The Camera Hunter
Do I Really Need
A Tripod?
Aspiring
wildlife photographers often overlook the importance of using
the one piece of gear most essential to consistently bringing
home trophy pictures of the critters of the Maine woods. Any
guesses as to what that is?
Those who said
the cursed tripod can cruise for the rest of this column. The
rest of you should pay careful attention to every word if
you're serious about camera hunting. And since the aim of this
column is so that you will learn to bring home better
pictures, there will be a test.
Ups And Downs
Let's first
explore the ups and downs of the cursed tripod. But wait. If
it's so essential for making great pictures, why say it's
cursed?
Hmmmm. Let me
count the ways. A leg jams as you set up in a hurry; a leg
loosens and slowly telescopes shorter and shorter; a tripod
doubles its weight as you carry it up Katahdin; the ground is
so mooshy you have to keep adjusting it to keep the camera
level; or you get so tangled in a "wait a minute"
bush that you miss the shot. Those are just some of the downs.
If you want to improve your wildlife photography, you need to
learn to deal with them.
Now let's look
at the ups. All good wildlife photographers use a tripod most
of the time and learn to love it as much as they hate it. Why
do they love their tripod? Partly it’s because the tripod
takes the weight of a heavy telephoto lens off their hands.
Partly it’s because they've learned to use their tripod to
make sharp pictures. And mostly because they know that their
opportunity with that moose, whitetail, hawk, or eagle will
not be wasted.
All sportsmen
and women know how it feels to waste a special chance. The
only difference with camera hunting is that you have a fuzzy
photograph to show when you tell your story of the one that
got away. The opportunity to bring home a real trophy is gone
forever - except in your memory.
And
if wildlife photography isn’t your thing? You can also use a
tripod to get better scenic photographs. In fact, the best
scenic photographers almost always use a tripod to get the
most depth in their photographs, something they can only
accomplish by using a slow shutter speed.
It's worth
noting that the comment I make most often when critiquing the
work of students at the nature photography courses I teach at
L. L. Bean is to "watch out for camera shake".
Camera shake ruins more nature photographs than anything,
including exposure errors.
Sometimes that
camera shake occurs from the use of a cheap tripod, which
we'll review in a moment. More often it occurs from not using
a tripod at all. You see, tripods aren't much fun to use,
especially at first. They restrict your freedom to just lift
the camera to your eye and fire.
Rule Of Thumb
An average
healthy person can hand hold a camera for a sharp photograph
if they use a shutter speed at least as fast, in part per
second, as the fraction made by the number 1 over the lens
length, in millimeters. Say you're using a 300mm lens. One
over 300 = 1/300th of a second. The newer electronic cameras
provide the s pecific
choice of 1/300th of a second among their shutter speeds. The
older mechanical cameras provide shutter speeds in increments
of 1/125th, 1/250th, 1/500th, 1/1000th of a second, so using
our rule of thumb we select a shutter speed of 1/500 of a
second to have a good chance at sharp pictures when hand
holding a 300mm telephoto lens. Unless you have one of the new
Canon IS (image stabilization) or Nikon VR (vibration
reduction) lenses, it’s wise to follow this rule. With the
new lenses, some can hand hold a 400mm telephoto at the
unbelievable shutter speed of 1/60th of a second
and get sharp results. But that’s a topic for a whole other
column.
Hunters know
that wildlife doesn't often show during the brightest parts of
the average Maine day, let alone at the brightest lit places.
The camera hunter similarly will have more success finding
targets either early in the morning or late in the day, and
usually at the edge of the forest where the light is less. In
short, you'll be lucky to find wildlife in light that allows a
shutter speed fast enough for hand holding your camera. The
answer? Use a sturdy tripod. Note that the key word is sturdy.
Sturdy Costs
Money
Sturdier
tripods do cost more. But the price of a good tripod pales
compared to the cost of the rest of your gear. Several
manufacturers sell tripod and head combinations for $150 to
$200 that adequately support up to 400mm lenses. A very good
tripod and head cost $500-1000, still a real bargain compared
to a telephoto
lens that can cost as much as $8000, even more! But pay less
than a $100 and you're kidding yourself.
The better
tripods have a head with a "quick release" device.
You screw a plate that comes with the tripod head into the
threaded hole on your telephoto lens or your camera body, and
the plate snaps into place "quick" when you set up.
The best ones have a locking mechanism to protect against the
plate releasing quickly at the wrong time, say when you snag
it on a limb hanging over a stream.
Catch yours in
the good light.
