How to Mimic a Digital Cyanotype Using Photoshop with Ease

15 Dec

The post How to Mimic a Digital Cyanotype Using Photoshop with Ease appeared first on Digital Photography School. It was authored by Ana Mireles.

A Cyanotype was a popular film printing process that gave an appealing, beautiful cyan-colored tone to an image. Sounds nice right? Would you like to create one? Don’t worry – you don’t have to go back to the darkroom or become a chemist and waste tons of material to do it. I’ll show you how to create a digital Cyanotype using Photoshop.

EXTRA TIP: Because you achieved a Cyanotype by applying light-sensitive emulsion onto the paper (or surface) you were going to print on, the first thing you need is a background that mimics this effect. If you’re feeling crafty, you can buy yourself a brush, some paint and physically do your background. Then scan it and make it the size and resolution that better fits the image you’re going to use.

However, if doing so is a hassle, you can create your background digitally. Because I promised you digital Cyanotype, I’ll show you the latter.

Step 1:

First, pick the Brush tool from the Toolbox. Here, you’ll be able to pick the size and type of brush. From the Options Bar that is now active, choose your color. Select a brush with a wide tip, like a fan, so that the effect emulates brushstrokes and not a pen or a marker. The brush size depends on the size of your document.

It’s okay to make it uneven. Remember, the original method used hand-made techniques, so uneven gives it a nice unique look. For now, use black because the tone is applied later. Since we’re discussing color, I’ll use this space to tell you that, in my experience, any photo with a black or dark background blends easily. However, it’s possible to use any image.

Step 2:

Open the image you are turning into a Cyanotype and desaturate it. To achieve this, you need to go to Menu -> Adjustments -> Image -> Hue/Saturation. Move the Saturation slider all the way down to the left.

Once you have your image, drag it into the canvas where you created the brushstroke background. It gets pasted as a new layer in that document. Drag the corners to make it the right size for your background and click on the check mark to apply.

Step 3:

Select the layer with the brushstrokes and add an Adjustment layer of Levels. Move the black and the middle tones to lighten the color so that your black becomes dark grey.

Step 4:

Next, select the top layer – the one with your image, and add another Adjustment layer. This time choose Color Balance. Here you can make a combination to find the right tone of blue you want. As a starting point, use the ones I’m using: Cyan -62 and Blue +95.

Step 5:

Once you’re satisfied with the color of your image, you can choose to make it less intense by adding another Adjustment layer. Always keep the layer on top selected so that the new Adjustment layer covers all layers. Add a Hue/Saturation Adjustment layer and move the Saturation slider a little bit to the left. Be careful not to go too much into the gray because it may no longer resemble a Cyanotype.

Step 6:

If you can see the borders of the image you pasted, the balance isn’t right. It’s not incorporating well with the background. To fix this issue,  change the layer Blending Mode. Select the image layer and open the Blending Mode menu. Choose Lighten or Screen to achieve a better result.

However, if there is still some evidence of the border, choose the Eraser tool from the Tool Box and lower the opacity. Choose a brush with soft borders and erase so that you can defuse the border and make it a smoother transition.

Your finished Cyanotype

You should now have your finished Cyanotype. I hope you enjoyed the tutorial and gave it a go. Please share your results in the comment section below.

How To Mimic a Cross-Processing Effect in Photoshop

11 Nov

How To Mimic a Cross-Processing Effect in Photoshop

Cross-processing is a technique that comes from the darkroom days. You would purposely develop film in the wrong chemicals to achieve special color effects. When no film or chemicals are involved in digital processing, it is possible to mimic a cross-processing effect in Photoshop. I’ll show you how in a few easy steps.

The technique is called cross-processing because it referred to the processing of negative film with a chemical developer designed for reversal film. Or vice versa. You will also find it under the name ‘x-pro’ or ‘Xpro.’

Of course, replicating this effect directly in camera isn’t possible, but you can reproduce the results with Photoshop. You can make your image look like it’s the result of cross-processing.

In Photoshop there’s often a preset that solves your problems. Cross-processing is no exception. I will show you a step-by-step way to do it so that you can have more control over the end result. There is no right or wrong. One is no better than the other. It’s about giving you a choice so you can decide what works best for you.

So, let’s get started.

The Cross-Processing  Preset

To find the ‘Cross-processing’ preset add an ‘Adjustment’ layer. Click the button at the bottom of the layers panel and choose ‘Curves’ from the pop-up menu.

