I'm not sure I'd call Atkinson Dither "sophisticated" (the author does). In fact it's a mathematical error that happens to look very cool on certain material.

I'm not sure I'd call Atkinson Dither "sophisticated" (the author does). In fact it's a mathematical error that happens to look very cool on certain material. Sadly, the effect falls apart when scaled. You can craft a beautiful Atkinson dithered vibey image but you pretty much can't deliver it. Text it, put it on a web page, drop it into iMessage, Skype it -- nobody just delivers bits any more. It looks particularly awful when not at 100% zoom. Also the page's comparisons to Photoshop are misleading because you can do a Atkinson dither in Photoshop by setting the "Dither" slider to 75%. You'll probably find it looks better at 87.5% which throws away 1/8 of the error instead versus his 1/4. While I realize this violates the "if it's new to you..." rule, Atkinson dither has long since been strip-mined to the bone for blog posts and karma. Flickr did it as an April Fool's joke years ago. Frankly if there's a graphics tool that doesn't support it I'd be surprised.
