Ok, so I'm a professional photographer, but never got into infrared photography before.
I just ordered a Light Craft Workshop R72 filter for my 17-40 f/4 USM attached to my Canon 7D and of course I've gone through various test shots doing custom white balance set to a tree or grass or anything green to just get the white tree effect. Well that doesn't work. Maybe the 7D has a high IR filter and that's why I can't seem to get the right exposure and basically I just blew 80 bucks for nothing (or at least until I get the Canon 1 D C ;) and I can have this converted to IR only).
I am doing the channel mixer thing that you see in every forum and I've played with the Hue/Saturation and Lightness and I can kinda get it, but nothing even remotely close to what I've seen off camera. (Basically everything red and the trees are obviously white).
After downloading the DNG Profiler from Adobe Labs I've also done the custom camera profile for EACH shot so that it's close to perfect for that color temperature and I still get pictures AFTER switching the camera profile having a lighter tint, orange sky and buildings, but the trees still are a strange color.
I've been thinking about buying a color checker passport just to save me a whole bunch of hassle since I assume that this will fix everything, but I'm not sure if that will solve everything. Of course it'll be convenient for everything else, but my main concern right now is IR photography because I love a new challenge.
