35mm Scanning

rob1234 · 10-21-2012, 12:03 PM

Just for reference for future searches more than anything...

Just picked up an Epson 4870 from eBay for £40.

Here's my first quick and dirty test scan - no film holder, so propped up the film with a layer of medium-weight cardboard each side. Scanned at 4800dpi, resampled to 2400dpi in PS5, slight curves and USM mask, et voila:

ME, M20/4, T-Max 400, lab develop.

I bought it to scan 6x7, so for 35mm pretty happy! Full size on the click.

Don't waste your HD space with 4800dpi scans with that scanner. Just leave at 2400dpi and even that is exceeding its optical capabilities.

A very quick test shows that in my eyes, there is a very very marginal advantage to scanning at 4800dpi and then resampling. However, this is more likely down to my sharpening settings.

Eg:

100% from the 4800->2400dpi resampled shot:

100% from the 2400dpi scan:
