UV fluorescence

I have started to play with this as a technique. Plenty of technical challenges, especially since the images are both stacked and HDR. This is a cluster of Spirea blossoms.

Wow, very cool. And what camera did you use? how to process the photo. Photoshop, CyberLink?

I use a Nikon D500, with a 105 macro lens. It is shot at f4 +/- one stop, shutter speed 20 seconds, ISO 200. This was done using Helicon Remote and the 20 images stacked in Focus. Other than adjusting the range of brightness, no editing was done. The 'glow' is due to the fact that in this this method the objects are emitting light, so it is like photographing light bulbs.
