Web Posterize |
As we all know, on the web, an image is only as good as its download time. 1 MB Picassos languish, while 18k Leroy Neimans thrive.

Web Posterize reduces any image to the 216 web-safe colors (aka Netscape palette, aka Netscape CLUT, aka 216 color cube), so that it looks as good on low- Desaturate & invertDesaturate removes all color from the image. Invert does just what you think it does (black is white, etc.) Brightness & contrastThese work just as you'd expect them to. You'll also notice how the color ramps shift as you adjust the controls. Contrast gives you a more compressed gradation, resulting in a more even shading over a smaller range of color. (Adjust that small range with the brightness control.) IconsThe sphere icon shows you foreground (highlight in red) and background (shadow in red). Color barsThese show how current settings affect the range of colors in the 216 color cube. Red, green and blue axes are shown. The grayscale ramp is a vector which runs from black to white. Red, green and blueHere you can adjust your image's foreground and background. You may subtract color from the foreground, or add color to the background. Tour topDownload now! | |||||

This filter would not be possible without the brilliant Martin "Arch" Archer, who first conceived the trick of posterizing at 6 levels to achieve web-safe images, and who generously shared the concept with this site's authors. | ||||