Curves - How To Mimic a Cross-Processing Effect in Photoshop

From the ‘Properties’ panel open the ‘Preset’ menu. Change it from ‘Default’ to ‘Cross-Process (RGB).’

Cross Process RGB - How To Mimic a Cross-Processing Effect in Photoshop

Notice the colors of the image are very saturated and have a definite green color cast. The graph now has three colored lines: Red, Green and Blue. Each line has a different shape.

Graph - How To Mimic a Cross-Processing Effect in Photoshop

Those three colored lines represent the three channels (Red, Blue and Green) adjusted by the Preset to create the effect. Therefore, you may create this effect manually without using the preset. You can achieve this manually by tampering with each color channel separately.

Using Curve Properties to Achieve the Cross-Processing Effect

For this, instead of changing the preset menu, open the ‘RGB menu.’ Go into each color and move the curve in the graph.

Curves - How To Mimic a Cross-Processing Effect in Photoshop

However, many people don’t find the ‘Curves’ tool very comfortable. So I’ll show you a tool to work with sliders to achieve similar results.

Discard the ‘Curves’ layer or hide it by clicking the ‘Eye’ symbol to the left of the layer. That way you can work with the original image. Now add an ‘Adjustment’ Layer with a ‘Channel Mixer.’

Channel Mixer - How To Mimic a Cross-Processing Effect in Photoshop

In the Properties panel, find the ‘Output Channel.’ Here, open the drop-down menu to change from one color channel to another.

Output Channels - How To Mimic a Cross-Processing Effect in Photoshop

In each color output channel, you can see the corresponding color slider will be at 100%, while the other two are set to ‘0.’ So, in the ‘Red’ channel, the Red slider is set at ‘100’ while Green and Blue are at ‘0.’ In the ‘Green’ channel, the green is set at ‘100’ and the Red and Blue are at ‘0.’ In the ‘Blue’ channel, the blue is set at ‘100’ with Red and Green at ‘0.’

Move the sliders to create your own cross-processed image. Move all three channels sliders around until you’re satisfied.

Red color cast - How To Mimic a Cross-Processing Effect in Photoshop

Remember, you don’t need to duplicate the result that the Preset proposed. But if that is your objective, you don’t need to go into moving any setting individually.

To reiterate, to achieve an image that suggests cross-processing, more than one formula exists.

Green Color Cast - How To Mimic a Cross-Processing Effect in Photoshop

A few things to keep in mind:

  • Cross-processing was initially a ‘mistake’ (even if done on purpose) causing unpredictable results. Thus, feel free to experiment and be creative because there is no wrong answer.
  • Cross-processed images look oversaturated with a distinct color cast.
  • Using the wrong chemical would often distress the image, to mimic this you can introduce some noise.

Adding Noise to Your Image

To add noise to your image, select your image layer and go to Menu -> Filters -> Noise -> Add Noise. A pop-up window will open giving you a preview of the filter you are applying and the sliders to adjust it. Make adjustments to your preference.

How to Mimic Lomography in Photoshop with Ease

03 Nov

Ever wondered what Lomography is?

Have you seen Lomo images and wanted to know how to do it? Do you know what Lomo photography is but don’t want to go back to film or buy more cameras?

If you answered yes to any of these questions, read on to learn about Lomo, and how to achieve a hassle-free, totally digital image like it.

What is Lomo?

You’ve probably heard of this term or its more colloquial name Lomography. It became very trendy over the last decade, and there are even workshops, contests and more dedicated to it.

It refers to a style of photography made with a particular brand of camera from Austria called Lomo. Thus, the name of the technique comes from the camera brand. Different models create a different kind of image.

How to Mimic Lomography in Photoshop with Ease 1

What is Lomography?

Regardless of the model of camera, the make is mostly plastic including the lens.

Sometimes they have light leaks and allow very little control over the settings. Therefore, the results are fun and unpredictable. While technically they have photographic ‘flaws,’ it creates a particular style that created an entire visual culture around it – Lomography.

How to Mimic the Lomo Effect in Photoshop

As I’ve explained, Lomo photography can be unpredictable, and also includes different models of camera that create a different kind of photograph. Therefore there’s no specific set of rules.

I’ll mention some of the most common and characteristic effects of the Lomo cameras and how to achieve them using Photoshop. These are not set in stone. The fun part about real Lomo or digital Lomo effect is that you can be as creative as you want.

1. Vignette

Most of the images created with a Lomo camera, especially if made with long exposures, have a vignette.

