Filling gaps

Sometimes you want to be able to quickly fill in gaps in line art, for example to make flood-filling easier. Here is one way to do it, which works in most current graphics applications which support layers and selection operations. I use it both in Adobe Photoshop and in GIMP. more...

Calibrate Your Monitor

How can you be sure that the colors on your monitor are the same as the colors on other peoples' monitors? You can't! But if you want to come as close as you can, try calibrating it using these handy instructions!

Last updated September 2, 2010, because some of the information has become horribly outdated since the last time I touched it back in late 2005. There's probably a lot of other historical crap anyway but I can't be bothered to rewrite this page.

Also a very important note: These images only work correctly if they are displayed at a 1:1 pixel scale. Many combinations of newer monitors/operating systems/etc. — notably "high-DPI" or "Retina" displays — end up resampling images to display at a different pixel scale. This is fine for displaying most images, but these images will not work correctly when resampled. If you want to use these images for calibrating a display, please make sure they are displayed at 100% scale and that your monitor is set to a 1:1 pixel scale! (Or, better yet, use your OS's built-in display calibrator, because that is theoretically going to account for pixel scale issues.)
