Digital Infrared Photography
I have become intrigued by the possibilities of digital infrared photography. Infrared light (IR) is all around us but cannot be seen, although it is possible to adapt digital cameras to capture IR. There are two methods - the easiest and cheapest is to attach an infrared filter to the lens, which cuts out visible and UV light but allows IR through to the sensor. The drawbacks are that obtaining the correct exposure is a matter of trial and error, and long exposures are required - generally 20 seconds plus.
The second method is to have a digital camera converted to IR, which means modifying the sensor to capture only IR. The advantage is that the camera can then be used in the usual manner with normal exposure readings. The disadvantages are the cost compared to a filter, and once converted the camera can only be used for IR.
I first experimented using a filter, and became fascinated by the effects, so eventually I had a Nikon D200 converted to IR. I have included a few IR shots in the Simply Monochrome Gallery and will be adding more over time.
