I decided to start playing with Time Lapse photography again. I did a prior experiment (read about it here) using a DSLR and a remote timer switch. This time I used a point and shoot and some hacked firmware.
There is a program/firmware called CHDK. It is sort of a temporary extension to the firmware for Canon P&S cameras. It loads off of your memory card and then goes away when you restart your camera. It adds lots of interesting features, including scripting capability. The script I used allows you to set it to take an unlimited number of pictures at a regular interval. I chose to use a 1 second interval.
In the video, each frame is a different picture. The pictures were taken 1 second apart. The video is at 30 frames per second. That means that what you are watching is sped up to 30x speed. After reviewing the video, I think that speed works well when driving down reasonably straight roads, but it is way to fast for areas with turns like my neighborhood and my company's parking garage.
The camera, a Canon G9, actually has a bit in time lapse video mode. The problem is that it only shoots 640x480 and I don't think you can adjust the frame rate. Using CHDK, I can shoot at resolutions above HD and pick just about any frame rate that I want.
The video I posted is just a quick 720x480 rendering to get a feel for things. The actual frames are 5mp, so I could generate an HD version easily. I shot this pretty early in the morning, so it is pretty dark. I think it would work much better with more light.
Incidentally, the pause in the middle of the video is from me stopping to get gas.
You can see the video here. I'd love to hear feedback and suggestions.
