Comment:
I was just about to throw this rather old Parsnip (Pastinaca sativa) in the compost bin, and thought I would see if it reacted to UV. The results are quite interesting!

Technical details:
Nikon D850 with 105mm lens.

UVF: subject light painted with Convoy S2+.
15 seconds @ f/16, 200 ISO

The golden rule of UVP: never throw anything away unless it is photographed in UV/IR/UVIVF etc. first.

Is the colour reflecting the mental state of the root as it was going to end on the compost? :smile: :smile:

That's pretty amazing! It almost rivals your result with the oranges(?) (or maybe it was clementines?) from awhile ago.
