"UV light"

The same specimen on Fuji RTP film using the UV-Nikkor lens 105 mm f/4.5 and the FF Nikon filter (Wratten 18 A equivalent). Note the colour differentiation of the flower head. These details are not found in visible light.

UV images may also be acquired using digital techniques. For an updated review of digital UV and IR photography, read here.
