Edit Question
Title
Body
My usual method of 100% contrast and some brightness adjusting to tweak the cutoff point usually works reasonably well to clean up photos of small sub-circuits or equations for posting on E&R.SE, however sometimes it's not quite that great, like with this image: What other methods besides contrast (or instead of) can I use to give me a more consistent output? I'm expecting a fairly general answer, but I'll probably implement it in a script (that I can just dump files into) using ImageMagick and/or PIL (Python) so if you have anything specific to them it would be welcome. Ideally a better source image would be nice, but I occasionally use this on other folk's images to add some polish.
