These guys are doing legendary work with this effectively DIY scanner.

The Gugusse Compact

4K scanning, 8mm reels all the way up to 35mm reels.

Way better than buying some cheap junk scanner on amazon, or sending them off to a cheap film conversion place (where chances are they're likely doing the conversion are using the same amazon junk product anyway).

With the Gugusse, you have full control over scanning and processing, to ensure the best possible scan, meaning the best possible base for further restoration of the scan.
