Photographer Váncsa Domokos created a neat do-it-yourself camera accessory that uses optical fibers to control the direction and intensity of a flash unit’s light. Instead of having light come directly out of the flash unit, the accessory redirects it through a thick bundle of optical fibers, allowing you to point the light in any direction — and in different directions if you’d like.
If Doctor Octopus were to design a DIY flash accessory, it might look a little something like this. German microbiologist Marcell Nikolausz has been experimenting with using fiber optics to split a single flash unit’s light into multiple light sources. Optical fibers are threaded through Gorillapod-style Loc-Line channels, allowing flexible and stable positioning of the light sources. Each individual light source can be controlled using various modifiers (e.g. diffusers, gels, etc..), changing their quality and intensity.

No, this isn’t some advanced beam weapon from a sci-fi flick. It’s actually a do-it-yourself ring flash created using 150 optical fibers, with one end wrapped over the pop-up flash of the DSLR and the other end spitting out the photons in a ring-shape. If you want to learn how to make your own, here’s an in-depth writeup on how this was constructed.
