As this series
indicates, ambient light alone (Photo A, top) is not
always ideal. Fill-in flash (Photo B, bottom) can be
useful for moderating contrast and convenient when attached
to a bracket.

Every avid outdoor photographer
has discovered some key accessories which help to solve problems in
the field. Whether through trial and error, from reading about photography,
or with the guidance of a workshop instructor, these soon become an
integral part of his or her arsenal. Helping to overcome technical difficulties,
the best devices are useful for problem solving or preventing frustration.
While creative vision is essential in the photographic process, the
following accessories can help to assure greater technical achievement
or increased convenience in the field.
1. A lightweight/rigid
support. Some photographers are not yet convinced that a 3
to 4 lb carbon-fiber tripod is suitable for serious photography. They
firmly believe that “only mass provides stability” and will
buy the heaviest tripod they can find. If you fall into that category--or
if you routinely photograph wildlife with a 13 lb lens like a 400mm
f/2.8 telephoto--you may wish to stick with a massive tripod.
However, for many other types
of photo equipment, the popular carbon-fiber models--light in weight
but rigid--are worth considering. Because they are more portable, they
are more likely to see frequent use, increasing their potential value
as a useful accessory. Before buying one, do check the specifications
as to the amount of weight each model is capable of supporting. If you
frequently shoot with a 500mm f/4 telephoto, don’t pick the model
that’s intended for backpackers with compact camera equipment.
Like any tripod, the carbon-fiber
models provide the most stable platform for camera equipment when used
intelligently. Extending the center post more than a few inches creates
a monopod on three legs, so it is not generally recommended. During days
with strong wind gusts, there is less risk of equipment shake if you shoot
from an even lower level; extend only the top section of the legs. In
ground level photography, extending all of the legs reduces stability;
it also increases the risk of damage to the tripod. For maximum security,
extend only the top section (with the widest diameter tubes) when using
this shooting technique.

A reflector panel (Photo C) is a fine alternative to flash,
with a gold panel adding some extra warmth to the subject.

2. A
vibrationless release device. No matter how rigid the tripod,
triggering the camera can induce vibration which will defeat all of your
precautions. Consequently, a cable release should be considered essential--to
trip the shutter without jarring the camera. In the past, a standard mechanical
cable fit virtually every SLR, threading into the center of the shutter
release button. However, most of today’s cameras require an electronic
cable switch or an infrared wireless remote controller; check your Owners
Manual for the correct model. Use one of these with mirror lockup--if
your SLR is so equipped--for vibrationless photography especially with
long exposures or when using telephoto lenses.
3. A great tripod accessory.
Although the tripod is acknowledged as essential for serious
photography, it’s not exactly renowned for speed of operation. When
the light is rapidly changing, what is more exasperating than missing
the decisive moment while fumbling to switch to another camera or lens?
Screwing equipment on and off is not only tedious, but when you’re
done, the lens is probably pointing in the wrong direction.
Fortunately, the entire process
can be facilitated with a quick release mechanism. This is a truly efficient
and practical alternative to the otherwise time-consuming chore of changing
cameras or lenses. While you’ll find numerous types and configurations
on the market, the basic concept is essentially quite similar. All start
with accessory plates which attach to the tripod socket of your cameras,
or the foot of the mounting collar of some heavy telephoto lenses. The
plate simply plugs into a bracket built into some tripod heads or sold
as an accessory. Changing equipment on a tripod now takes only seconds,
making the quick release devices invaluable in terms of speed and convenience.

