Invisible Light

A couple weeks ago I set out to create invisible light. The idea was that I could light my subject noninvasively. For example, if there was a talk or a ceremony of some sort, I could light the subject without adding any light that would be seen by the audience. How? Infrared light.

Infrared light is in a light spectrum that is invisible to the human eye. However, it is not invisible to electronics that do not have an IR filter. So while the human eye might not see this light, cheap cell phones will:

Note that my DSLR has an IR filter, but not a very good one. That’s why it is picking up some infrared light (which is why it is somewhat visible from the LEDs themselves in the image above.) I bought 50 of the brightest infrared (IR) LEDs off along with all the other necessary small electronics pieces I needed for this project with the hopes of exploring IR portraiture. To my dismay, these lights are far too dim for portraiture…

Also note that there is no IR filter on the lens in these shots — just what is already in my Nikon D3000.

    Dude Hai that’s so impressive and you’re so cool, even if the infrareds don’t do portraiture. I think you’re awesome. just thought I’d throw that out there.
