Ultraviolet Video

After Matej Simonič successfully took some very good UV photos on 17 April 2010 in the siphon of Kompoljske caves, we returned on 27 February 2011 and made the first UV video shots of proteus and cave crustaceans.

We used light filters, lens filters and special glasses letting through only the UV and the violet component of light. Taking away the rest of the light spectrum the proteus nicely showed the spots where pigment was concentrated. The cave shrimps usually only showed the glittering pincers.