Few flash units are adequately powerful for distant subjects,
making a Fresnel flash accessory useful for greater effective
“reach.” These devices also save on battery
power by reducing the amount of flash output required. (Canon
EF 500mm f/4.5L USM; 540EZ flash; Flash X-tender; Elite
Chrome 100.) |

4. Alternatives to
the tripod. The most effective blind for certain wildlife and
birds is your automobile, especially on safari, in national parks and
some refuges. Some photographers will rest a mini tripod or a beanbag
on the window sill of their vehicles. This tactic--or a lightweight window
mount from a tripod manufacturer--is often useful for shake-free exposures
with lightweight telephotos like the 400mm f/5.6 models.
But for longer exposures or
when using super telephoto lenses, a larger window mount will better exploit
the stability of your vehicle. For heavy pro telephotos (like the 600mm
f/4) check out the pro models like the Kirk Enterprises Window Mount constructed
of black anodized aluminium. Its lip grabs either the glass or the window
groove; the base which hugs the interior of the door provides additional
support. Add a sturdy ball-and-socket head which will allow the lens to
be pointed in any direction. For long lenses in difficult conditions,
such as shooting from a helicopter, try Ken-Lab’s “invisible
tripod” the Kenyon Gyro Stabilizer.

If you find the light from electronic flash overly “cool”
add an 81A warming filter to the flash head. Acetate filters
can be cut to size and attached with some tape. (Sigma 180mm
f/5.6 APO macro lens; fill flash with warming filter; Sensia
II 100 at EI 200.) |

5. Stabilizing devices.
Ever wonder how an archer with a crossbow can hit the bull’s eye
every time? He’s no more steady than you or I shooting with a 400mm
f/5.6 telephoto, but he has one advantage: a gunstock. With a design proven
successful through generations, combined with the perfect stance for shooting,
the stock assures precise accuracy, with minimal shake. You’ll find
various “shoulder mounts” including those from the Kirk Enterprises
catalog and others in our mail-order ads. Shapes, sizes, and construction
vary, so your choice will depend primarily on personal preference.
6. A supplement to
sunshine. Although some nature photographers will use flash only
as a last resort, an electronic flash unit is high on my list of favorite
accessories. Ambient light during much of an even splendid day can be
harsh and overly contrasty, with hard shadows cast over the subject. Then
there are the dark, overcast days and the deep woods with heavy foliage
blocking the sun. In such circumstances, a fine-grained slow (ISO 50 to
100) film is impractical without flash, unless you’re using a tripod
and your subject remains perfectly still. By relying on flash, you can
expand the “window of opportunity” from perhaps four hours
per day to many more.
Past experience with full flash
outdoors has led many photographers to believe that the effects are “artificial.”
They find that the lighting appears harsh, the shadows hard, and backgrounds
often unnaturally dark. Thankfully, the current high tech cameras--with
a dedicated multimode TTL flash gun--can help to achieve beautiful pictures
without tedious calculations. This is accomplished primarily by an “intelligent”
metering system that automatically reduces flash output by about 1.5EV
in bright conditions. Some high-end flash units and cameras even allow
you to further reduce flash intensity for a particularly natural effect.
Sunlight remains the primary
illumination with the extra burst of light providing fill-in lighting
only. The artificial flash look becomes a thing of the past. The extra
illumination can “fill-in” shadows or even out the lighting
for a more pleasing, less contrasty effect. Use it to brighten the center
of interest in backlighting, help to fully saturate colors, and to add
a catchlight to the eyes of birds and animals. When using 300mm or longer
lenses, a Fresnel screen accessory can be invaluable for increasing the
effective “reach” of flash. Several companies market such
devices, with the best known made by Visual Echoes (the Flash X-Tender.)

A car, van, or pickup often makes for a suitable blind in
parks and other “controlled conditions.” While
a beanbag draped over the partly raised window will afford
a measure of stability, a window mount accessory is more
effective with long telephoto lenses. (Canon EF 500mm f/4.5
lens; Kirk Window Mount; Fujichrome Sensia II 100.)

