scanner - How can I "scan" an image at a set DPI using a camera? - Super User
Detailed Setting Instructions
Canon Knowledge Base - Adjusting Color Mode and Output (Scan) Resolution (5600F, LiDE 100, LiDE 200)
How should I set my scan settings to digitize over 1,000 photos using Epson Perfection V600? 1200 vs 600 DPI makes a huge difference, but takes up a lot more space. : r/DataHoarder
