I recently got a book on infrared photography and it had some tips on editing the photos. The method I tried out was converting my photo to Lab Colour and then removing all channels except the "Lightness" channel. I did some playing around and decided I liked my photo with both "Lightness" and "b' on. But I can not figure out how to save my image with just those two channels on. Here's a low res version of the PSD that you can play with is you want. http://dl.getdropbox.com/u/28756/IR Tree_small.psd I really like the look that having both channels gives, but as I said I couldn't make it work. I must have fiddled with it for an hour at least. So any help would be great!
