The wobbly pictures brings me back to my experience as a kid with hand-held photo scanners https://oldcomputer.info/pc/apscan/index.htm .

It was impossible (for me at least) to get a scan without shifting my hand position on the X-axis while also sliding the scanner down the picture.

Also, I seem to recall the scanner I used was only capable of outputting 1-bit dithered black and white pictures. This was late 80s/early 90s tech.
