I want to use nondestructive editing in photoshop using adjustment layers. However, I need a good program for cataloging those photos. I originally used a Lightroom workflow, but Lightroom just does not run well on my G4 ibook, so I figured a photoshop non destructive editing one would better. Originally I wanted to use iView Media Pro for cataloging, but they've recently been taken over by Microsoft (yikes). I tried Photomechanic, and I liked it, but I ran into a few hiccups with my workflow while using it (or any image-viewing program). I don't shoot RAW, so my master file is a JPEG. The problem here is I have to flatten the file to save it so I have to create an extra PSD apart from the master with my changes, which totally defeats the purpose. How can I overcome this? Should I convert everything to PSD when I import it from my camera? Otherwise, I have no idea. Also, what colorspace should I be shooting in? Is Adobe RGB more of a hassle that I won't really see in teh finished product? What resources can I look at on how to set Photoshop settings such as color profiles etc.? Thanks in advance.
