Awesome job! This makes me a bit envious. I am hobbyist colorizer [1] who did it the old school way (with tools like Affinity Photo and lot of manual work). I tried de-oldify and other tools but I justified my work thinking how horrible they were but pallette.fm is way too good. Not sure if I would find the motivation to restore old photos anymore. Glad that this was just a small hobby for me and I had just started learning the ropes.
But I would be dead scared if I was a professional[2] who did this full-time. Is this what AI taking your job feels like?
