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 light […]Read more "Ultraviolet photography"

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 them […]Read more "Putting my infrared filters to the test"
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 with […]Read more "Full spectrum camera conversion"
