Thanks, Don. As it happens, I use no coloring at all; I scan in 16-bit Grayscale in Epson Scan on a V700. Once I apply curves, screen sharpening, and do whatever spotting I think is necessary, I convert from the default Epson "grayscale" color profile to SRGB, take it back to 8-bit mode, and then save a JPG for posting. This is all in Photoshop CS6; I have not succumbed to Adobe's rental scheme yet.
I have in the past scanned in color but got some odd casts, and have even done split toning of various kinds. Eventually I elected to keep it simple. I can always re-do a scan if I want to try something fancy.
As it happens, I'm working on a new batch of plates right now. An example:FF-109, Happy families are all alike...
