Infrared Vision: October 2009
In October, I learned that digital cameras pick up infrared light – light in a color we can’t see. This blew my mind. It still does. I discovered I could make a homemade infrared filter out of nothing but a shortened cardboard paper towel tube and a couple layers of exposed film. I had plenty of that lying around in film school! It was opaque to my eye, but let only infrared light pass through to the camera lens.
The following photos are a sample of my experimentation with a consumer digital camera (a Canon PowerShot) and the homemade filter, getting the lens to focus correctly through it, capturing the light in the best ways possible, and slowly gaining proficiency. 10/4/2009 – 10/6/2009.
