Mark and others, I'd like to focus on the OOG overlay behavior and what to do with it.
I just found something odd on this end. I opened an image in ProPhoto RGB that has a lot of saturated colors (part of my Gamut Test File, can post if people need it).
1. Setup a soft proof using my Epson 3880 profile, RelCol.
2. Ask to see OOG overlay. Note that if I go back into Proof Setup and toggle to another profile, the OOG overlay updates as expected. Return back to Epson profile.
3. Open Proof Setup and toggle between RelCol and Perceptual, I see NO difference in OOG overlay which is odd.
4. Duplicate this image. It still has the proof setup with Epson profile, I turn OFF OOG.
5. On duplicate, I use Color Range to select OOG. I then invoke the Quick Mask so I can see what's been selected.
Expected results: Quick Mask overlay and OOG overall in original match.
Actual results: They don't match at all! Not even close.
Color Range is selecting far more colors than what I see with OOG overlay, what's up with that?
