I was trying to test this -- when I found that the Photoshop CS color picker only has 8-bit *input*. I can only enter values from 0-255 into the R, G, and B boxes, even for an image in 16-bit mode. So I couldn't test whether it saved in a TIFF successfully or not, because I couldn't enter arbitrary colors in the first place. -- David Dyer-Bennet, <mailto:dd-b@xxxxxxxx>, <http://www.dd-b.net/dd-b/> RKBA: <http://noguns-nomoney.com/> <http://www.dd-b.net/carry/> Pics: <http://dd-b.lighthunters.net/> <http://www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>
