This is less important in the digital days since UV is also blocked at the camera sensor. It was more important in the film days when too much UV lightContinue reading “Ultraviolet photography”

I now have three infrared filtersĀ and one ultraviolet-pass filter of varying specifications, for different purposes. Two of the IR filters are cheap, one of them was expensive and the UV-pass filter was found in a charity shop and I have no information about it. They all behave differently – so I wanted to test themContinue reading “Putting my infrared filters to the test”

Full spectrum camera conversion

This article is about exploring the world of light our eyes cannot see, using a modified digital SLR camera. I have a physics degree but I’m still finding my way with the practical applications of infrared and ultraviolet, so this article is mostly written from a theoretical point of view. Take everything I say withContinue reading “Full spectrum camera conversion”
