When I am using the adjustment brush in ACR CC and I am trying to increase/decrease exposure and I use the brush it desaturates the color. I believe it is adding blue bc when I erase that move its like the brush is painting with yellow. I have selected new, moved exposure slider, then paint and that's what I get. i have not touched the color balance slider at all. What is going on and how can I fix. I really need to get moving on my editing. Thanks for your help!
