I calibrate my screen at night without any lights on at all. (That way I get no cast) I lower my screen brightness manually to compensate for the dark room I’m calibrating in. When finished I edit an image and print it off. I get consistent results that way.
Good advice Mr Printer. Even when editing on an iPad it’s important to turn off those things because they have them and edit in a darkened room at night with the device brightness set exactly where you know it’s correct for what would be I think called proofing brightness. I see some people that are very good, even brilliant photographers obviously editing in a room that’s too bright so the images they post look a bit too dark. Or is it the other way around 😂
