I am an artist that is looking to get prints made of my paintings. I have tried this process my self and seem to have an issue matching my digital print to the original painting. My prints end up too dark and contrasty.
I photograph my paintings with a D3200 24.2 MP DSLR camera with dual soft box lights, so the image quality is good.
In the image I uploaded you will find a print beside the original painting. The print is darker than the original. If you look closely you can't see some blues, and reds are too bright. (I removed signature)
