Description
Version 1.20.8 build 151 on Android 12
Scans of documents on regular white paper always have a blue film over them. I improve this by tweaking brightness and sometimes contrast. But the scale of the slider, max 5, is rather coarse. An increase in brightness of around .5 is already way too bright, almost a blank page. A fine-tuning slider, with a scale of 0 to 0.5 would be easier.
That said, I've been unable to find a way to get rid of the blue film in some other way. I want to retain true colors, the magic wand tool doesn't do this.

Research direction
No source file, test, or entry point is named. Start by locating the Android brightness and contrast slider implementation and the image-processing code that consumes its value; done means brightness can be adjusted in finer increments around 0 to 0.5 without breaking existing scans, with a test or manual scan confirming the result.
