cheaper lenses, especially zooms, have more optical weaknesses, so if you’re going to invest in new gear, you might get more benefit from upgrading your lens instead of your camera body.

One indication of lens quality is a low aperture number such as f/2.8. A lower number aperture opens the lens wider than lenses with high numbers like f/5.6.

While this allows more light to enter the sensor, the focus plane becomes narrower, causing some of the room to be out of focus, which is not ideal for real estate photography. Use an aperture of f/8 or f/11 to allow more of your room to be in focus.

Chromatic aberration (CA) is caused by light dispersion as it travels through the lens. In plain English, it’s that pink/green color fringe you sometimes see around the edges of objects, most noticeably in areas of high contrast like window frames. Cheaper lenses have more problems with CA.

Using a better quality lens shows less CA, but the laws of optics means fringing can still happen occasionally. Most photo software includes functions to reduce or remove this, although it’s great to avoid it as much as possible in the first place.

Camera features to look for

Camera features to look for buried in just about every modern camera menu are the five features and functions that can seriously help for real estate photography images.

The first four of these features help you overcome the problems posed when photographing scenes with a high dynamic range (HDR). In these situations, all cameras struggle because they can’t match our eye’s adaptive responses.

The fifth, the digital level, helps with the challenge of perspective. Inside and out, houses have vertical and horizontal lines. If they’re just a little off-center, the whole photo looks lopsided and uncomfortable to the viewer.

1. AEB (Automatic Exposure Bracketing)

Automatic Exposure Bracketing is a specific setting that instructs the camera to take multiple shots of the scene while changing the shutter speed of each shot – all with one press of the shutter release button.

You can change the shutter speed for each shot manually, but it is faster (and potentially more precise) to let the camera’s onboard technology do it under your guiding hand.

2. EV Range (Exposure Value Range)

The reason to take this automatic series of shots is to capture all details, from bright windows to darker interior areas, although some cameras have more limited AEB capabilities than others.

Here are the two camera features to consider:

  • The number of bracketed shots: This is the number of exposures the camera takes when you press the shutter release in AEB mode.
  • Exposure Compensation: This is the spacing of exposure compensation between each bracketed exposure taken in AEB mode. These two factors combine to determine the total exposure range possible.

You need to look at both features to determine whether the camera’s EV range capability is sufficient for your needs. For real estate photography, look for AEB settings that let you choose five shots in 2-steps or nine shots in 1-step.

3. Continuous shooting

It is important that your camera can shoot continuously to minimize the number of times you release the shutter manually. Doing so avoids accidental camera movement or shake.

4. Luminosity histogram

The histogram offers clear information to ensure we cover the full dynamic range. While it may seem confusing at first, it’s straightforward once you know what it’s showing us.

Having an EVF (electronic viewfinder) somewhat reduces the need for a histogram but not entirely. Even with an EVF, it’s hard to determine highlight or shadow clipping by eye. Capture all the bright and dark areas correctly by using histograms.

5. Digital level

If your camera has a digital level, it’s quite handy. Not all camera models do, so you may need to look in the manual to find it. Once activated, a horizontal line runs across the scene in your viewfinder.

You can instantly see if the camera is at an angle and if so, make the needed adjustments to avoid a sloping room.

While you’re checking the horizontal lines, don’t forget the verticals. Tilting the camera up or down causes vertical lines, like walls, to look slanted.

Pro tips on using the digital level

  • Take time to inspect the scene in live view, making manual corrections if necessary even if they contradict the digital level.
  • Use a tripod so you can step away from the camera while seeing the live view screen and the room.
  • Double-check your composition for framing, height, and perspective.
  • Shoot from below eye level. An excellent place to start is between your chest and hip height, but there may be times to raise the camera. You might, for instance, want to show a particular view or other details you wish to highlight.

Flash and Lighting Equipment

Speedlights

The built-in flash on your camera is unlikely to be strong enough to balance interior and exterior light levels because of the high dynamic range present in most real estate interiors.

The built-in flash may create unwanted, deep shadows in the room. You’ll get a better effect by mounting a Speedlight flash on the hot shoe, then bouncing the light off the walls or ceilings.

With some practice, it becomes easier to find the right bounce position for each room.

Another technique for using Speedlights is taking them off camera via a wireless connection. This way, you can position the lights just where you need them.

Studio lights

Finally, there are studio lights.

While these are effective and give results that look professional, pro lighting equipment is expensive. The lights are also bulky and heavy and often need a power supply. Moreover, using them correctly requires considerable practice and skill.

The exposure bracketing technique, where you use the camera’s AEB features listed in the previous section, offers a less demanding way of achieving light balance for an interior scene.

Taking bracketed exposures becomes a natural part of your photography workflow, and you don’t have to worry about carrying heavy lighting equipment, or learning how to use it.

The bracketed exposures are then merged to HDR in post-processing to get a correctly exposed image. While Photoshop and Lightroom offer HDR merge, many real estate photographers prefer using Photomatix Pro.

This specialized HDR software offers natural-looking presets optimized for property interiors.

A tripod

If you get good, sharp results from handheld shots, using a tripod may seem unnecessary. However, no one can hold a camera steady for the slower shutter speeds used for interior real estate photography.

The minimum shutter speed for handheld shots is normally1/60 second as a rule-of-thumb, while interior scenes require much longer exposures.

What to look for in a tripod:

  • Ball heads – These let you quickly change angles and orientations without having to fiddle too much with either camera or tripod.
  • Rubber feet – When you’re working on slippery, polished floors there’s less chance of the tripod sliding out of position. Rubber feet also protect fragile surfaces.
  • Lightweight and sturdy – Look for solid construction with tight joints and rigid legs. Top-of-the-range tripods (such as carbon-fiber models) carry a higher price tag, but less expensive aluminum versions do the job equally well with a little care. Any tripod is better than no tripod at all.

A good tripod gives you more compositional freedom, as you can position them just about anywhere. Attempting to keep the camera perfectly still without a tripod limits you to existing stable surfaces.

A remote shutter release

A remote shutter release untethers you from the camera, providing freedom of movement.

While the most obvious function of the remote release is preventing camera shake when you press the shutter button, there are other, less apparent advantages too:

  • The tripod stays steady, even on a soft surface.
  • You can step aside to avoid casting shadows, or to remove your reflection from windows or shiny surfaces.
  • Your hands are free to hold distractions out of the frame, such as cables or plant fronds.
  • You can move around to assess composition from different angles or spot potential distractions.
  • You may need to monitor the road so you can shoot during a gap in traffic.

As an alternative to a remote shutter release, you can use a cable release or the camera’s automatic timer.

Some other helpful equipment

Beyond the main equipment needed for real estate photography, there are a few other items to make your job easier and more efficient:

A traditional bubble level – While the digital level is handy, some people may prefer external units that slot into the hot shoe or some tripods that have bubble levels built-in.

Gaffer tape – Use it for quick cleanups such as removing pet hair or holding back a curtain or cable. Use tape to mark the position of your tripod once you find a good composition.

Avoid using duct tape as the adhesive is too strong and it doesn’t peel off cleanly. Gaffer tape leaves no residue on most surfaces.

Cleaning cloths – You need a cloth for your lens, but also one to remove dust specks from surfaces or to polish water marks off bathroom fittings.

A lens hood – Use a short hood on your wide-angle lens to cut down the flare from windows or other bright lights.
