When I posted this, my friend said she at first thought that yet ANOTHER common animal was showing fluorescence. I told her it was a lepus aeris.

This was produced with the same background light subtraction method that I used with the tree stump and Queen Anne's Lace previously. See those posts for technical details.

The lens was the Noflexar 35/3.5, the filters were the usual Tiffen 2E + BG38 2mm on the camera, and the Nemo's own filter. The Nemo had previously been modified by moving the white fluorescent band behind the filter.

Colors here were originally done using the setup for the gourd but I subsequently increased saturation.

The background has had artifacts (mainly dead pixels and line noise) removed.



This bunny has previously been captured in UV reflectography back here:

So is the copper oxidation the green or the blue? Or both?

I’m enjoying your fluorescence explorations.

I generally would not expect metal to fluoresce, also because of the shiny metal test, but oxidation, as suggested by Andrea may fluoresce, and probably does some.

The blue you got is interesting. A nice, deep blue.

I really doubt the copper is fluorescing. I think some could be oxidation and most (the bright colors) is old paint.
