today I went to work on some saved raw files from my Canon 7D. In bridge the thumbnail look ok, once opened in Camera Raw they have a marked magenta cast, the white balance is changed to custom and the magenta slide to +22. I have try to reset the settings to default but no change in the picture. Also change the setting to As Shot does not help. I cannot make meaningful adjustment. But once the picture is open in Photoshop it looks ok.
While in Camera Raw, press Ctrl+K (Cmd+K on a Mac) to bring up preferences, then uncheck Use graphics processor at the bottom. Does that fix the issue?
Thank you for your reply, unfortunately it does not make any difference
Then the most likely cause of the problem is a defective monitor profile.
Try setting it to sRGB (or Adobe RGB if you have a wide gamut monitor) as described here:
If that fixes the issue, you should calibrate your monitor with a hardware calibrator as soon as possible.
YAY, Thank you. Windows deleted the monitor profile from the color management system. Once reinstalled everything worked.
THANK YOU VERY MUCH
I know the graphics processor was not the solution to the original question, but that was the solution to my problem, thanks!
