Infrared photography appears to be gaining exposure and popularity around the world including Australia.

It is common that most people modify their ageing, discontinued and lesser-used digital cameras for infrared photography. Every now and then, I receive such a digital camera to be modified. Here is a discontinued Canon PowerShot G5 for infrared modification received at work. I dismantled the camera, removed the CCD imager, and the bandpass filter (glass with blue tint) then replaced the latter with a clean infrared filter. Like with all such modifications, all surfaces had to be painstakingly cleaned of large dust particles.

I also re-modified my Canon PowerShot SX120IS by removing the infrared filter I had previously fitted inside it. Now without the infrared filter, the camera has become a full-spectrum camera. It “sees” from ultraviolet to infrared. I carefully glued a 43mm-58mm step-up ring on the front of the lens so that 58mm-diameter infrared filters can be easily used on the camera.

I now have 3 infrared filters at different transmission frequencies, one at 680nm, one at 720nm, and one at 950nm.
