When I have a dump of photos to talk about on a given topic.

Upscayl: AI image resolution increase-er

Upscayl is not capable of adding detail especially in challenging lighting, so this photo is unmodified
Upscayl is a FOSS project that runs as an Electron application and utilizes a dGPU and machine learning to increase the resolution of photos, adding geometry via AI. I tried it out this weekend on a few old Facebook photos, and the results were interesting.
