HOW TO MAKE INFRARED PHOTO
Infrared photography was originally created for state surveillance, but, as you know, the use of any shooting techniques in creativity is only a matter of time (for example, as is the case with high-speed photography). Although a lot of time has passed since then, and even the infrared film has already been discontinued, you can easily recreate the look of infrared photos when post-processing in the editor.
Infrared photography turns traditional landscapes into mystical otherworldly images filled with bright shades of supposedly chewing gum and a clear accent in the sky. In fact, infrared photography converts green tones into peculiar shades of red, pink, pale pink or white – depending on the type of film used or the particular image processing method.
Why does all green change color?
It is assumed that this type of photograph captures a spectrum of light that is not visible to the human eye, hence all unusual tones. Infrared radiation has a longer wavelength than visible light, and the use of infrared photography allows people to shoot through haze and fog better than other types of photography (which is why it was originally used for observation).
If you are interested in experimenting with infrared film, the black and white version will be a more budget option than the color one. The use of black and white infrared film allows you to create clear photos even on the most foggy days. Although this is not the easiest type of photo playback, you can cheat – create “strange landscapes” on your computer.
Unfortunately, not everything can be easily reproduced in Photoshop, and you still need a special filter to start the process. Fortunately, it is relatively inexpensive and easy to find in any specialized photo equipment store.
Landscapes are the most common objects for infrared shooting, as they usually contain a lot of green tones. The bright blue sky becomes dark blue or black, while the green tones acquire a pale pink tint. Since infrared photography requires the use of slow shutter speeds, shooting live objects, people, or animals can be quite difficult.
How to take an infrared photo
The trick of infrared photographs is that after you attach the filter, you will not be able to see anything in the viewfinder. This is because infrared filters are designed to block all visible light. Because of this, you will need to compose the shot and focus before attaching the filter.
Procedure for infrared shooting
Set the tripod on a stable surface in front of the subject, then attach the camera to the tripod. Build a composition. Set the focus ring to the auto – you will focus after you attach the filter.
The aperture must be of the order of f / 16 to ensure that the entire scene is in focus. The ISO value should be 100 or 200 to reduce the amount of noise in the photo. The shutter speed will vary from 1 to 30 seconds, depending on the subject, so you will need to take some test photos with a filter to determine the appropriate shutter speed.
Shoot in RAW format! This will make the post-processing process much easier.
After you have set all your initial settings, set a filter, automatically focus the image and take a photo. And after you determine the correct shutter speed, you can take all the other pictures.
This is the fun part of the whole process. Depending on the type of filter used, the resulting image will be almost completely purple / violet / red. Dont be upset! It should be. These tones are known as “false colors,” which can be quickly changed in the editor.
Open the image in Adobe Photoshop. Create a new adjustment layer, then select Channel Mixer. Essentially, you need to swap the red and blue channels. To do this, select the red channel and drag red to 0% and blue to 100%. Now select the blue channel and, conversely, drag the blue one at 0% and the red one at 100%.
You can leave the photo as is or continue to make changes to the contrast, saturation or vibrancy of the image. An inconspicuous hue can turn into bright and rich with just a few clicks of the mouse.
By entering each individual channel (red, green, blue), you can also increase the amount of each color in the final image.
Do you want to get a lot of blue in the image, but do not want the pink tones to be too saturated? Go to Image -> Hue -> Saturation, select Red and drag down the saturation bar until the reds turn pale pink.
