IEEE Spectrum discovers
the joy of hackable devices
using the Canon Hack Development Kit.
"Most camera traps use an infrared motion detector, but a
CHDK-enhanced camera can itself detect motion. Van Barel's script gives you
control of such things as the delay between the motion and the shot and
whether the focus is fixed or variable. Without any tuning at all of the
script's parameters, I was able to get some fascinating photos of birds
cavorting around the family bird feeder. Others have used similar scripts
to produce some stunning photographs of lightning.
