3. Processing Infrared Photos in Photoshop
The Photoshop part is simple enough. The main step involves swapping the red and blue channels. This will produce an image where the cooler parts (sky, water etc.) will appear blue and the hotter parts (trees, buildings etc.) will appear white, with a hint of red.
In some cases, the image actually looks better without the channel swap. I processed this image of a field and trees without the channel swap step because it gave a more interesting, artistic feel:
For most images though, the channel swap is preferred. I use Photoshop’s adjustment layers for non-destructive editing:

Here is the processed version of the image we looked at earlier:
I hope that you found this introduction to the world of infrared photography useful. Shooting and processing infrared photos may look intimidating at first, but it is quite straightforward once you get the hang of it.
