Question
First off, I know nothing about flashes.
I have an optar 152M flash that fits on top of the camera, and I want to trigger it manually.
The flash seems to have a contact where it fits onto the camera (or is that just to locate it?), and two contacts coming out as a cable.
Is it as simple as shorting the contacts together?
[EDIT] Thanks for the answers. I just had a look inside the flash, and it looks like it was stored in a pond at some point. It's now in the bin!
Answer
Yes, it is just that simple — short the contacts together to trigger it. This is the ISO standard design, and almost all hotshoe flashes follow it. Modern, fancier flashes will have additional pins used for per-manufacturer proprietary control, but usually shorting the center pin to the sides of the shoe will cause a manual flash even on these. as a lowest-common-factor "compatibility language".
