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".

Project failed (I)

I think it's also important to show not just the successful projects but also the complete failures. White background flower close-up and macro photos are on my list for a long time. The standard technique is to lit the white background with one external strobe while illuminating the main subject with a second one. So minimum two external strobes are required. I have two units but they don't communicate with each other and actually my manual yongnuo is behaving very unreliable recently. So I wanted to solve this challenge with one strobe only. I thought that I can modify the V3 unit with 4 arms, in a way that 2 arms illuminate the background and two provides light for the subject. So this is the set-up with a special background unit:

It looks cool, isn't it? The problem is that it doesn't work in a way I wanted. The background is not homogenously lit and way under exposed. You can see the problem below:

 The direction of the light is not good, there is a hot spot in the upper part and the background in the homogenous area is not white but grey. These are the best photos I could achieve (and far from the standard I wanted to achieve):

Conclusion: I have to invest into a second flash soon.
