Here’s what I’m trying to do: with two or more IR filters having different cutoffs (separate exposures for each), I’d like to subtract one image from the other to achieve a "passband" effect. Each of these filters pass IR below their cutoff points–for example 720nm and 1000nm. I’d like to be able to create a false color image of (for example) red, IR from 720 to 1000nm, and 1000nm and below, assigning each of these spectral regions to R, G and B. What is the best approach to this using Photoshop CS?
