This is a shot of a prehistoric Neolithic burial tomb in faux infra red that I took a while ago in the Dordogne. I used a R72 deep red filter over the lens to capture the upper frequencies normally associated with the infra red spectrum. Using this method, one has to compose and set the focus then apply the filter because once it’s on, it’s impossible to see through the lens! It only works on cameras with a weak anti-alias filter which will otherwise kill the effect. One day I will get an old Nikon body converted to IR to try more of this technique.
As an aside, these are some serious bits of stone to move and then cover in soil! Very clever (and fit) those prehistoric guys!.jpg "Neolithic tomb, Dordogne, France")
