It is a little baffling to me. There’s a photo restoration group on Facebook that does free work. People are constantly submitting old photos and asking them to be colorized, and I’m a bit baffled. Especially when the submitter has no idea what the colors should be, such as eye color, or the uniform a person is wearing, or hair color. I’d much prefer a nice black and white restoration. But lots of people want color - something that came up years ago when film colorizing became a thing… :-/
My favorite future AI functions for photography are in creating perfect cutouts, including fly away hair, with perfect background color tint removal (thin or translucent objects always get some of the background color in them, and it’s hard to manually subtract that contamination, especially if the background is varied), and in color changing (manual color changing in Photoshop tends to give un-realistic monochrome looks). Demos in those areas have been stunning. Hoping for real world tools in not too long.
