Camera Selection
What kind of camera works best for balloon/kite mapping?
Technically, any camera will work for balloon and kite mapping, but compact cameras in the "point-and-shoot" class are the right size & weight for balloons and kites, and are cheap. Phones with good cameras can also work, although in turbulent conditions there may be some motion blur problems.
Most cheap consumer cameras have good enough resolution, though >2 megapixels, and closer to 8-12 is best. It's best to choose a lighter camera (< 1/4 pound or 150 grams). An older, used camera is a good option, as it is possible to lose or damage cameras if something goes wrong.
Quick answer: many PLOTS mappers have been using the Canon A495, which has the following properties:
- can be bought for < $60 new
- uses AA batteries
- 10 megapixels
- can be used with continuous mode (see below) or CHDK
- durable and reasonably light (~250g)
Continuous Mode
You will need a camera that can do continuous shooting (or "continuous drive"), or you will have to add an external shutter trigger (see the camera trigger page).
