- 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. After the flight sort locally or with mapmill.org to select the best images for making the map.
The continuous shooting mode is different for each camera but most are the same. Some cameras can be programmatically controlled such as Canon(CHDK), but the shutter button can also be held down physically to keep the camera in the mode.
