Adobe RGB Versus sRGB – Which Color Space Should You Be Using and Why

11 Feb

How frequently have you been to your camera settings to switch between Adobe RGB and sRGB color space? Are you even aware of what these terms mean, or what exactly is a color space? Even I was unaware of these technical terms until a few years back but I quickly realized their importance.

What is a color space?

A color space is a part of the color gamut, which is basically the universe of color tones. So you can assume different color spaces to be planets of different sizes. Out of many planets, Adobe RGB and sRGB are two most commonly used color spaces in photography.

Depending on your preferences, you can choose the desired color space and get the best possible result out of it.

What are Adobe RGB and sRGB color spaces?

Adobe RGB is a bigger color space than sRGB as it is comprised of many more variations of color tones. This is one of the reasons that Adobe RGB monitors are vastly used by photographers – they can display more colors as compared to an sRGB monitor.

Monitors and printers

Adobe RGB monitors are used by a majority of modern day printer operators as well because they are capable of showing what a CMYK (cyan magenta yellow and key or black) printer color profile can produce. This helps the printer operator to ensure that colors that are being displayed on the Adobe RGB monitor shall be very close to the print that comes out of the CMYK color space printer (used for magazines and publications).

So being a photographer it makes sense that you use an Adobe RGB monitor so that you can edit your photos and see the actual colors that will come out in the prints.

Whereas, if you are sure that you will not get your photos printed in the near future then it does not make any sense to use an Adobe RGB monitor. If you only take photos for yourself or to upload them to the web, then an sRGB monitor is ideal for your purposes.

Camera shooting color space

But in order to view the actual colors of Adobe RGB or sRGB color space on your monitor, you need to capture the photo in that particular color space in the first place.

Unless you capture a photo in the required color space, be it Adobe RGB or sRGB, you cannot use that photo to its full potential. Shooting photos in the larger Adobe RGB color space allow you to capture more color tones, thus helping you see accurate colors on Adobe RGB monitors and in the prints. Whereas clicking in sRGB color space allows you to upload images to the web without any change in colors.

While shooting in one of these two color spaces each has their own advantages, there are few disadvantages as well.

Advantages and Disadvantages of shooting in Adobe RGB


  1. You get to capture a wider range of color tones in your photos.
  2. This color space is capable of displaying color tones that come out of a CMYK printer, thus ideal color space if you print your photos.


  1. When you upload a photo captured in Adobe RGB color space on the web, the colors get desaturated (and can look “off”).
  2. Adobe RGB monitors are costly, so in order to edit Adobe RGB color space image, you need to invest a lot in a monitor.

NOTE: You can convert an Adobe RGB color profile image into sRGB color space using software such as Photoshop and Lightroom.

Left: While exporting photos in Lightroom, you get the option to choose the color space. Right: In Photoshop, you can go to Color Settings and select the required option as your working color space.

Advantages and Disadvantages of shooting in sRGB


  1. When you upload a photo shot in sRGB color space, the colors remain the same and do not get desaturated, unlike an Adobe RGB image.
  2. A majority of monitors in the world use the sRGB color space and are not that expensive, unlike Adobe RGB monitors. This ensures that the colors that you experience on your monitor would be almost the same on any other sRGB monitor.


  1. As the color tones in sRGB are less compared to Adobe RGB, you do not get accurate colors in your prints.
  2. If you submit your photos for photography contests, there are chances that those photos will be viewed on an Adobe RGB monitor. This might reduce your chances of winning as a photograph captured and edited in Adobe RGB will look more pleasing to the judges.


Adobe RGB or sRGB, which color space to choose while shooting?

If you are a photographer who prints your photos often and you want to ensure that the colors are accurate in your prints, then you must shoot in Adobe RGB color space. Shooting photos in sRGB color space might give you a variation in colors that you see on your monitor and in the final prints. Also if you participate in online photography contests, it is safe to capture and edit photos in Adobe RGB color space.

