This blog is devoted to the application of optical fibers in photography. I have several homemade (DIY) flash adapters channeling the light from the flash close to the lens. The technique can be used mainly for macro photography, but I will show examples for wide angle close focus techniques as well. The recent version is called fiberstrobe V3, hence the name of the blog is "fiberstrobe".

Fibers go underwater II.

After completing the first version of the ringflash adapter, it came to my mind that the same concept could be used also for close focus wide angle photography. Finally the strobe to subject distance can be very short in this case. I really liked the versatility of the Velcro, therefore I decided to use it to fix the fiber optics branches to the port shade. I glued the loop part to the shade and the hook part to the fiber branches. I sacrificed a diffuser of the strobe to attach the branches to the strobe. The inner part of the diffuser was covered by aluminium foil and the external side was painted black:

Here you can see the final set-up. I decided to create only a half-ring and omitted branches from the under part of the port shade. In this way I can avoid potential overexposure from sandy bottom :

  1. you've some very interesting DIY stuff here on your website! I read at that you're from Leipzig, Germany.. what a coincidence me too!
    What material are the arms cover made of?

  2. Hi,

    I've used loc-line modular hose system.
    I bought it on-line from here:
    but there must be a vendor also in Germany. It provides enough inside space for the fibers. In addition, these arms are flexible enough but hold the position after setting, which is critical for the proper aiming of the light.

    I will check your blog



  3. Hi Marcell,

    Great blog, this is a new whole idea.
    Do you going to mass production for this?
