… on dithering

I have previously posted about dithering, which is a beautiful aesthetic that emerged from a technical limitation. Last week, while browsing RSS feeds, I came across the news that Bill Atkinson had passed away. In addition to his numerous accolades in Mac OS and UX design, Bill created his dithering algorithm, known as Atkinson Dithering, which was developed for the original Macintosh (MacPaint). This post serves as a collection of other intriguing resources and articles related to the topic.

Image Dithering: Eleven Algorithms and Source Code

Dithering is still a surprisingly applicable technique, not just for practical reasons (such as preparing a full-color image for output on a non-color printer), but for artistic reasons as well. Dithering also has applications in web design, where it is a useful technique for reducing images with high color counts to lower color counts, reducing file size (and bandwidth) without harming quality. It also has uses when reducing 48 or 64bpp RAW-format digital photos to 24bpp RGB for editing.
