There are ways to try to compensate for the uneven exposure & that's what I've tried to build into the main script.
The process requires an image that has a gradient which will let us darken the central area of the image.
We've not mentioned exiftool yet, so I'll do that now & then we'll work through the concepts needed to turn a set of termux command line tools into a reasonably friendly system for processing a RAW photo
These are the settings/options that I have used. You might like then, want to change them or want to experiment & extend them. That's all good!
We'll work
The aim of this next part of the setup is to create a set of locations for settings to be stored as files, so that we can pick the ones that we want & apply them to the image that we want to process.
