Unless you know that your camera's
resolution is first-rate, skip the scenic shots and get
close to the action. Close-ups are always more interesting
anyway.

How to get around the limitations of typical digital
cameras

Your new digital camera isn't your
father's Minolta. If you treat your new high-tech
picture-taker as if it were a film camera, you might be
disappointed with the results. Digital cameras have special
talents -- they produce pictures that don't need to be
sent out to be developed and that can be viewed on
practically any computer screen -- but they also have a few
big limitations. Avoiding these digital camera traps can
help you get better pictures immediately.
Trap 1: Shooting into the light.
Most digital cameras are wimps when they try to capture
excessively bright scenes. Their tiny image sensors get
overwhelmed, and the portions of the picture hit by the
excessive light aren't just too bright; they're
actually washed out completely -- what photo technicians
call "blown out." They contain no detail at
all.
Film, on the other hand, is much more
forgiving. The newest digital cameras show signs of
improvements, but a good general rule is to avoid shooting
into the light in any brightly lit scene. Be especially
wary of backlit scenes, in which sunlight or bright
interior light can wash out part of the image or fool the
camera into darkening the rest of the image.
If you're taking pictures outside in
bright sunlight without any shade, try to follow the old
advice about keeping the sun over your left shoulder. This
will force shadows to fall to the right, where most people
find them more natural. (Most of us are right eyed as well
as right handed, and we tend to prefer right-side
shadows.)
If you can avoid bright sun, be sure to
seek out the shade when taking pictures outdoors. But find
real shade, not the partial shade of small trees or short
awnings. Your camera will do a better job if it doesn't
have to cope with areas of bright sun in a mostly shady
scene.
Trap 2: Taking distant scenes.
Most digital cameras can't capture as much detail as
film cameras can. This measurement of a camera's
ability to delineate every speck and whisker is called
"resolution." Unless you know that your
camera's resolution is first-rate -- 4 megabytes or
more -- skip the scenic shots and get close to the action.
Close-ups are always more interesting anyway.
The lazy way to get closer is to zoom
in. This never works as well as cozying up to your subject,
because only by getting close can you perform that miracle
of photography, bringing the viewer into the picture. Try
taking your pictures from no more than four feet away. When
you feel comfortable at that range, try getting even
closer. Take a few test shots to see how close your camera
can focus. You'll probably find you can get much closer
than you ever thought possible.
Trap 3: Erasing the evidence.
Film cameras take pictures that stick around. You can
usually pull the negatives out of their sleeves and have
more prints made. But digital cameras store all their
images as files that can be inadvertently deleted.
Here's how to protect yourself: Never allow your
computer to delete pictures as they're taken off your
camera or memory card. Wait until you've seen them and
saved copies of the pictures you want to keep. Then, and
only then, should you delete the originals from the camera
or from its storage cards.
My technique is simple enough to
recommend to others. First, I connect my camera to my
computer or I snap my camera's memory card into my
computer's card reader. (I use both methods.) A pop-up
window asks me to confirm the copying process. The pop-up
window also asks if I want the computer to delete the
pictures after they are transferred. I always respond with
a "No."
After the pictures are copied to my
computer, I look at all of them, one by one. I make copies
of all the pictures that are good enough to keep, being
very generous in my judgment. (The only ones I reject are
bozo pictures such as shots of the floor when I set off the
camera inadvertently or shots that are totally dark, taken
with the lens cap on. I keep all the rest.)
Then I delete the originals in the
camera's memory card.
Trap 4: The dog ate my battery
and other tales of low-voltage woe. The batteries in film
cameras tend to last forever and a day. The batteries in
digital cameras might last only a few hours. If you're
serious about digital photography, buy TWO spare batteries
and keep the camera's main battery and your spares
charged up.
Nickel cadmium cells, the most common
kind of rechargeable batteries, work better if you charge
them only after they're completely drained. But if your
camera uses nickel-metal hydride batteries, you can
recharge them even if they're only partly drained.
One last tip: If your camera uses
rechargeable AA cells -- the kind everybody used to call
"penlight batteries" -- you can keep some
alkaline AA cells around for emergencies. They should stay
in good condition for a couple of years.
