Hi Dan, I was hoping you'd get a moment to chime in. I've been talking with Jay from Hi-Fi Ink about this too; using his color settings, then changing back to North America General Purpose 2, as Jay suggested. That works to get a better view of the image. To test this theory further, since I've been using UltraSeps 2 for the last couple of years, I switched over to those color settings, and they also gave a very dark view, so I went back to NAGP 2 and will sep the old fashioned way. All this being said, I don't believe it's the Color Setting change necessarily, because this is a new problem. I posted some tropical birds we did at the end of June, stepped with Hi-Fi Ink, and had no problem at that time with images being dark. This really just started last week. Also, when I open the same image on another computer running PS CS3, with the default color settings, it looks fine. I'm mostly thinking I fat fingered something on the keyboard that I just can figure out. I may just finally subscribe to Photoshop CC 2017 and see if that's it. It is time to do that I think... thanks all.
