How is it done?
I made a bracket with a neck strap and a bungee cord around my back holds it against my chest. The camera attaches to the bracket with a tripod type bolt. I have used different methods to activate the shutter. First with just the in camera 10 second timer but the timing was too hard to catch just the right spot. Then I used a mouth operated switch. This was just a regular wired remote switch with a balloon over the switch to keep it dry. You can see it in the Close Up. It worked ok, but sucking on the switch gets old fast. The last pictures I took I used the wired remote switch and rubber banded it to the hand grip. I think this works the best so far. The wire from the switch to the camera is out of the picture and my hand covers the switch. If I get a wider view and the wire comes into view, it would be easy to PS the wire out of the frame.
