Let's cut to the chase, Shooting in IR is amazingly easy to do, but only after you have learned some of the basics. And especially after you have learned to use the camera equipment that you own to shoot in IR. There are quite a number of variables for you to learn, but you will easily get down to the brass tacks of your specific gear.
Hopefully you will get a good general working knowledge about IR from these posts, but you will find that you only need a small portion of what we will talk about in your day to day shooting.
Back to the title.... it really is "The Light".
Light in the Infrared Wavelength Spectrum is just above the Reds of the Visible Spectrum that we humans can see. We are not able to see the IR Wavelenghts above visible Red, or Ultra Violet below the blues and purples. The following graphic will give you an idea of the Visible colors that we can see, as well as wavelengths on either side of the Visible Light that we are unable to see with our eyes.

It helps to have a graphical representation of the light that is always around us, even if most of us non-scientists don't really understand the technicals of what it is all about. The important fact is IR is there, it exists, and it is the target of our IR Photography efforts.
Next Post we will discuss how you are going to go about capturing this "Invisible Light" and put it into a form that the human eye can see and appreciate.
Really facinating stuff, this IR Light.