But if you only capture photos to upload them on the web, then shooting in the sRGB color space is the ideal choice for you. If you upload Adobe RGB color space photos to the web, you will notice that colors get desaturated.

Adobe RGB Versus sRGB - Which Color Space Should You Be Using and Why

Left: This is how your photo gets desaturated when you upload Adobe RGB color space photo to the web. Right: When you upload sRGB color space photos, you get correct colors as seen here.

Nonetheless, to be on the safe side you can shoot photos in the Adobe RGB color space. If needed you can always use the file for prints, and if you wish to upload to the web then you can simply convert the color space using Adobe Photoshop or Lightroom.

Interview with an astronaut: What it’s like shooting photos from space

28 Dec

Jared Polin (aka. Fro Knows Photo) recently scored an interview that has us all extremely jealous here at DPReview. A phone call to NASA to find out if astronauts shoot Raw in space led to an interview with Marine fighter pilot and NASA astronaut Randy Bresnik, who had arrived back to Earth from the International Space Station just three days before Jared spoke with him!

The entire interview is fascinating from first question to last, but first things first: yes, astronauts do shoot Raw in space. Bresnik himself says he shot RAW+JPEG so he could download the JPEGs onto his laptop and see the shots ASAP, but the Raw files are beamed down to Earth where the folks at NASA process them to their full potential.

This is far from the only only topic Polin and Bresnik cover, though. They hit everything from radiation damage, to stabilizing your shots in space, to the glass available, to what it was like switching from Nikon D4 cameras to the brand new D5s that arrived on the ISS in mid-November, and much more.

And all the while, gorgeous photos Bresnik captured while up there scroll across your screen. Photos like the ones below—some of our favorites from Bresnik’s last 2 months on the ISS:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_3868241639″,”galleryId”:”3868241639″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Editor’s Note: Bresnik also contributed the #oneworldmanyviews hashtag, which paired shots of beautiful locations captured in space with photos of the same spot taken from Earth.

For Polin, the conversation seemed surreal. He tells DPReview that:

For me I was in awe for a lot of the interview. It’s not easy to wrap your head around SPACE and the sheer fact you can transfer the data back to earth. Sure that’s been going on for decades but think about it. 250 miles up in space there’s a station with six astronauts on it, with an entire Nikon setup of D5’s and glass up to an 800 5.6 for god sake. The direct downlinks to NASA transfer data all night long.

Check out the full interview up top, scroll through the gallery above for a bit of awe, and if you want even more, head over to Bresnik’s Twitter account where you can find enough photos, videos, and timelapses to keep you busy until New Years and beyond.

And, since Polin says he may actually get to interview an astronaut who is on the space station when he talks to them, we’re curious: what would you ask an astronaut about photography in space? Drop your suggestions in the comments.

Ten Nikon D5 DSLRs will arrive at the International Space Station tomorrow

14 Nov

Back in August, NASA’s love affair with Nikon cameras made the news when the space agency ordered 53 unmodified Nikon D5 DSLRs that it would use on the International Space Station and for ‘training purposes’ here on Earth. Ten of those D5 cameras are scheduled to make it to the ISS this week.

Packed aboard the Orbital ATK OA-8 Space Station Cargo Resupply Mission that took off this Sunday at 7:19am Eastern time, and are scheduled to arrive at the ISS tomorrow morning around 4:50am (you can actually watch live coverage of the rendezvous on NASA TV starting at 3:15am).

Nikon tells us that NASA is “reusing Nikon lenses and accessories previously launch with the Nikon D4 and D2Xs cameras,” and are planning to keep the D5 cameras in circulation for 12-18 months. With any luck, the astronauts aboard the space station will use them to capture more images like these:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_9349612405″,”galleryId”:”9349612405″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

NASA’s relationship with Nikon began in 1971, when the Nikon Photomic FTN (a modified Nikon F) went to the moon with the astronauts of Apollo 15. Fast forward to 2008, and NASA ordered its first digital cameras for use in space, a set of six Nikon D2XS DSLRs, followed by an order for 11 Nikon D3S cameras in 2009, 38 Nikon D4 DSLRs in 2013, and another 10 D4s in 2016.