To create a Lomo image in Photoshop, you need to duplicate the background layer by dragging the existing one to the bottom into the New Layer button, or by going to Menu-> Layer-> Duplicate Layer.

How to Mimic Lomography in Photoshop with Ease 2

Next, go to Filter-> Lens Correction (If you don’t immediately see it in your version of Photoshop, go inside ‘Distort’ to find it). In the ‘Custom’ tab, move the slider called ‘Vignette.’ Once satisfied, apply the filter.

How to Mimic Lomography in Photoshop with Ease 3

Duplicate this ‘Vignette’ layer. Go to Menu -> Blur -> Gaussian Blur. I’ll set it to 3 pixels, but this is entirely up to you.

Now use the ‘Eraser’ tool. Start to delete the center and slowly widen your moves towards the outside. We do this process because the edges are not super sharp in Lomo photography, due to the lenses often being made of plastic.

How to Mimic Lomography in Photoshop with Ease 4

2. Grain

Since Lomo cameras use film, you can give the illusion of analog photography by adding a little grain to the image. To do this, select the first Vignette layer and go to Menu -> Filter -> Filter Gallery- > Artistic -> Film Grain.

Again, the quantity is for you to decide as it’s an authors choice and not an exact recipe to follow. I’ll do 4 with an intensity of 3.

How to Mimic Lomography in Photoshop with Ease 5

3. Color Saturation

Finally, Lomo’s characteristic colors are overly saturated. To achieve this, while there are many ways in Photoshop, I like to do it channel by channel with the ‘Curves’ tool. Firstly, add an adjustment layer.

To do this, click on the button at the bottom of the Layer panel with the circle symbol, and choose ‘Curves’ from its pop-up menu. You can move around the settings in each channel separately by opening the ‘Preset’ drop-down menu as per the picture below:

How to Mimic Lomography in Photoshop with Ease 6

You may continue adding some adjustment layers to keep modifying the effect. I added a ‘Gradient Map’ with an ‘Overlay’ blending mode. I also added a ‘Vibrance’ and ‘Saturation’ layer where I pushed the vibrancy up a bit more. Experiment until you are satisfied with your adjustments.

Remember that you can double-click any adjustment layer to open its properties and move the settings as many times as you want.

How to Mimic Lomography in Photoshop with Ease 7

Once your adjusts are set, go to Layer -> Flatten Image which will compact all the layers you created into one. If however, you’d like to keep your layered file first, save a copy of it before you flatten. Once your image is flattened, go to Menu -> Filter -> Sharpen -> Unsharp Mask and apply it to your image.

Be careful not to exaggerate this because it will enhance the film grain from before. Just move the sliders while keeping an eye on the preview window.

That’s it! Take a look at the before and after images below.

How to Mimic Window Light in a Studio Environment

24 Jun

One of the most common reasons you hear from photographers who avoid off-camera flash lighting is that it looks artificial. Yes, studio lighting can look artificial, but sometimes that’s part of the charm. Nobody claims portraits made with a ringlight look natural, but that doesn’t stop the thousands of photographers (myself included) that use them all of the time. But that doesn’t mean that it is impossible to mimic window light in the studio.

In fact, that’s kind of the point most of the time.

How to Mimic Window Light in a Studio Environment - portrait of a lady in the studio

Obtaining natural looking result in a studio is fairly easy with a few basic tools and some know how.

With studio lighting, you can create whatever lighting you want at any time. Providing that you have the right tools (and they are pretty basic), creating natural looking portraits in a studio environment with off-camera flash is exactly as difficult as creating portraits using window light.

Why is window light so wonderful?

b/w window light portrait - How to Mimic Window Light in a Studio Environment

Window light has a lot of wonderful qualities that make it a great choice for photographing people and other subjects.

In a nutshell, windows give you a constant (during daylight hours) and large light source to work with. The light itself is soft, diffused (assuming that direct sunlight is not entering through the window), and lends itself well to virtually all subjects including portraits.

It also tends to be very directional (depends on how you position yourself and the subject in relation to the window), making it easy to work with to shape your subject.

two b/w portraits - How to Mimic Window Light in a Studio Environment

Window light can give a variety of results depending on the time of day and the size and shape of the window. As such, there is no one size fits all solution to mimic window light and recreate it in the studio.

On top of that, we see things lit in window light all day, every day. It is a very natural state of things and it’s how we recognize the world around us. This familiarity makes window light an obvious choice.

Add to that that the master painters created a great many of their portraits in a studio lit by window light. The most obvious point of reference here would be Rembrandt since this style of lighting is one of the most common techniques that photographers use today.

