Thanks for the software suggestions. I'm on a Mac so some of them I can't use, although I remember Infranview from way way back. Gimp looks like it has been improved a bit, although still X11 based. I'll try downloading the demo of Photoshop Elements when I have time to play with it.
Maybe I should mention what I have now. I moved up from iPhoto to Aperture earlier this year. I'm still learning it's features but I'm pretty happy with it. I really like how good the highlight recovery is. I wish it had non-destructible local modifications like LR2.
Mitch's B&W work was what inspired me to get the GRD2 and I also picked up Lightzone. I've ignored Lightzone for quite a while and just started playing with it again last night. I see a lot of the advantages more clearly then I did before. I haven't been happy with what I've tried doing in B&W so I'll starting playing with Lightzone again.
I do have a few questions. Can I do things like removing the rope and bottle with this software? I haven't looked into how to do this. I assume Gimp can if/when I learn it. What useful tools would Photoshop Elements add on top of these two? I remember someone here was testing some new software that sounded like it would be a better Lightzone. Does anyone know what came of that?
Thanks again for all the great suggestions!