The only question now, I suppose, is when is the Space Agency going to replace its glass? NASA’s latest order of Nikon glass was placed in 2010, when 64 NIKKOR lenses were delivered to the space agency. If astronaut photographers are anything like us Earth-bound folk, that means they’ve been drooling over ‘better’ lenses than they currently have since about… three days after they got those lenses.

How to Use Negative Space in People Photography

11 Oct

When it comes to people photography, one of the most common pieces of advice is to “fill the frame” with your subject. In general, this is a good rule of thumb that can dramatically improve your photography right away. However, sometimes rules are meant to be broken, and learning how to use negative space in people photography can also be valuable in delivering a varied and useful gallery of images.

People Photography Negative Space

What is Negative Space?

When you’re photographing people, the subject of your image is always the person (or people) in your frame. Similarly, the negative space of an image is anything other than the subject. It’s the foreground, the background, and the visual “breathing room” all around your subject.

Although it can be counterintuitive, allowing a bit of space around your subject helps draw the viewer’s eye directly to the person you’re photographing. This, in turn, emphasizes their importance in the final image.

How to Use Negative Space in People Photography

How Do You Do Negative Space Well?

So, how do you make sure that your negative space looks intentional and not accidental when you’re photographing people? Here are a few tips that will help get you started combining negative space images and people photography.

Think in Thirds

How to Use Negative Space in People Photography

When creating a negative space image in people photography, aim for your subject to take up one-third of the image, and the negative space to take up roughly two-thirds of the image. Following guideline ensures that your subject is large enough to be seen while also creating a ratio that’s visually pleasing to the eye. You’ll also notice that using this ratio as a general framework for your images allows you to implement the rule of thirds in your negative space images, which further helps to ensure that your images are composed well and are aesthetically pleasing.

Face the Space

Rule of Thirds Photography - How to Use Negative Space in People Photography

If you elect to follow the rule of thirds and compose your subject off center, spend some time experimenting with the direction your subject is facing. Is the image stronger when your subject is facing the negative space or facing away from the negative space? As a general rule, try to pose your subject so they’re looking towards the negative space. This is particularly important if the person you’re photographing is walking, running, or playing sports.

By doing so, our brains are able to imagine the subject traveling through the negative space, which creates a more compelling and believable image. In addition, directing the person you’re photographing to look towards the negative space creates an image that looks more candid, which is a great way of adding diversity to some of your posed session images.

Bring it to the Center

How to Use Negative Space in People Photography

Keep in mind that not all negative space images have to be offset! Try bringing your subject to the center of the frame while simultaneously allowing plenty of “headspace” around them in your image. This technique is similar to the idea of white space in graphic design, rests in musical composition, and high-end clothing stores that leave plenty of space between the clothing on the racks.

By limiting the proportion of the image that causes our mind to “think”, we’re emphasizing the importance of the objects that do exist in the frame, thus increasing their perceived value in our brain.

It’s Not All About Neutrals

White Space in Photography - How to Use Negative Space in People Photography

Negative space images don’t have to be all about neutral backgrounds and bokeh that obscures the background beyond recognition. Whether you’re at a favorite lake or their family’s historic farmhouse, negative space images can be a great way to subtly reference location without making it the star of the show!

Look for backdrops that are relatively uniform in color and/or pattern, which will invoke the same visual feeling of breathing room and rest around your subject, while simultaneously visually cueing your location.

Why Does Negative Space Matter?

Now that you know how to create images of people that utilize negative space, it’s also helpful to understand why negative space images are important and why you should consider incorporating at least a few into every photo session.

Emphasizing Scale

Newborn Photography Scale - How to Use Negative Space in People Photography

Using negative space when you’re photographing people can help to emphasize the size of the person you’re photographing. For example, if you’re photographing a newborn and fill the frame in every image you take, you may have missed the ability to convey just how small newborn babies are relative to their surroundings.

