Hello and welcome to the tutorial.
If you have been put off infrared photography because of all the hastle with film storage etc, you can now make convincing infrared shots with your digital camera and a few tweaks in Photoshop :)
Stock:
1. Open up the stock image in Photoshop and duplicate the layer. On the top layer, you need to give a slight gaussian blur. Around 10 pixels should do it, or to your own taste.
2. Above these layers, insert a Chanel Mixer adjustment layer, and use settings similar to mine:
3. When you are happy with how the channel mixer has turned out, make another new layer above it. Edit > Fill and use 50% gray.
4. Filter > Noise > Add Noise. Make sure it is set to Monochromatic and Gaussian, setting the amount to taste. I have used 20 in this tutorial.
5. Now, the final step is to make a Levels adjustment layer underneath your Channel Mixer. Here are the settings I used, but they will depend on what you used in the other steps. Just personal preference :) Set this noise layer's blend mode to overlay.
Thats it, you should wind up like something below. Hope the tutorial is useful to some of the photographers out there :)
