Hack 25 Painless Infrared Photography

What kind of eerie world makes the sky go dark
and trees turn white? It's the stunningly beautiful
realm of infrared photography.

If you've ever tried
shooting and processing infrared film, you know what a pain in the
aperture it is to deal with. You have to load the camera in complete
darkness, guess wildly about the exposure settings, process the film,
and then cross your fingers that at least one or two shots turned out
the way you had hoped. The results could be stunning, but they came
at a painful price.

Digital photography has changed all that. Not only is persnickety
film handling a thing of the past, but you also now get to preview
your infrared images on the LCD monitor before taking the shot. And
the best part? They will look every bit as beautiful as their film
counterparts, as you can see in Figure 2-17, which
was shot with a Canon G1 digital
camera. This barn shot was taken at 1 p.m. Most photographers are
diving for cover at this time of daythat is, unless
they're shooting infrared.

Infrared photography deals with the spectrum of light that you
can't see but that your digital camera can. If you
buy a filter to eliminate the normal light rays and capture only the
infrared rays, you can add this look to your photographic bag of
tricks.

The first thing you'll notice in infrared
photography is that the blue sky goes dark and that most trees turn
very light. Glare is minimized, giving your
pictures an eerie clarity.

A popular
filter
for digicam infrared photography is the Hoya R72. If your camera accepts
filters, then go get an R72 at the camera store, attach it to your
camera, and look at a brightly lit scene in the LCD viewfinder.
You'll know right away if your camera is suitable
for this kind of shooting. You can test the
"infraredness" of your camera by
pointing a remote control toward the lens and seeing if the beam
registers the camera's LCD monitor (Figure 2-18).

What's interesting is that older digital cameras
often work better than newer models. Over the years, many camera
makers have added internal filtering to improve overall picture
quality (color, that is) that unfortunately hamstrings the
camera's infrared capability. For example, my Canon
G1 takes great infrared shots, but the G2, G3, and G5
don't perform nearly as well. This is a great
argument for hanging on to your older digicams, because you never
know what they'll be good for up the road.


Other older models that shoot great infrared shots include the
Nikon CoolPix 800 and 950,
Canon S10,
Olympus C-3000 series, and
Kodak DC 260.
Many others also work well. If you want to test a few cameras you
have on hand, try this. Line them up and activate their LCD monitors
in Record mode. Take a TV remote control and point it directly into
the lens of each camera while pressing any button, such as the
channel changer. The camera that displays the brightest light from
the remote on the LCD monitor is your leading candidate for infrared
photography.

Now, take your camera with a Hoya R72 filter out into the bright
sunlight. The best conditions for infrared shooting are a blue sky,
puffy clouds, and some trees in the landscape. Mount your camera on a
tripod and put it in Program mode. You need to steady the camera
because the shutter speeds will be very long, even in bright
sunlight, due to the density of the R72 filter.

Preview the scene in the LCD monitor and find a composition that best
shows off the drama of infrared. Some trees will turn white and
others won't, so you have to preview the scene to
see what's most dramatic. Take a few shots, and then
switch to B&W mode and take a few more. Later, while viewing the
pictures on your computer, you can decide which type you like better.
In Figure 2-19, the sky turns dark, the foliage
light. What kind of weird world is this?

That's all there is to it. Now, during the bright
midday sun, when other photographers refuse to go outside, you can
create dramatic, artistic images that will truly impress your
friends.
