In this multispectral set there are two lessons learned, one on the application of a UV diffuser, and the other on IR illumination.

Mark,
Which diffuser did you use?
I will have to test the Lee 750, to see if I see similar. So far that would be the best diffuser.

I used a Roscolux #163. To be clear, the diffuser worked well enough for the UV image, but the loss of UV intensity for exciting fluorescence was unacceptable. And in the end it's not really much of a benefit to me to have the UV source diffused for UVIVF images, pointedly because I've become accustomed to light painting my subjects anyway. So... good for UV images - not so good for UVIVF images.
