Oh crap, I forgot about the moire. Ok, there's another step we have to do.
Underneath the D&B layer, add another Channel Mixer layer:
R 0, +100, 0, 0
G 0, +105, 0, 0
B 0, +100, 0, +10
Make the mask black, then gently paint onto the moire areas.
Thanks. Yes, White LED should be the correct settings, so it can't be that.
With your recalibrations, have you now got the brightness exactly right? What luminance target have you calibrated to?
Check your sorting. It sounds like you're not on Filename.
No, sorry. This is a funny thing that Elements does, but PS can't. Elements automatically opens all images at full screen; where as Photoshop automatically at the next nearest standard zoom (66.67%, 50%, 33.33%, 25%, 16.7%, etc) below full screen.
It has nothing to do with Bridge or ACR, by the way. It's the same if you're coming from LR.
Terrific.
Yep, that's perfect. Which one did you end up choosing?
Yes, that's new. Just concentrate on the top number - the highest one.
Which lab are your prints from?
The "Dynamic" thing is the only reason I can think of that might be attributable to the screens themselves. If they're both on "Standard" then I'd say it's a Mac issue.
Did anything change two months ago that you can recall? New Mac, new calibrator, new OS?
Great. Can you check to make sure the screens aren't on their "Dynamic" colour setting. They most likely should be on "Standard".
It's not quite clear from your original question - does this problem happen all the time? Or only occasionally? And has it happened since forever, or can you remember there was a time when it didn't happen?