By including varying degrees of negative space in your images, you will be better equipped to emphasize the scale of a newborn. Similarly, you could also consider using negative space images to convey how small a bride and groom are compared to the vast beach they were married on.

Give Your Clients Options

Headspace in Portraits - How to Use Negative Space in People Photography

If any part of your business plan includes offering digital images to your clients, keep in mind that many of your clients will want to post the images you’ve taken on social media. Many of the popular social media platforms are not very conducive to typical “fill the frame” portraits, forcing your client to either cut off the top of their head or cut off their shoulders (leaving them looking rather like a floating head as above).

Similarly, if a client requests a certain image printed on a canvas, images with negative space allow you to accommodate that request without worrying about part of the image getting cut off by the gallery wrap. By including negative space in a few images, you’ll be giving your clients more options and less frustration!

Give Yourself Options

Not only do images with negative space give your clients flexibility, they give you additional flexibility as the photographer as well!

Want to submit your image for the cover of a local magazine? Many editors want images with plenty of negative space to accommodate headline text. Want to start offering a Christmas Card design to your clients? Negative space images help make that easier. Want to advertise mini sessions on Facebook? Try placing the text in the negative space of one of your favorite images.

The negative space in this image allows room to add a text overlay.

Making an effort to utilize negative space every time you photograph people will give you more ways to use your images.

Wrapping it Up

How to Use Negative Space in People Photography

In a nutshell, using negative space when you’re photographing people can help bring attention to your subject. It can also showcase locations in an unobtrusive way. Negative space also helps emphasize movement and scale, add variety to your images, and offers more flexibility to both you and your client. It’s a great technique you can implement right away and it costs nothing!

Pop-Up Parking Garage & Rooftop Green Space Rises Higher When it Rains

05 Oct

[ By SA Rogers in Architecture & Public & Institutional. ]

Stormwater flooding, too few places to park and a lack of green space are three of the main issues plaguing every major city, and this strange but kind of brilliant building concept attempts to solve all three at once. ‘POP-UP’ by Danish architecture firm THIRD NATURE places a five-level parking garage topped with a public park on top of a stormwater reservoir, with the building’s height changing depending on how much it has rained lately.

On a dry day, all that’s visible of the POP-UP structure is the rooftop park, which essentially sits at ground level. But when rain falls, it fills the underground reservoir, causing the parking structure to rise higher in the landscape, highlighting its adaptability in the face of changing weather. The architects present it as an alternative to constructing a rainwater reservoir that’s empty most of the time or a mono-functional parking facility that takes up valuable urban space.

“By 2050, the Earth’s population is expected to grow to over 9 billion people,” says THIRD NATURE. “The migration to cities is on the rise and urban spaces are under pressure from the growing numbers of cars and traffic in the streets. With the quest for green, livable and human-scale cities cars and car parking have become an increasing challenge fighting for m2 in the dense cities – often at the price of urban areas and parks.”

“At the same time, climate changes require cities to handle huge amounts of stormwater generated by more and more powerful cloudbusts – this by building large water reservoirs under roads and squares. The situation calls for a rethinking of the way we establish parking, storage of stormwater and new urban spaces.”

They compare the building to a piece of cork in a glass of water. Hydraulic and mechanical lifts would help balance the weight ratios of parked cars in the structure to make sure it’s able to move up and down smoothly without changing the water level underneath. The two lowest levels of the parking structure would be off-limits, remaining underground to ensure the stability and buoyancy of the building.

Though an approach that reduces the number of individual vehicles allowed into a city would arguably be more practical, it’s also true that many places (especially in the United States) are likely to remain car-centric for the foreseeable future. Is this a realistic compromise?

8-Bitten: Space Invaders Street Art Tells Tile Tales

21 Aug

[ By Steve in Art & Street Art & Graffiti. ]

Urban street artist Invader has installed tile mosaics modeled after Space Invaders 8-bit video game characters in over 30 countries over the past 20 years.

