Here are the plans that I drew up for my Wrap-around flash diffuser. It is designed for the Canon 430EX Speedlite, but can easily be altered to fit most any flash. Sample photos to follow below…Hope this will help those interested in macro photography and I hope my design can help someone else get better lighting in their images too.
I shoot with a Sigma 150mm f/2.8 Macro lens at the closest focus range of the lens in most cases. (About 9 inches +/- from the subject)
- Looking inside…I used a piece of aluminum foil placed in the center of the inside layer of vellum.
As for the slots in the vellum…when I was “tweaking” the diffuser I found that cutting the slots in the vellum allowed me to shoot with the flash at a lower power, which as we know means faster recycle time and longer battery life for the flash. The light coming through the slots is a “bounced” light, it tends to be softer and more pleasing.
So, the slots are to let more light through than the vellum allowed…and that light is also being reflected back into the top part of the diffuser by the piece of foil before exiting the slots in the vellum. So the foil is serving a dual purpose in that it stops the “hot spot” and bounces the light before it exits the vellum slots….This is my thinking behind this diffuser design and your mileage may vary….
