Probably the easiest approach is get a better camera, but that's not always desirable. I got a real cheapie, and it doesn't have that problem. Basically, the problem is a tiny image sensor needs a super wide-angle lens to get a wide-enough image on a tiny sensor. You either increase the sensor size, or built a better lens. I notice people offering a software filter to add reverse distortion to the image in obs-studio, it's possible the same algorithms might work in other software. One of them tweaked a sharpness filter that came with the program, so you didn't have to figure out how to add an extra filter. It's damn hard to search for answers for a program called zoom, seeing as it uses the same name as a zoom lens. I wish programs wouldn't pick such generic, and inappropriate names. There's nothing zoomy about a chat program. -- uname -rsvp Linux 3.10.0-1160.36.2.el7.x86_64 #1 SMP Wed Jul 21 11:57:15 UTC 2021 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
