Description

Half 'n Half: IR - Full SpectrumOnce upon a time, in a Galaxy far, far away - the garden at my cottage in Scotland, actually - I discovered that if I placed a Cokin 3 stop neutral density filter (plastic rather than glass support medium) in front of the lens of my full spectrum converted camera (Canon 40D) the neutral density filter blocked visible light, as it should, but did not block infrared light. The result was that unless the incoming light was particularly colourful or had little infrared light in it, then the final image looked like an infrared shot. As blue skies are lacking infrared light so they can remain blue in these images, and such shots have a characteristic look, see here for some recent examples of what I now call the Okavanga Technique ==>
I thought it might be fun to use, instead of a full ND filter, a graduated filter whereby part of the light would be subjected to 3 stops blocking of visible light with a gradual diminution of the effect alo
