Irfilter

The Hack-a-Day peeps dig into forums and other nooks and crannies of the internet and find exceedingly cool projects like this one. If you’re into astro-photography, you should check this out. You can make your camera return to normal functions by mounting an ir filter on the front of the camera, so you’ll be alright there. Of course, I’m curious about what portraiture would look like without one of these filters! [via] – Link
