I recently got a Nikon Coolscan IV, a 35mm dedicated scanner. It came with an attachment to scan a 6-frame strip batch, so it's much faster than my slightly higher resolution Plustek 7400. The Nikon also has ICE which my Plustek didn't, so I'm able to scan even faster.

I don't find the 2900DPI of the Nikon to be a hindrance. This results in a roughly 11MP file, which is plenty of detail for me.

I tried to buy a dedicated film scanner and it was dead on arrival and I sent it back. So I decided that, since I rarely want much more than I get from my cheap flatbed, to give scanning with a dslr a shot again for the potential prints larger than 8x10. Got a nice light pad, tested it with my k3ii. This is more of a what if experiment, I've been wanting a light pad to look at negatives anyway.


I am including full-frame and crops, both after resizing both the larger larger 24mp k3ii, and the 2400p in height images I get from my scanner to a common 3000x2000. The dslr image is pixel shift (raw threapee -> tiff -> darktable jpeg, only because I'm more comfortable processing in DT). The scanner image is scanner -> tiff -> dt -> jpeg.


I can't seem to get the contrast right in the dslr image, perhaps I need to experiment with the tone curves more, I just applied a standard one meant for regular raw files. Otherwise I adjuste white balance and levels, and left it entirely unsharpened. Another thing to work on is getting the full negative in focus, I think the left side was slightly off. First scanner, then dslr. Any tips to improve pp for the dslr image are welcome, thanks!

edit: added another version after more tone curve tinkering and sharpening

I won't keep spamming this thread with my attempts, but after noticing that the invert module in darktable has an area selector for the film base, both white balance and tones improved greatly and were much easier to adjust.

I currently use an ancient Epson perfection 2400. I've managed to streamline the process somewhat by scanning a whole strip at a time then re-scanning the not-so-terrible pics individually, but it still takes a good chunk of an evening to scan due to the general slow scan speed at higher resolutions.

Re-scanning? What do you mean? Are you scanning prints, then re-scanning them?

Oh, you mean you use the first scan as a preview?

Yeah I scan the strip of 5 or 6 negatives at a time with default settings to preview them, then if any are noteworthy (i.e actually exposed properly/in focus ) I'll scan them individually and try to get the settings as best I can.
