A fun little experience using a TI-83 calculator as an intervalometer triggering my Canon Digital Rebel XT to take 3 bracketed exposure images every 7 seconds. This takes place over an 1:15, which is how long it took to fill up a 2GB card shooting the lowest quality JPEG possible.
I used Photomatix Pro to batch process the HDR images, then compiled the video using Quicktime Pro. After that I brought the whole thing into After Effects and did some resizing, levels adjustments, added the music (which is Andrew Bird).
You will also notice that I there is a cat walking through the frame at the beginning, using the bathroom, and then walking up and bumping the camera. I wasn't paying attention and the cat moved my shot just a little bit, but I think the video turned out ok. Not bad for an early test. I'll have to do something a little more planned out at some point.
