It's currently way slow, but I suspect there is substantial room for improvement there. Wrangling NEF files has proven more …
Inspired by this post at DataGenetics,, I implemented a quick-and-dirty script in python to test it out. The first takes an input image and iterates over it pixel by pixel, splitting it into two output images. Ideally, the outputs are randomly assigned, so it is impossible to recover the original …

I'm using Linux Mint 15 ("Olivia") for my pypeline development - and ran into a little difficulty

Since I plan on taking quite a few night sky pictures, I'd like to automate the process as much as possible. The project is hosted on github here. Right now it's essentially empty, but eventually features I'd like it to have:
