> Curiously, you're allowed to convert color to black and white, which in my opinion is not preserving the pixel-level integrity. An algorithm is making a guess at what level of black to convert a pixel to. In the sense of pixel integrity I had in mind, a b&w conversion wouldn't be a violation. Each output pixel would be directly effected by the corresponding input pixel (Bayer interpolation notwithstanding). Image data wouldn't be moved around from one region to another.
