Recently I found
myself in need of taking a photograph from about 20 feet away from the camera.
I have a Nikon F3 with the MD-4, which is a nice camera and I know Nikon
makes a remote trigger for it, but I also know that by shorting out the two
contacts at the very bottom of the MD-4 you can cause the shutter to trip,
and the process of doing this is so absurdly simple that it would be far
easer to make a trigger of my own than even consider calling B&H and
ordering one -- that's not even taking into consideration that I'm sure Nikon's
trigger release is an expensive piece of equipment. Luckily I live right
by a Radio Shack.
Total cost, around $2.00 depending on the length of the wire.
That's it.
When you're done, it should look like this:
Put it on a tripod, shoot yourself silly.
