Thanks for the tip, I'll try that. However, scanning at lower
resolutions would sometimes mean I cannot enlarge details so much, so I
would still prefer scanning at 600 dpi in some cases. Photo prints at
that time were pretty small, merely contact prints of the negatives.
We do not have most of the negatives anymore, but a contact print gives
almost the complete range of details of the negative. On some photos the
persons are too far away, and they can hardly be identified on the
print. But when scanned with a higher resolution, you will find a lot of
details, and suddenly you can clearly see their faces.
Lightzone seems to be pretty much like Darktable, which I use. Good idea
to try such a tool. You mean, adjusting the black and white levels AFTER
scanning with standard settings is ok?
