>>2842530> its just an effect of the shitty DSLR scanning setupHere's my scanning setup:
D90+macro extension tube+50mm f1.4 Nikkor AI lens with lens hood
I use a tablet as a light source in the background.
Pic related.
I have seen scans on the internet not using an extension tube or just using an ordinary kit lens but they have better scans. I don't know what I am doing wrong.
