From time to time I have extolled the virtues of RawDeveloper.
I remember Mark commenting on the Win/Mac problem before (Hi Mark!).
I use PS or LR when there is a heap of images to process at once, and the results are for mags etc or for domestic use.
For fine art though, it'd RD most of the time.
Th images are sharper and cleaner. The deconvolution sharpening to correct antialiasing as part 1 of 3 pass sharpening , works much better for me than the options in PS/LR.
If I want further sharpening options I use Astra Image, but alas to use that I must swap to Win via Parallels. Mark would find it much easier. Astra Image has it's own problems, being so algorithm intensive that you are limited to relatively small image sizes.
No program does it all, so it's compromise or devising the best strategy for individual situations.
Fun and games as usual
