Pixel Joint Forum: Perfect dithering

Message

   I don't seem to understand dithering, I mean I can make the checker board stuff. But what I am talking about is people who so flawlessly dither so that with little colours you can get some amazing looks, I mostly see stuff like this in the sky. Here is an example.

If anyone could explain the mechanics I would be very grateful.

	That there, is a dither approximating Ordered dithering; the application of a treshold matrix (as in contrast to error-diffusion performed by algorithms as Floyd-Steinberg). More simply, one is producing a symmetrical pattern with different proportions of two colors. These patterns will/can then seamlessly transition between areas with different proportions over any distance (depending on the colors that one is trying to simulate). Yeah, it's kinda confusing when explaining the technical nature of it :/ ... just study, practice and try to develop a natural feeling for it.
