>>2888621>is it normal to have to edit film scansYes.
If you find you're not getting much contrast on your black and white negs, you can also experiment with different films, exposure and development regimes too, to get more latitude out of them.
Pic related is a very contrasty film, with a blown out/blocked up section of sky.
Left is the raw scan, which I reduce contrast and lift shadows on, to get as flat an output as possible, and right is the plain exported jpeg after inverting, and the slight curve I added to it to get the blacks closer to black.
