How to use a model airplane radio as a camera remote control
Pick up a cheap model airplane radio control unit, I
bought mine online from Tower
Hobbies for $65.
These things are rated for "out-of-sight" operation and will work at a distance
approaching a mile!
You'll get the transmitter, receiver, battery pack, on/off switch, and a couple of servos. I had a zippered nylon pouch and arranged the components to fit inside using a paint stirrer, a rubber band and a few nylon wire-ties. (I picked up some cloth camo tape from a local hunting store.)

Attach (screw or epoxy) a micro-switch (available from Radio Shack) to the servo and solder it's terminals to the shutter release cable. I did not want to cut up an expensive Nikon remote cable so I hunted for a "plug" that would fit the 'remote cable' socket on my Nikon camera. I found a generic 2-pin wire connector at a local hobby store (identical to the red battery connector in the above picture) which exactly fit the Nikon remote cable pins on the camera.
Next, shave down the white moving-thingy on top of the servo to form a cam (pictured below). As it rotates it presses against the micro-switch:

Here's the final setup with the camera mounted on a Bogen Magic-Arm with Super-Clamp:

I added the side strap to the transmitter to make it one hand operable.
Just a small flick of the thumb trips the shutter.
Use some leaves, sticks and plastic ivy to hide the camera itself.
