Ssh 'scanimage -x 210 -y 297 -resolution 300 > scan.ppm' This simple command runs an A4 sized scan at 300 dpi:
Finding that to be inconvenient I wrote a shell script on the Mac that runs scanimage via SSH. Since the Pi is headless I had to run scanimage via an SSH session. I connected the LiDE 30 and installed scanimage on the Pi. I happened to have a Raspberry Pi next to my desk which runs a webcam. It seemed crazy to buy VueScan for such an old scanner. "Easy Photo Scan" couldn't connect to the scanner and I also got the "Cannot find a driver" error message and a "Couldn't communicate with helper application".I have an ancient CanoScan LiDE 30. *: The only macOS app I found for Big Sur on the Epson website is called "Easy Photo Scan" (I use "Epson Scan" on High Sierra). What are good, consumer-level film scanners that are Big Sur compatible and can scan a variety of formats? I have been looking for articles comparing currently available scanners that would be able to scan the formats I shoot - 110, 16mm, 35mm half-frame, 35mm, 120, and 6x10, and have been struggling to find a review that wasn't mostly oriented towards 35mm film scanning or very expensive professional gear. So upgrading computers would also mean having to purchase a new scanner. However, I know that my scanner, Epson V500, doesn't work with macOS Big Sur as of May 2021* (I have tried on another computer running Big Sur) - and what good would a new computer be if I can't scan pictures with it? With Apple's recent rollout of their new iMac line, I have been considering upgrading my 2011 computer to something more modern.