The reasons for unnatural looking light

b/w portrait with ring lighting used - How to Mimic Window Light in a Studio Environment

Some light sources, like the ringlight used here, are by nature very unnatural looking. When trying to recreate natural light, try to stay away from specialist tools like these and tri-flectors.

There are a couple of reasons why studio lighting can look canned and unnatural. These are:

  • Too many lights – When using natural light, you’re usually shooting with only one light source. Perhaps there’s a reflector involved or there might be multiple windows, but for the most part, it’s one light. Going into a studio environment where a single setup can involve a key light, a fill light, a hair light, two rim lights and two background lights can feel both complicated and wrong (unnatural). Fair enough.
  • The modifiers are too small – In most cases, windows are quite big. This means that the light source you are using to light your subject is large. Big light sources give soft, flattering light. Add some mesh curtains to that window and the light gets even softer and more diffused. What does that tell you about the size of modifier you need to use on your studio portraits to get soft light?
  • The lights are too far away – In terms of the softness of the light, it’s the size of the light source in relation to the subject that determines how soft or hard it appears. If you have an 8′ octabox twenty feet from your subject, it will appear quite small comparatively; therefore, the light will be a bit hard. If you have a small pop-up softbox on there, it will be even harder. Bring your lights in as close as you dare to get for the softest light possible. If you have a small modifier, I recommend having it so close you can barely shoot past it without getting the light source in the frame.
  • You’re using an odd light source – Specialist lights, like the ringlight used in the image above, create light that you wouldn’t normally find in natural scenarios. Even if a viewer doesn’t understand the why behind it, people are quite intuitive when things seem weird. If you’re going for a natural look, avoid lights like these.

How to recreate and mimic window light in the studio

Here, you’ll see just how easy it is to mimic natural light in a studio environment. Here’s what you’ll need to get started:

  • An off-camera light source. Strobes, flashguns and continuous lights will all work equally well.
  • A large light modifier. These examples use a 5′ Octabox (or recessed softbox as PixaPro like to call it), but anything will do. If you don’t have any large modifiers yet and are unsure about what to get, consider starting with a large translucent umbrella. They’re big, dirt cheap, fold away easily and produce a nice, soft light.
  • White or silver reflector. This one’s optional, but you should have one anyway. If you’re using a really big modifier, the wraparound of the light may mean you don’t even need it, but they are useful for filling in dark shadows on the unlit side of your subject.

Setting up

behind the scenes studio shots - How to Mimic Window Light in a Studio Environment

A medium sized octabox placed close to an above the subject and a silver reflector was all it took to create these images.

To get started, place your light about three or four feet from your subject. Turn the light so that it’s forty-five degrees (in relation to your subject.) Raise the light up as high as you can (making sure the subject still has catchlights in their eyes). High ceilings are a bonus.

The reason for this is that with window light, the light is often coming from above. The window is shaping the light into the room, but it is still coming down into the room. If you’re using modelling lights or continuous lights, watch the catchlights in your subject’s eyes. Once they are falling towards the top of their eyes, you’re good to go.

Likewise, also watch where the shadows are falling. If the contrast seems too high, introduce a reflector. This does take practice, so don’t worry if you can’t tell just yet. It may help if you squint your eyes tightly. This makes it easier to see the contrast. In these examples, the silver reflector was placed flat and in front of the subject at around waist level.

Now, all that you have to do is to take a light meter reading (or take a test shot), adjust your settings (either in-camera or on the flash) and start taking photos.

portrait of a lady in pink - How to Mimic Window Light in a Studio Environment

To start with, try having your subject turned toward either the light or the camera. Beyond that, there’s not really much else to it.

How to Mimic Window Light in a Studio Environment

Practice makes it simple

If you are completely new to off-camera lighting, this may seem like a lot to get. I promise it’s not. Once you’ve set this up a few times, it becomes so easy that there’s not much more effort involved than placing someone in front of a window.

The advantages here are that you aren’t at the mercy of the weather or the time of day and once you get started with a set-up, the light won’t change unless you tell it to.

Just remember to keep the light both high and close and there isn’t much room to go wrong.

Putting it to use

If you’ve had any hesitance to use studio lights for any of the reasons listed in this article, hopefully, you can see that with the right techniques, you needn’t worry at all. Honestly, it’s not as difficult or complicated as it seems. If you’re still unsure, rent a studio for an hour and put it to practice. You may be surprised at what you find out and learn.

