My DIY ringflash, see the workflow for more info and descriptions.
Hanimex CX-25 through the DIY umbrella diffuser from above. Hard to say the power level of the flash because it doesn't have any scale for now. ;) Background is the same white fabric that I used as a diffuser on the righflash and also with the umbrella. Shot with Nikon D2H + Nikkor 50mm/1.8D, flash connected to the camera thru the DIY multi flash sync box (for safe sync because the flash is with high trigger voltage).
