Take the Shot
The early morning or late afternoon hours are the best times to shoot infrared photos. You can??™t
shoot at night, of course, because there??™s little or no infrared light available to expose your
picture. You??™ll find out very quickly that infrared photography is dramatically different than
visible light photography. The most important difference, of course, is that an infrared filter
blocks nearly all of the visible light coming into the camera.
CHAPTER 8: Push Your Camera to Its Limits 165
The lack of visible light means that exposure times are much longer than usual. You might
find your camera exposing a picture for half second or more in broad daylight??”which means
that a tripod is essential.
There??™s so little light that you may run into another problem: it??™s hard to see through the lens.
As a result, the camera??™s LCD display is very nearly useless for framing your shot. If your digital
camera has a window-style optical viewfinder that doesn??™t get its information from the lens, you
can use it to frame the scene instead. Alternatively, you can line up your scene with no filter in
place and then screw the filter onto the lens and take the picture. Obviously, you??™ll need to use
a tripod.
Edit Your Pictures
When you get the images back to the computer, you may find that the infrared shots have a
relatively narrow dynamic range.
