Something may not be kosher here. I see NO banding on the MacBook Retina display with the new setting invoked. I do see banding when off. Is the MacBook Retina a high bit panel (news to me)? If not, should we be suspicious that Adobe is doing some kind of dithering here to smooth everything out?
Hi Andrew,
Don't know what to think of that. I was pleased that you were apparently able to get a 30-bit performance, but was puzzled by the fact that you say that your nVidia graphics card is not a Quadro family card type (which according to nVidia is the only one that provides 30-bit output).
If nVidia say that it is not possible, yet you see what seems to look like 30-bit smooth gradients, then something in El Capitan, or in PS must do something to make it look like it is 30-bit.
Since the Petapixel article says that they got confirmation from Adobe that they changed something, I also get a suspicion that something else is happening, like dithering. Puzzling, to say the least.
Cheers,
Bart
