Trigger an External Flash with Some Fiber Optic Cable

After buying a Yongnuo flash and finding its wireless capabilities “hit and miss”, Marcell of fiberstrobe decided to try out something he saw on a forum: using a fiber optic cable as a sync cord. The Yongnuo YN460-II can function as an optical slave, so the basic idea is to channel light from your camera’s flash into the light sensor of the strobe. To solve the problem of light leakage, Marcell also created an accessory using LEGO bricks, cardboard, and duct tape to fox the fiber to the sensor and protect it from direct sunlight.

    Interesting idea. I may have a use for my Yongnuo’s afterall.

    That’s quite clever!  One of those why-didn’t-I-think-of-that sort of things.

    I have an SB-600 (no SU-4 mode), but if/when I buy a flash that can act as an optical slave, I will definitely try this before dropping another $70 on an AlienBees receiver.

    I think I’d use cardstock and some electrical tape, though.

    That’s one of the cludgiest, ghetto-est setups I have ever seen… and I have seen quite a few.

    Maybe just buy a real camera system?
