Photoshop and Color Mode I shoot a lot in RAW format and can convert to 8 or 16 bit color mode TIFF formats. Photoshop 7 can handle both but there are more options for 8 bit. I cannot see any difference visually in the screen or printed images (Epson 1280). Is there any advantage to the 16 bit I don't know about?

Scantips.com discusses this. I nearly always scan at the highest bit depth, even though it takes longer. The value of this is that you have a much wider gamut of colors to work with when you do tonal (Levels or Curves) correction, or color cast correction. When you do your tonal correction and look at the histogram afterward, you will rarely, if ever, see the snaggle-tooth effect you get when you correct in 8-bit mode. Gaps in the histogram indicate image degredation. You're right, you have to go to Image Mode and drop the bit depth to 8 before Photoshop lets you do much further editing. You might consider saving raw scans at 16 to CD's to archive. If I were a pro shooting for my livelihood, I'd do this.

I used the word "scans", since that's what I do. The same applies for your digital camera captures. That's a high-level camera you're using, if you're capturing 16-bit. I think you're right to convert to TIF.
