Another Darktable RAW development test. Darktable is a decent image sorting and RAW development tool. The Windows version could use some polishing but considering the price - free - there's not much to complain about. Here I used the cheesy watermark feature - something I never do so this time I did it. One feature that all RAW developers lack is digital branding. Digital branding would scan the bits of the RAW file, including its date and name, and generate an immutable cryptographic hash key with something like SHA-2 and insert it into the image EXIF with a new tag. Then no matter how much you tweak, edit, rename and otherwise hack copies of the image you could trivially find the original among the thousands of RAW files in your directories. Stable keys are the bee's knees. If I don't see something like this soon I may have to concoct my own program.
