Professional Photographers Using Linux?

thesun asks: "I'm a freelance writer and photographer and I'm wondering what Pro Photographers have done in regards to color matching and scanning under Linux, especially when going from slides to digital. I just can't get anything close to a good image when I scan a slide. They're blurry and the colors are so off that doing anything with my thousands of slides is proving to be prohibitively time-consuming. Are other Pros (or talented amateurs) having similar problems? Are there solutions out there I haven't found? (Sorry, I can't dump thousands into a piece of hardware---I'm looking for a way to make the most of my Epson Perfection 2400 with transparency adapter)."
