With the above image part of the blue sky shifts to red when softproofed. But it's in sRGB. Can you upload the same image in Adobe98? I couldn't reproduce the shift in the EagleLake shot off of Holmes site but XUN sent me a crop of the image that was in sRGB and I could see the banding when softproofing. I think the shifiting could be a color space issue.

Just for the record I tried redeveloping some problem images from the raw file in adobe, srgb and pro rgb and matching the working space with no noticable difference. Randy Laskody xun wang wrote:

I matched the same size image you sent me and compared the two...the one you sent me shifted, the Holmes image just dulled down a little. Any more of detailed look I'll be going blind. It's definitely not shifting. Have you tried downloading the Eagle image again and keeping it in Adobe and softproofing again? What platform are you on Windows or Mac?

I must have missed the portrait shot...have a link. John
