The common mention of “ultraviolet” in photography is the use of ultraviolet (UV) filters, which specifically block UV light and allow visible light into the camera. 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”

St Philip’s Marsh
Not a very glamorous name, but there is a rail depot there and a good vantage point from St Philip’s Causeway. As it was sunny, I took this picture with my infrared DSLR.
Digital infrared
I’ve used infrared film quite a lot in the past, but hardly used my infrared DSLR for anything except astronomy. I once tested digital infrared, but this is the first time I’ve properly used it for photography. These assorted shots were taken over the past few days, whenever the sun came out. These pictures wereContinue reading “Digital infrared”
Canon EOS 600D (modified)
Released 2011 This 600D is just like the other one, except that it has been modified for full-spectrum astrophotography and is now sensitive to infra-red and ultraviolet light as well as visible light. The primary purpose is astrophotography, although I have also used it to make a video under the dim red safelight in myContinue reading “Canon EOS 600D (modified)”
Making a darkroom print
There are tons of excellent written guides about how to work in a photographic darkroom. There are even a few videos, but because digital cameras don’t really work well in almost total darkness, the videos are usually a bit rubbish. However, I have a DSLR which has been converted for full spectrum photography (infra-red andContinue reading “Making a darkroom print”
Busy bank holiday
I had a busy bank holiday weekend. I travelled around and shot three rolls and two sheets of film. I’ll try and break these photos down into distinct events. First there were a couple of test shots using my new Canon FD 200mm f/2.8 lens. The cranes stand in Bristol’s floating harbour and the other viewContinue reading “Busy bank holiday”
Infrared astrophotography – first “light”
It’s been quite cloudy recently so I’ve been clutching at any opportunity to make the most of clear skies. Last Tuesday it wasn’t forecast to be very clear at my dark site in Somerset but it was clear at my suburban address in Bristol. Light pollution round here is pretty bad and the sky oftenContinue reading “Infrared astrophotography – first “light””
Putting my infrared filters to the test
I now have three infrared filters 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”
Digital infrared on Troopers Hill
I’ve shot infrared film before but this is the first time I’ve tried digital infrared. I wrote recently that I had a DSLR converted to full-spectrum, primarily for astronomy use. With the right filter, it can also be used for infrared landscape photography. I decided to use an Astronomik 807nm IR-pass filter which is actuallyContinue reading “Digital infrared on Troopers Hill”
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”
