The intimate secrets of a Lily, as extracted by the UV-Nikkor 105mm f/4.5 with Baader U filter, Broncolor studio flashes (with uncoated xenon tube), and the PrimaLuce Z5.

This is a 100% crop of the frame. 13 captures stacked in Zerene Stacker -- these flowers are highly phototropic thus move too much around to allow deeper stacks. Thus I needed to stop the lens down to f/16, which is far more than I usual prefer, f/5.6-f/8 being the normal options. The powerful studio flashes (1600 Ws) have no problem throwing sufficient UV light onto the subject, though, even at a distance of 1m used here.
