    Hi,
    I thought I would share images of two Ranunculus spp I shot today - the meadow buttercup and the lesser celandine.

    Nice ones Boon! The UV+blue is actually UV+blue+green and the UV+blue+green rather UV+blue+green+red from what I can see (?)

    I'm using a full spectrum OM-D and the Coastal Optics 60mm f4 lens. These are shot with different filters, using a Xenon flash as the UV-rich light source. For the fluorescence images, I used 2 x 365nm Nichia-chip torches as light source as there is no/minimal visible light leak from these torches i.e. The light recorded is all fluorescence.

    Thanks Klaus. Yes the UV+blue should include that it also has a tiny amount of green. But the UV+blue/green does not let any red or IR through, but has definitely more blue and some green (compared to the first stack).
