i gotta run now... but i'll send you tons of links on many different setups... the idea is basically the same.. add an additional servo somewhere.. and make it activate the button somehow.. (many techniques).....most digital cameras I know... you need to hold the button half way for some while, for it to focus.. and then press it harder, for the picture... this might be a problem... because it will be harder to do with a servo.. may be not... anyways.. that's how its done usualy..... just flip your switch on a radio.. and the camera shoots the pics... and you can also have another servo, to move the camera, for different angles....

anywayz.. i'll send some links later, after i come home...
