I only wish the developers would put a change log on either here or their website like used to be included in the “Read Me” file that was distributed with the program before it moved to the app store. Be sure to play with the sharpen and contrast options (those were available in 1980s implementations, too) to chose the best dithering of a particular image. This app is useful for modern graphic artists either by combining its output with other layers in Photoshop (or other bitmap graphics programs that support layers) or preparing an image for print using this instead of a normal PostScript halftone. Tinrocket’s website has a direct comparison between this and Photoshop’s diffusion dither. For those not familiar with its output, the screen shot here on the app store is not the best example. To process an image with HyperDither, just drag & drop or copy & paste the image into the HyperDither’s main window. Specifically, HyperDither implements the Atkinson dithering matrix. HyperScan and the excellent Atkinson dithering routine were subsequently unavailable for many years-but not forgotten!įrom Tinrocket, award-winning creator of apps to inspire creativity: Waterlogue, This by Tinrocket, and Olli by Tinrocket.Īs someone who has had a Mac at home since the original 128k in 1984 and also used ThunderScan (which was where Bill’s algorithm was first used), i love this simple, well-designed app. HyperDither is an OS X image processing utility that converts color or grayscale images to 1 bit black & white using a sophisticated dithering routine. Turn your snapshots into mouthwatering illustrations. Transform your photos into dazzling mosaics. Add pointers, labels, descriptions, and commentary to your photos. Turn everyday moments into beautiful animations and drawings. Later, this graphics routine was implemented as an option in Apple’s HyperScan software, connecting early Macs to flatbed scanners, and nowhere else. Capture the essence of your photos in brilliant, liquid color and see the world like an artist. In the early 1980s, while developing the graphics technology for the first Macintosh, Bill Atkinson (HyperCard, QuickDraw, MacPaint) discovered a very elegant filter to convert greyscale image data for display on the Mac's 1-bit black-and-white screen. The visual effect produced by this technique creates rich, velvety tones, and is higher-quality than the “Diffusion Dither” method offered by Photoshop.
