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/
What an odd coincidence… I just acquired an "Inkplate" for my birthday (a recycled Kindle screen glued onto a board with an Arduino and wifi) and was in the process of looking for old 1bit art for it, stumbled across the term "ditherpunk" just last night. - https://inkplate.io artists: - https://unomoralez.com - https://www.instagram.com/mattisdovier/?hl=en - https://wiki.xxiivv.com/site/dinaisth.html I'm going to st…
It was nice to see a mention of Robert Ulichney. His 1987 book "Digital Halftoning" covers most of the ground that this blog post does, plus more.
A few years back, when TechShop still existed and was open, I made a present for my mother: a glass laser-etched and engraved with an image from her favorite comic. Because the comic was painted in a set of watercolors, this was going to be difficult. I ended up tracing the lines (for the deeper engraving) and then stomping on the color palette for the etching. Finally, I settled on different newspaper halftone sets for each "color."
It took several tries for it to come out alright. This might have saved me a few runs.
> 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…
