Well, this might just be the temporary solution to my problem!
I have the Creative Suite CS5 for Mac. Unfortunately, my Mac died just before Christmas. I'm hoping it can be fixed but in the meantime, I can only process photos at work (where I have CS5 on both my Mac and my PC--but also have actual WORK to do, which prevents me from having time to process photos).
I tried downloading Gimp and using the Nikon software to process raw files then gimp for additional processing, but it just isn't really working well for me. I can't get a good handle on making the workflow not seem tedious, plus I just don't really WANT to learn new software right now. I want PS!
I have a PC laptop at home, but no Windows-based Adobe software. Yeah, a laptop is not ideal for photo processing, but it's better than nothing! I think I'll give the CS2 a try when I get home--all I need is something to use until I either get the Mac fixed or replaced.
