Here is the list of photo related software I have for Windows:
Photoshop CS2 (Windows & Mac)
Photoshop Elements 6 (Windows & Mac)
Paint Shop Pro X (Windows only)
Picture Window Pro 3.5 (Windows only)
Portrait Professional 8 (Windows only)
Neat Image (Windows & Mac)
PTLens (Windows & Mac)
Vuescan (Windows, Mac, Linux)
Faststone (Windows only) freeware
Panorama Factory (Windows & Mac) old freeware version
Virtual Photographer plugin (Windows only) freeware
I rarely use Picture Window Pro, Portrait Professional, and Panorama Factory though. The only reason I have PSE 6 is because it supports later versions of ACR that can handle my A700. Unfortunately, PSE has pretty serious gui bugs which makes it a pain in the butt to use sometimes. Also, it only has basic shadows/highlights rather than both basic and advanced like in PS. It also has a simplified curves control, but that hasn't been a major issue. Also, no masks, but, again, that hasn't been a big issue most of the time. The straighten tool in PSE is better and easier to use than the arbitrary rotate in PS. The one in PSP is much better than both though. In many ways PSP has the better interface and I like it the best *except* for no ACR, only basic shadows/highlights, no smart sharpen, and many of the functions do not have the instant preview like in PS. If I could pick and choose I would take 65% of PSP + 35% of PS. I never use Bridge or the browser in PSE and PSP. I have found that Faststone is much better and faster than any of them. It works with *all* the raw files I have. I didn't see PSE 6 on the Adobe website since the current version is now 7 so I don't know how someone would get the Mac version in order to switch the license.
It looks like most of the software I use would need to be replaced with other programs for use on a Mac. Some aren't that important though since I don't really use them much.
I was shocked to discover this afternoon that I don't have any of my app CDs here in Hawaii.
I keep them all together and somehow I ended up here without them. I always have them, but on the long road trip we went on in the spring I had more space in the SUV so I moved the CDs out of the normal place and somehow I forgot to put them back in the luggage I used to bring to Hawaii. Ouch. I sure hope I have no problems. Some of my programs are downloaded (PWP, PSP X, NI, etc.) so I have them on my external hd, but the main program I don't have is PS. The CD is somewhere back in Austin.
