Hi one thing I been dealing with is my monitor or I don't know what it is but I notice that I edit every photo I like brightness and the white valance but if I turn off the computer and I check the images next time they are cold and dark I have iMac 27" and I calibrated with color Mo xrite my prints looks ok before so, now any time I want to use the image I edit I have to reedited again and that's all the time is that normal ?
