* How to keep the camera in continuous shooting mode during the flight? Either you want to map a large area by moving around during the flight, or want to get the best images, it is best to shoot more pictures than needed with a large memory card, 4gb+. The continuous shooting mode is different for each camera, and not all cameras have it. [Check Camera Selection](http://publiclaboratory.org/wiki/camera-selection) Physically holding the shutter down in continuous shot mode is the easiest method, as described elow. Some cameras can be programmatically, such as Canons using the [Canon Hack Development Kit (CHDK)](http://chdk.wikia.com/wiki/CHDK). Some Canons can also also be triggered by infrared remote control codes, useful for stereo or near infrared camera pairs, along with [Stereo DataMaker](http://stereo.jpn.org/eng/sdm/index.htm). [Cris Benton and others use motors to trigger the camera.](https://www.flickr.com/photos/kap_cris/3154193529/) ####Super Simple- Holding Down the Shutter#### This is for use with the [PET Bottle Rig](http://publiclaboratory.org/wiki/pet-bottle-rubber-band-rig) Instead of using a balled up piece of tape, a pebble, or some other thing to hold down my camera's shutter, I've gone to using a knot. This makes it easy to hold in place, and makes setting it easier. I prefer [a rubber band](http://publiclaboratory.org/wiki/rubber-bands), but tape also holds it down. tape may be more useful for bulging, non rectangular cameras. My Canon SD1000 needs the [rubber band](http://publiclaboratory.org/wiki/rubber-bands) tripled up to hold it in place:

knot+rubberband+continuous shot = easier than CDHK
