Thanks for sharing! I personally use Darktable and negadoctor, but honestly this doesn’t look too complicated either. Sometimes it’s very hard to get consistent results. Usually there’s not one set of settings to gets me satisfying results for all photos on a roll (usually due to tinted lighting, under/overexposure, etc). I tried using the first part of the roll, where there’s usually a fully exposed and fully unexposed part, for tuning the initial values. But this also doesn’t always deliver consistent results. Usually it’s a lot of back and forth between different photos.
