I had an idea that I would like to build a UAV that is made just for taking aerial photos perhaps even just directly below the plane. So I already know the hardware needed for a UAV but I am wondering what kind kinds of cameras people have used that have great clarity and small form factor. Also one piece of hardware that im not real familiar with is a trigger that can be used to "snap" the images whether its one that can be programmed to take pictures at certain "points" or via RC. I would like one that could be programmed somehow because I would like to use it as a way of mapping small areas ie farm field, junk yards, etc. Any ideas would be greatly appreciated.