Demo: Gudsen adds ‘Mimic Motion Control’ to Moza Air gimbal

22 Aug

Chinese gimbal manufacturer Gudsen has released new firmware update for its Moza Air that offers new ways to control the motion of the head, as well as better timelapse features for long exposures. The Moza Air—which is designed for cameras ranging from CSC bodies to high-end enthusiast DSLRs—now allows operators to control the direction and angle of the head remotely just by moving a small handlebar-mounted control unit.

With the supplied thumb controller attached to a set of handle bars, the Bluetooth-paired head mimics the motion of the bars so that the mounted camera can be moved by small increments without the user even touching the gimbal.

Pitch, Roll and Yaw movements can be controlled while a read-out on the thumb controller’s screen lets you know the exact position of the head.

The second part of the update adds improved timelapse functionality, ensuring the head is still during long exposures. It does this by using a ‘move-stop-shoot-move’ process rather than a continuous moving path across the programmed points. The timelapse interface on the Moza Assistant app has also been updated, allowing more control in a clearer design.

For more information, visit the Gudsen website.

This CMOS sensor with 3D-printed microlenses is designed to mimic predator vision

23 Feb

A research team at the University of Stuttgart, Germany has proposed utlizing a 3D printer with ultra-short pulse laser-technology to print multi-component microlenses directly onto the surface of a CMOS image sensor. Doing so would create a ‘foveated’ imaging system: one with greater resolving power in the center, similar to the vision of predators in the animal kingdom.

In the research project, lens groups consisting of one of four types of tiny doublet lenses were printed directly onto the chip, after some functional layers like the existing microlenses and the color filters had been scratched off. The individual lenses come with 35mm equivalent focal lengths of 31, 38, 60 and 123mm which together give the system a field of view of approximately 70 degrees but with extra resolution at the center.

The footprint of the optics on the sensor is less than 300 x 300µm and the height of the lenses is 200µm, allowing for the design of highly miniaturized cameras that could be used in areas such as endoscopy, optical scientific instruments, optical sensing, camera drones or security.

Improvements to the current version could include anti-reflective coatings on the lenses, the use of triplets or more lens elements for aberration correction and the inclusion of absorbing aperture stops.

The paper by Simon Thiele, Kathrin Arzenbacher, Timo Gissibl, Harald Giessen, and Alois M. Herkommeris is titled ‘3D-printed eagle eye: Compound microlens system for foveated imaging’ and can be read in its entirety on Science Advances. 

Abstract:

We present a highly miniaturized camera, mimicking the natural vision of predators, by 3D-printing different multilens objectives directly onto a complementary metal-oxide semiconductor (CMOS) image sensor. Our system combines four printed doublet lenses with different focal lengths (equivalent to f = 31 to 123 mm for a 35-mm film) in a 2 × 2 arrangement to achieve a full field of view of 70° with an increasing angular resolution of up to 2 cycles/deg field of view in the center of the image. The footprint of the optics on the chip is below 300  × 300 um, whereas their height is less than 200 um. Because the four lenses are printed in one single step without the necessity for any further assembling or alignment, this approach allows for fast design iterations and can lead to a plethora of different miniaturized multiaperture imaging systems with applications in fields such as endoscopy, optical metrology, optical sensing, surveillance drones, or security.

Play-Doh People: Manipulated Portraits Mimic Old School Horror Movies

06 May

[ By Steph in Art & Photography & Video. ]

play doh people main

Lumps of modeling clay in shades that match human flesh are globbed into the hollows of what should be faces in this series of portraits mixing photography with sculpture. Artist José Cardoso gets under the viewer’s skin with visuals that disturb and fascinate, perhaps prompting some to reach up and ensure that their own faces are still intact after checking out the entire collection.

Warped and distorted, with ragged edges, holes from poking fingers and glimpses of bone-like foreign objects embedded within, the Play-Doh takes the place of ordinary features, completely obscuring them or making it seem as if some careless child’s hand has ripped them away. There’s no hint of an attempt at modeling an actual representation of a face – just lumps. (The ones with bits of hair and dirt in the dough are especially cringe-worthy.)

The series is deliberately reminiscent of the special effects in old school horror movies, especially those of David Cronenberg, and it’s easy to see that influence here. As scary as they may have been at the time, when we look back at films like Naked Lunch, The Fly, Videodrome and Shivers we can see that they clearly made use of a whole lo to rubber and clay to achieve those gory effects. In comparison, Cardoso’s work is quite restrained, but its subtlety is startlingly effective.