7. Remote Flash Accessory.
While on-camera fill flash can work nicely for subjects which are 10+’
from the lens, those which are much closer can benefit from remote flash
placement. In macro nature photography for example, the light from a hot
shoe-mounted flash will illuminate an area beyond the subject even if
the reflector can be tipped downward. Removing the flash unit from the
body can solve this problem.
In order to maintain full TTL
flash control, most SLR cameras now accept a TTL extension cable to extend
their dedicated features from the hot shoe to a remote flash unit. A few
camera/flash combinations provide Wireless TTL Remote Flash control and
Ikelite makes an accessory TTL Slave Sensor that achieves the same effect
with Canon or Nikon flash units. You can now hold one or more light sources
exactly where desired, and let the system handle exposure calculations
for you.
8. A third hand.
Some photographers hold an off-camera flash unit in their hands--above
and to the side of the subject--but this can be somewhat awkward. Off-camera
flash is more convenient when the unit is mounted on a bracket like those
used by news and wedding photographers. For wildlife photography, look
for a bracket which gets the flash as far from the lens axis as possible
because redeye in animals is prevalent with on-camera flash, even outdoors.
There are dozens of brackets
on the market from camera and flash manufacturers as well as independents:
Adorama, The Tiffen Company, Kirk Enterprises, and Hasselblad. (For extreme
close-up work, look for a model that is specifically advertised for this
application.) All are adjustable so you can control the direction of lighting
as well as the shadows; try placing one or two flash units in a slightly
different position for each frame of a series.

Although a tripod may be required when shooting at long
shutter speeds, the use of fast lenses or films can preclude
the necessity for this unwieldy device. A gunstock or shoulder
mount often makes for a more convenient alternative, with
telephotos up to 400mm. (Sigma 400mm f/5.6 APO HSM lens;
fill flash; Kirk Enterprises Shoulder Mount; Velvia at EI
80.) |

9. Contrast control
accessories. In spite of the advantages of fill flash, some photographers
prefer to rely on ambient light only. Thankfully, the accessory manufacturers
offer a broad variety of devices which make this approach feasible. Their
most valuable are the reflector panels, used for bouncing extra light
into essential subject areas, such as the pistil and stamen of a deep
blossom.
Homemade accessories can be
used, but I prefer the more durable alternatives like the gold/silver
and silver/white reflectors you see listed in several of our mail-order
ads. Available in various sizes and color combinations for creating pleasing
effects, these fold down to a third of their working size for maximum
portability. A 32” silver/gold reflector is my most frequently used
accessory as it offers a variety of benefits: especially fill-in for contrast
control, plus modification of the color and quality of light.
For nature close-up photography
in harsh, contrasty light, consider a diffusion screen: a translucent
cloth panel that helps to provide softer, more pleasing light. (These
are offered by many of the manufacturers of reflector panels.) Simply
hold it between the sun and your subject to provide diffusion. If desired,
use a reflector as well, to bounce some extra light onto an essential
subject area. Note: When using any of these contrast control accessories,
take the light meter reading only after the panel is in place; this will
avoid overexposure (with reflectors) or underexposure (with diffusion
screens).
10. An alternative
to macro lenses. One of the best accessories for extreme close-up
nature photography--with the highly popular tele-zoom lenses--is the “supplementary
close-up lens.” Resembling a filter with magnifying glass, this
accessory can substantially reduce the minimum focusing distance of a
lens (by shortening the effective focal length). Available in various
diopter strengths, these have several advantages over extension tubes,
especially with zoom lenses: they are smaller; there’s no loss of
light (for ease of focusing and for faster shutter speeds); magnification
can be increased by simply shifting to a longer focal length; and focus
does not shift as you zoom the lens.
Granted, these accessories
are not intended for magnification beyond 1x (or “life-size”)
and when used with a zoom lens they do not match a true macro lens in
terms of optical quality. Still, they are more convenient than extension
tubes and less expensive than macro lenses. Start with a lens of known
high quality, use professional techniques to avoid camera or subject movement
and stop down to f/11 to f/16. And be sure to look for the “double
element” or “achromatic” supplementary (or “auxiliary”)
close-up lens kits because these are effectively corrected for optical
aberrations.
Conclusion.
If any of the accessories surveyed seem to hold potential for your own
nature photography, shop around. Check our mail-order ads, request a catalog,
or check the pertinent web sites. There are numerous models available
from a broad variety of manufacturers, with one just right for your own
preferences. I have mentioned only a few as examples, but there is a vast
range of accessories out there--all designed to make photography successful
and more convenient as well.
