Screenshot Helper

Screenshot Helper shows a full screen window with a solid color or a desktop picture so that you can take clean screenshots without having irrelevant windows and desktop icons in the background. The easiest way to get a clean desktop for screenshots on Mac OS X is to create a brand-new user account and log in as a brand-new user. But if you need to use your own user account for whatever reason and you have a messy desktop like I do, you can use this application to hide the actual desktop and take clean screenshots. You can make the entire screen black, white, red, green, or blue to check dead or stuck pixels on your LCD screen, or for a blue or green screen chroma key.
