Hi guys, Am having a bit of a problem exporting RAW images from Lightroom 3 to Photoshop CS5 (command - E). I am sending them 16 bit Prophoto RGB with no compression into CS5 (and staying in ProPhoto).
The problem is I am getting faint magenta, blue and sometimes green banding and posterization mostly in the skies or similar smooth transitions of light/color. This usually happens when there is a change in the contrast, doge burn, adjust darkness with colors (example convert to B&W then lower the luminance of blue to darken skies)
I also tried using Silver efex pro and am getting the same effect but without the posterization - smooth transition but with faint color bands. I have to convert to a greyscale profile to get the color banding out.
-The weird thing is the photos look perfect in the RAW viewer, Lightroom, ACR, and even tried Aperture. All have the same issue/ everything is great until I export to photoshop to do more touch up.
Do I need to just convert to a grayscale profile once it is in PS and live with it? Is this common? I have been search quite a bit and cant find a similar problem on the web.
Files are from a Sony Alpha 850 in standard colors setting.
Mac Pro, and monitor is calibrated.
Here is a link to the photo (cropped),

Please download! the pic and then open in Photoshop to see the color banding.
It will look great in your browser window, it Has to be downloaded and viewed in photoshop with ProPhoto Color profile.
