I would appreciate help making a device I can mount on my camera to sense the
flash, and wire it to an old technology underwater strobe to trigger it like a
camera sync. would normally do. Background: I do a lot of underwater
photography with 35mm film cameras with a direct wired flash strobe for
lighting. I would like to use it on my digital camera, but there is no sync.
connector provided for external flash units, like on my 35mm cameras. So, I
would like to build a small, simple circuit that would sense the flash output
from the digital camera flash and provide a momentary "closed circuit" for the
contacts on my external flash strobe. For packaging, the smaller the better.
Or is there something already on the market I can adapt?
Thanks in advance for any help.
