Hi all. I’m using Panasonic S1r and valoi easy 120 as scanning setup. My camera has an option to make multiple shots and merging them which is called hi res. It produces 100mp files. Do you think it is better to scan using this option or just use 47mp files? Consider I have to crop a lot because I do scan 6x7 and 6x6 negatives
It uses pixel shift of course. I would certainly try it but you’ll need to make sure that you have a very, very solid setup as in order to succeed it is essentially moving the sensor by half the pixel pitch or multiples thereof. The pixel pitch of your camera is 4.3 µm, so just over 4/1000 of a millimetre. Still, it does the processing in camera which is good for the workflow but you will end up with very large files. If you find it works well maybe just save it for special images that you want to print large. You will need to be using a very good lens.
My setup is very solid because it lays down horizontally, not vertically. I tried it and noticed not so much of a difference. Also the file that comes out is huge and my MacBook Air M5 with 32gb ram needs to load for some second so I think I’ll stick with 47mp which is more than enough given I print A4 most of the time
Film does not have infinite resolution. Yes you will have a bigger file but you can’t get any more resolution than there was to begin with.
Yes, but with Medium Format even a 45MP sensor is not getting everything from a sharp negative on fine grain film. For a single shot with the short side of the sensor (5584 px) across the 56mm width of the film that equates to around 2600 ppi, about the same as the tested resolution of a highish end Epson Flatbed in real terms. Quite possibly enough though. For 35mm copying that figure rises to around 5900 ppi, which is plenty.
