I just found a picture again I took years ago, and I'm wondering what's happened ever since then - I hope this is the right place to ask!
I sat on my swivel chair and spun a few times, while taking this picture of my CRT display at a random moment.
The digital camera I used was (according to EXIF, I don't remember anymore...) a Nikon E4600.
While I've heard of distortions due to a rolling shutter, I would expect it to affect the whole picture, not only the desktop screen.
What's going on there?