Although he prefers to remain incognito like Banksy and many other street artists, Invader has a known personal history aside from his art. Born in France in 1969, he graduated from the prestigious École des Beaux-Arts in Paris though one wonders what his instructors think of his trademark works.

Classical training aside, Invader’s main artistic focus relates to the 8-bit graphic style of visual displays common to the first wave of electronic video games from the late 1970s. His choice of “Invader” as an artistic nom de plume reflects the influence of Space Invaders, one of the first shooter-style video games, released in 1978. The images above, captured by Flickr member Philosofia in Rome in June of 2011, are typical of the artist’s style and preferred placement in public urban settings easily visible but less than accessible.

We’ll Always Have Paris

Invader is not your typical tag & go, fly-by-night graffiti artist though many of his works ARE installed in the dead of night so as to avoid traffic and police. Instead, Invader typically plots his so-called “Invasions” of a chosen city far in advance, scouting out locations for his mosaics and semi-completing the works before he goes out to install them.

The artist’s earliest mosaics began appearing in Paris about 25 years ago. The examples above come courtesy of Flickr members Wally Gobetz (wallyg), Nelson Minar, and Ferdinand Feys.

High Plain Invaders

As time went by and word of Invader’s distinctive works spread, a black market for his pieces sprang up. Naturally, the artist disapproved of this – his works were and are designed to be not-for-profit installations.

In response to a rash of thefts and subsequent resales, Invader has made efforts to make his work more complex (and therefore more difficult to remove) and he’s also been placing them in higher, less accessible locations. The above images were snapped by Flickr members Allison Meier (allisonmeier), KnitSpirit, and victorillen in 2009, 2011 and 2009, respectively.

Miles Of Tiles

In June of 2011, Invader celebrated the installation of his 1,000th work in Paris alone. Over his “career” to that point, he had created 2,692 space invader style mosaics in 77 cities using approximately 1.5 million ceramic tiles. The mosaic above dates from February of 2013 and was snapped by Flickr member sinkdd in Tokyo, Japan’s famously trendy Harajuku shopping district.

Composition tips: simplification and negative space

06 Aug
Photo by Matthew Henry on Unsplash

Composition is about a whole lot more than the ‘rule of thirds’ or the ‘golden spiral.’ If you really want to understand what makes a photograph stand out, you need to dive deeper into the art of photography and photo composition… which is exactly what Ted Forbes did in this old episode of his aptly-titled YouTube channel The Art of Photography.

The episode was dug out of the archives by Fstoppers, and it was part of a larger series on composition, which is elaborated on in a blog Forbes was maintaining at the time called Composition Study.

But this episode in particular stands out, because it’s one of the deeper video dives out there on the subject of simplicity, minimalism, and negative space. Forbes starts with figure/ground relationships, and expands from that to explain how you create dynamism in a photograph, let your subject/figure breathe while drawing your viewers eye to that subject, and much much more.

Check out the full episode below, and then share your favorite minimalist composition in the comments down below:

Sony a7S II sends 4K video from the International Space Station to Earth

28 Jul

Last December a Japanese rocket brought cargo 249 miles above the Earth to the International Space Station. On that rocket was none other than a Sony Alpha a7S II, which was soon mounted on the outside of Japan’s KIBO module to take photos and videos of the mothership, so to speak.

Mounting a camera to a space station isn’t like putting a GoPro on your handlebars – the a7S II is enclosed in a specially designed aluminum housing with a radiator to keep it at a comfortable temperature in the vacuum of space. It’s mounted on a two-axis gimbal so, unlike prior cameras on the ISS, it’s not constantly looking straight down. The camera itself is basically the same as what you could buy off the shelf, and has an FE 28-135 F4 G OSS power zoom lens attached.

Head on over to Sony’s website to learn more about why the company’s high-sensitivity full-frame camera was chosen and how it all works. You can also find additional 4K videos to enjoy.
