Dalantech, have you ever looked at this material? https://www.edmundoptics.eu/f/holographic-uv-diffusers/12652/ "Holographic Diffusers are used to control the diffuse area of illumination and increase transmission efficiency to greater than 90% from filament lamps, LEDs, arc lamps, and other sources...

Re: Diffusing a Macro Twin Flash

I've been playing around with configurations based on your recent blog post, seems moving the diffusion layers away from the flash bulb makes the biggest difference to the actual diffusion

Re: Diffusing a Macro Twin Flash

If your diffusers are bigger now are you still using the Gary Fong puffer plus as the final layer?

Re: Diffusing a Macro Twin Flash

Great work, looks like it's pretty much the final solution, how is it on bee faces, I think they are the challenge. One photographer I follow where I'm always interested by the diffusion is this Japanese Instagram feed. I expect the reason they can be so good it's that perhaps it's much less than 1x...

Re: Diffusing a Macro Twin Flash

So am I right in thinking your current lighting is Mt-26EX with 2 heads -> Drilled out diffuser cap as a bracket > layer of 1/4 stop silk > 1 cm gap > layer of 1/4 stop silk > Garry Fong puffer plus - > Subject. That's pretty close :) That is what I also have, basically copying your setup but also ...

Re: Beetles Eating Daisy Pollen

In my experience the Topaz denoise in sharpen does a decent job of smoothing the bokeh without affecting subject detail out which makes the subject pop a little more. I only ever use the Topaz sharpen as a final pass before publishing.

Re: Diffusing a Macro Twin Flash

Hi John, very interesting as always. How much do you think the size of your subject matters here, I notice you shoot smaller subjects at higher magnifications than I tend to, does the relative size of your diffusers make a lot of difference, whats your light like at 1x? Have you considered using som...
