digital infrared

So first step is to open the photo that you want to use then you open the channel mixer in the adjustment layer and choose the black and white infrared RGB. Once you are in the mixer you can make further modification to the photo if you are trying to bring out the greens you can pull up the greens in the photo by using the sliders. If this is not bring out the results you are looking for you can convert the image into black and white with the black and white layer mask then from the pull down menu choose infrared. If you want to control the opacity of the infrared you can by sliding the opacity down on this layer. this will bring up the color in the photo if you dont want the color to be there then open the hue/saturation layer and bring down the saturation all the way then you can bring down the opacity on this layer and not have the color show through.
