This is such a well-written article: it describes the impetus, it is researched, it has great examples both as code and as output, and it piques interest. In the late 1990's I contracted with an embedded software company to optimize a dithering algorithm for 8-bit MCUs that was used in most laser printers & copiers, and this paper is a really good overview.
Output dependent feedback is another good way to get creamy, evenly dispersed dots in highlight and shadow areas: https://levien.com/output_dependent_feedback.pdf
Pretty shameless Raph :P
> According to Wikipedia, “Dither is an intentionally applied form of noise used to randomize quantization error”, and is a technique not only limited to images. It is actually a technique used to this day on audio recordings […] Dithering as a digital signal processing technique is also used frequently in the digital control of physical systems. One example of this is in the control of hydraulic servo valves[1]; the…

I'm trying to figure out whether this is a compliment, a criticism, or both. When topics related to 2D graphics come up, there's a fair chance I've done some relevant work in the area. I plan to continue shamelessly hawking my results, as that's an important part of a research pipeline :)
It’s actually implemented in BitCam iOS app by icon factory: https://iconfactory.com/bc.html
And Emilio Vanni did a neat e-paper display experiment with it here: https://www.emiliovanni.com/atkinson-dithering-machine
Shameful tangential plug alert: My sideproject is a dithering-based image-to-pattern converter for plastic fuse beads (you know them, the ones you place on a platter and iron to fuse them together): https://www.beadifier.pro/
Does it make money? There a couple other simple apps I've considered writing to see if I can make a few side bucks.

Nice. A conceptually simple program made into a nice app. Well, I assume it's a nice app ;-) Does it make money? There a couple other simple apps I've considered writing to see if I can make a few side bucks.
