Good morning, I have a problem with flat shots taken with the asi air and my eos rp or with the 5dmk3. They all come out different from each other. Whether I do them automatically or set the times manually. They are slightly darker or slightly lighter and the histogram also confirms this. I tried with a white page of a tablet (light adjustment locked on manual) or with an overhead projector.
Is there any solution?
Has anyone had and then solved this problem?
