Hi folks -
I've just started experiencing a problem in Photoshop. At first, I thought it was due to the new OpenGL features in CS4, but it's a problem there even with that acceleration turned off. It also happens in CS3.
Here's a screenshot of what I'm talking about:
As you can see, the sky is severely posterized. This is after a couple of enthusiastic Curves applications, darkening it down quite a bit. However, the problem is only visible at magnifications of up to 66% (on this particular file). Once I zoom in further, it vanishes, and it doesn't show up in a print. Its appearance does seem tied to the size of the file. I only started seeing it when processing images out of my 5D Mk II.
Anyone got any idea what's causing this and how I can correct for it? It's driving me batty.
Cheers,
Peter
