InfraRed Austin FAQ
Welcome to the InfraRed Austin FAQ. There are a lot of questions
about infrared photgraphy and related topics and we even have a few
answers...
What is Infrared photography?
Infrared photography is the art (and/or science) of taking visible
photos of the light reflected in the infrared ("below red")
portion of the spectrum
Huh? What is Infrared light?
Infrared light is electromagnetic radiation (as is visible light),
but is of a low enough energy that you cannot see it. There are
two main ranges of infrared, near-infrared (close to the visible
spectrum which is viewable by some cameras) and far infrared (usually
perceved as heat).
So, how are you taking photos of invisible light?
By using a infrared filter which blocks out almost all visible
light and allows only infrared to get to the film or CCD.
I thought infrared filters blocked infrared light.
That's the other type of infrared filter. Terminology
can be a pain in the butt.
So, why are you taking photos in infrared?
Because is allows different details to show up that may not be
visible under visible light. It also allows for some really cool
effects. Grass and leaves reflect very brightly in infrared and
appear white, whereas trunks and branches reflect very little and
therefore appear dark. People's eyes also look really odd.
And because I can.
I thought infrared photos were Black & White. Most of yours
are in color. What's with that?
I use a digital camera and my infrared photos actually start as
a very odd looking "redscale" (various shades of red,
ranging from red to black). Using Photoshop, I convert most of them
to Black & White (grayscale) and then manually "tint"
them.
What about night vision goggles and infrared stuff like
that?
That's actually the "far-infrared" or heat portion
of the spectrum being viewed. My camera cannot detect far-infrared,
but it can pick-up near infrared (like your TV remote).
