This morning I was with a client for a product shoot, and have a weird color banding/artifact issue with ACR 7.1 Beta, it only shows in ACR at odd magnification levels. Look like it might be an issue with ACR and the video driver. The image opens just fine in Photoshop CS6. At first I really thought I had a weird case of CA, but that turned out to not be the case. Seems to be in the same family of display bug as the jaggies in the Liquify window
Camera: Nikon D800
Lens: Nikon 105mm Macro
System Software: Windows 7 Service Pack 1
ACR 7.1 Beta
Video: Intel HD4000 with lated patch applied.
Images showing this problem attached. I have blacked out the branding to cover the clients name
First image is at 13.1% magnification in ACR window, you can see the issue between the bottles
Second Image is at 25% magnification in ACR window and displays correctly.
Would be good to get this fixed as it was very confusing and I did at first play with the CA to try and correct the problem. Also confusing was it also looked like black clipping which clearly it was not
Working through the images from this shoot, the problem is images that have transitions from white or near white to black or near black, and it seems like it is a problem with how black clipping is displayed at odd magnifications like 14.1% (fit in view) in the ACR window.
I need to check with my client as he owns the image, pretty tight contract agreement. I am sure I can get permission and have a meeting with him this morning. If I get the green light will make available later today. What is the best way to get this to you. Adobe reached out to me as well and I am sure they will want a copy also.
I am having the same issues but with CS5. This only started when my PS6 Beta ran out and I started using cs5 again. One other point of interest is that the artifacts seem to act like clipping indicators and they can be changed by adjusting exposure controls. They disappear entirely if you turn on the highlight clipping indicator.
Some images I open have these artifacts no matter what magnifaction, some will display fine at 100% but these artifacts appear at other magnifications (50%, 33% etc.).
Just as an FYI, this issue is still there with the final release of ACR 7.1.
After some more testing, I am sure there problem is a display issue with black clipping at low magnification levels in ACR7.1. The issue shows only where there is an abrupt transition between a very bright area and an adjacent dark area and only at low image magnification levels - like 15%. Increase the magification to 25% and the problem vanishes; and so far seems limited to images produced by the D800. Similar images from my D3 do not show this problem - maybe something to do with the high pixel count of the D800?
Also the problem loooks to be confined to "Fit In View" select any of the preset magification levels and the problem goes away.
Eric, any luck with the file I sent you?
