I just saw this Black and Yellow Mud Dauber building nest on one of the granite pillars at my courtyard.
As the reflection of twin lights on the round body of the insect was quite harsh, I wanted to try new diffuser on my Canon MT-24EX macro twin light flash. I usually have Gary Fong Diffusers puffers on my twin lights. They are invaluable when used with Canon MP-E 65 f/2.8 1-5X Macro lens. But on Canon EF 100mm f/2.8 USM Macro they produce harsh highlights on glossy bodies of insects. I wanted to try some cheapo Nylon diffusers I procured at local photo dealers which were copy cats of Lumiquest diffusers. The result is here. I need still more experiments to come out with a better solution.
Apparently these diffusers are better, as you can see the harsh light is controlled considerably. But diffusers ate lot of power and flash was taking quite a bit (1-2secs) to recharge and be ready as compared to my puffer diffuser. As it made the twin light into a big soft box like light it might be producing a better fill.
