Blog #117 Infrared [IR Photography]
You might have heard of or even tried out infrared (IR) photography. There are three ways in which you can experiment with this technique. I will explain those below. First, I have blogged about or referenced this type of image making in previous blogs: Blog #29 & Blog #103. Let’s go back to Grade Seven Physics class for a moment. Electromagnetic radiation occurs naturally in the universe. The electromagnetic spectrum is measured in wavelengths of photons or light particles. The human eye can only detect a small portion of this spectrum (visible light such as the colours of the rainbow). Shorter wavelengths, not visual to humans (but are visual to some animals such as the mantis shrimp) include Ultraviolet, X-rays, Radio Waves, and Gamma Rays. Longer wavelengths include near and far field infrared light. These measure around 720nm (nanometers) or longer wavelengths. Some film and most camera sensors can see the IR wavelengths. A hot mirror is type of filter placed on your camera sensor that blocks UV & IR wavelengths and allows the visible (to our eyes) wavelengths pass through to hit the R/B/G circuits on the camera’s sensor.
If you like making black and white images and/or landscapes, you will love IR photography. The images below were made with a small 12mp Lumix converted by Kolarivision on a recent trip to Kitt Peak National Observatory in Tucson, Arizona, USA.
The light is always right.
