Tom and I took a quick break after work today to try lofting my Canon camera up in the air. We used the Picavet that Tom constructed, and ran a simple uBASIC script that just took a snapshot every five seconds. We shot a total of about 120 shots, about one fourth of which were reasonably acceptable. We sent the camera up about three times with the camera adjusted three ways: the best seemed to be where the camera was adjusted to aim slightly down, below the horizon.
