I process my raw files in Dpp4.5. then I go into Photoshop and do an levels adjustment. My white values in the mid 230 to mid 240.
When I try to lighten the Iris with curves do a quick mask and select inverse put it on its own layer. All looks fine as I lighten up the Iris. I see no lightening of the overall image. When I finish check some of my whites and they are in the 255 range.
What is going wrong. Thanks
