Curves adjustment eyedropper tools are turning my image red
Hello,
I'm a Photoshop novice and I'm trying to correct the yellow color cast of an image by following the steps provided in a book. (Using the White Point tool in the Curves adjustment on the white part of the girl's dress)
As stated in the subject, my Curves adjustment is giving me unexpected results. Every time I try to use the white or gray eyedropper tool in the Curves menu and click on any area in the image, the entire image gets an extreme red cast. Oddly, the black eyedropper tool works fine. The same thing happens when I use the Levels adjustment.


I'm not sure what's wrong. I've tried to restart Photoshop and I've also reset all my tools. This is the first time Photoshop has given me any problems. Any help would be appreciated, thanks!
