… three cents per photo … 
Large prints for client. Some of my old photos were shot on 12MP sensor and need to be upscaled to print out to 72" wide.
Some were cropped with 1500px wide and needed to be upscaled to 10,000px wide for panorama print.
Cropping and upsizing, mainly wildlife images.
Gigapixel AI does a great job on old photos especially faces. I usually enlarge first, desaturate, adjust levels, repair scratches, tears etc. then I can colorize. I also use Photo AI for further refinement.
What app do you use to colorize?
Photoshop. Some adjustment is usually needed.
