Misgellar logs aperture, shutter speed, film stock, and location per frame as you shoot a roll, then — once the lab hands back scans with no EXIF at all — matches each frame to its recorded shot and writes that metadata back into the image file. It’s solving a problem digital-first photo apps never have to think about, since a digital camera embeds that data automatically; film scans arrive blank. Free, with support for color, black-and-white, and redscale rolls.
