(Photoshop) Infrared (IR) image with Photoshop CS

If you don’t have an IR filter to take IR images, you can use Photoshop CS to create IR images. Let follow these steps:
1. Add channel mixer from layer pallet

2. Mark in Monochrome box and adjust parameters as follows:
Red :+70, Green: +100 and Blue: -84. You can adjust these parameters base on your images. Basically we need to add brightness to foliage and reduce brightness in blue area (sky).

3. Create a duplicated layer by dragging “Background” layer over a new layer icon. Then change a “Background copy” layer to “Screen” mode with 64% opacity in order to brighten green area. This is an optional step. If you feel that the foliage looks bright enough, you can skip this step.
4. Create a new layer and fill the layer with white.
5. Add noise (Filter>Noise>Add Noise). Please ensure to check Monochromatic box. I use 14.58% for Amount of noise. Anyway this is not solid value so you can adjust this value to create grain in your image.
6. Change Layer1 to “Multiply” mode so you will get the IR image yeahh.

7. These following steps are optional. Create a new channel mixer above “Channel Mixer 1” and adjust parameters as follows: Red +90, Green +34 and Blue -2. You will get pink tone IR. Try to play with some parameters in channel mixer so that you will see how beautiful your image is.
8. Let add more effect. Copy your “Background” layer and move it between “Channel Mixer1” and “Channel Mixer2”
9. Then adjust “Background copy2” mode to “Soft Light” mode with 32% opacity.
Wow this is your IR image. This is just a guide line so let adjust parameters to see how your images will be changed.
