>What color space does Photoshop (6) open a file tagged ProPhoto RGB into?
Depends on the Photoshop 6 Color Settings [Edit > Color Settings]. It should
act as set for a profile mismatch. If you have 'ask when opening' checked for
profile mismatches it should present a dialog box on opening the file. Page
128-129 in the PS6 User Guide lists what PS will do for various color
management settings.
Ian Lyons has written a good essay on PS6 color.
