Quite strange to me is the white background of most easels. Just the opposite of the plate behind the film. That one is always black. I made prints with a white background and with a black background as well. To my opinion white could give halo as the light passes through the paper and returns from the backgrond.
So theoretically loss of sharpness.
I noticed that with a black background it takes more time. Is there another reason why it is better to have a white background?
I am new to the forum and this question is the reason why I am here. Hello to everyone!
