I want to do photography by radio control with my 5D, so I bought a Dunecam ( http://www.dunehaven.com/dunecam.htm )
This has four different ways to release the shutter, so I wasn't expecting difficulty.
First choice would be CHDK I've got a suitable USB connector and the Dunecam can raise a +5v signal down it for this purpose. But CHDK is not available for the 5D: http://grandag.nm.ru/hdk/autobuild/download.htm
Or did I overlook something?
Second choice would be IR (I've got a suitable IR LED). But it seems that the 5D doesn't have IR release, without spending $$$ in an LC5
Or did I overlook something here?
Third choice is a switch (the Dunecam has a relay and can close a circuit), but I would have to construct a custom cable for that...
The fourth choice is to rig a servo to press the shutter button. I would rather avoid that if I can...
Any help would be appreciated.
