The
Basics of Nature Photography
Text and images copyright Cindy Marple, all rights reserved
Are
you new to nature photography? Feeling a little unsure of how to get started
in your quest to make beautiful images? If you want to consistently make
good photos, there is a lot to learn. Fortunately, there are a tremendous
number of resources out there to help you, but these can also be overwhelming
to sort through. Here is an overview of the topics you will need to learn
about from a nature perspective, and some guidance on the different resources
available.
Let
me start with a very basic statement. There is a difference between making
a photo and taking a snapshot. Maybe it’s because most of us have
had access to a camera for taking family snapshots since we were young,
that it can take a while before that realization and transformation occurs
(and sometimes it never does!). Making good photos is a “whole brain”
experience. A technically perfect (left brain) image can still be unappealing
if the artistic part is overlooked. But to achieve your vision (right
brain) you need to know how to make the tools work. And it takes time
to thoughtfully put all of it together to make the photo. Simply pointing
and clicking will rarely get you there.
The
Left Brain Stuff
Equipment-
Cameras
In selecting a camera, first define what you want to do with it. Nature
is a broad genre and different subjects may require different equipment.
Some categories to consider are macro / close-ups, scenics, wildlife,
and birds. Fixed-lens (point and shoot) cameras can be used for the first
two but are generally not well suited for wildlife and birds, and will
have limitations for any subject that you may find frustrating as you
progress. A DSLR (digital single lens reflex) camera with interchangeable
lenses will give you versatility and the ability to grow and upgrade over
time. The instant feedback provided by digital as opposed to film will
vastly accelerate your learning curve.
Here are some features to consider when comparing DSLR cameras.
Sensor
size or “Crop factor” (field of view multiplier): DSLRs
have physically different sized sensors. Sensors smaller than one frame
of 35mm film have a multiplying effect on the focal length of a lens.
On a camera with a 1.6 field of view multiplier, a 100mm lens would be
equivalent to 160mm. For landscapes, where short focal lengths are used
frequently, less magnification is desired. For birds and wildlife, greater
magnification will extend the focal length of your lenses.
Frame
rate: This is how many frames per second the camera is capable of
exposing. This is useful for action but not important for still subjects.
The buffer size in a DSLR is how many images are stored in the temporary
memory before being written to the card. Generally this goes along with
frame rate; the faster you can shoot, the bigger the buffer you need.
Mirror
Lock Up: In an SLR camera, there is a mirror in front of the sensor
(or film) which reflects the scene into your viewfinder, and moves up
out of the way when the shutter is tripped. The mechanical vibration of
this movement can cause blurring of your image at slower shutter speeds.
A “mirror lock up” mode allows you to move the mirror out
of the way first, and then trip the shutter to eliminate this vibration.
This is a highly desirable feature for close up and scenic photography
but is one that many current cameras do not include.
Equipment-
Lenses
For an overview of what the difference is between lenses, two good resources
are Canon
Lens (click on the EF Lenses 101 box) and Photo.net.
Another tip to figure out what you need is to browse through the NatureScapes.Net
forum featuring your favorite photographic subject and check the lenses
and focal lengths people are using.
Equipment-
Tripods
A sturdy tripod is a necessity for the serious nature photographer. For
macro and scenic work, you need the stability for fine-tuning compositions,
as well as for long exposure times. For wildlife and birds, you need the
support for the weight and size of the lens to achieve the sharpest images.
Look for a tripod that is capable of going low to the ground, i.e., that
has no (or short) center column and no supports between legs that limit
this ability. Ball heads are generally preferred for shorter lenses and
gimbal-type mounts, such as the Wimberley head, are generally preferred
for super-telephotos.
There are times for handholding, such as when shooting from a motorized
boat to avoid transferring the engine vibration to the camera, or for
flight shots of birds. For handholding, a general rule of thumb is to
keep shutter speed faster than 1/lens length. For example, with a 200mm
lens, shoot faster than 1/200 second. With vibration reduction (VR) /
image stabilization (IS) technology you can go a couple stops slower than
this. To achieve best sharpness, support the lens with your left hand
under the barrel, tuck in your elbows, hold your breath and squeeze the
shutter gently using the muscles in your finger and not those in your
arms or shoulders.
Equipment- Filters
The camera store sales person will try to sell you a Skylight filter for
protection of the lens front element. The filter itself has essentially
no positive affect on the image. A cheap (<$10) piece of glass placed
in front of a good quality lens can degrade image quality. But it can
also protect from blowing dust, salt spray, and an accidental drop. Best
to get a good quality filter if you choose to use one, but ask yourself
if you really want any glass at all in front of your good lens when you
are shooting. Most nature photographers go without.
Other
filter types used for nature photos are color correcting, graduated neutral
density, and polarizing. The first two can be replicated in photo editing
software and are therefore not as useful as they were in the film world.
There is also software that emulates polarizers, but many of us still
use the filter; it reduces glare, deepens the blue of the sky, and enhances
rainbows.
Equipment-
Flash
The need for flash, and type of flash, depends on your choice of subject.
It is not commonly used for scenic photography or many wildlife subjects.
Most bird photographers carry a flash along with a “Better Beamer”
Flash Extender to increase the reach of the flash. For macro work, there
are specialty flashes and flash brackets that are used to get light into
very small, close objects. The pop-up flashes found on some cameras are
not particularly useful for most nature photos. Learning to use flash
well is a study unto itself, more info can be found on Moose
Peterson's site and in the article
in this issue by Ralph Paonessa. Flash questions are frequently answered
in the NatureScapes.Net photography forum.
Exposure
– correct exposure
Achieving correct exposure is fundamental to making good photos. Most
how-to books will cover the facets of exposure in great detail. The camera’s
meter assumes the scene is middle-toned, not light or dark, and will give
correct exposure for mid-tone. But nature is full of subjects that are
not middle-tone, such as sunrises and sunsets, polar bears in snow, blackbirds,
or white flowers. You must learn to identify these situations and how
to compensate from what the meter indicates for settings. Compensation
is done differently depending on what you are metering: the subject itself,
a middle-tone object in the same light, or if you are using an incident
(handheld) light meter. Pay attention to this when reading about or hearing
about compensation; it will help you sort out seemingly conflicting instructions
given by different people.
An
incredibly useful tool on digital SLRs for validating your exposure is
the histogram display. See Greg
Downing’s article in the NatureScapes.Net archives for more
information.
Exposure
– latitude
The other exposure problem you will encounter in nature photography is
a scene that exceeds the exposure latitude of your film or sensor. If
the difference in exposure from the brightest to darkest area of the image
exceeds about 6 stops, a digital sensor will be unable to record detail
in the entire scene because of the camera’s limited dynamic range.
Either the bright or dark area will be rendered detail-less. If you can’t
work around the subject to reduce this difference, in general you should
expose for the brightest area and let the dark part go black. Artistically,
it is more acceptable to our eye to lose detail in darks than in whites.
This issue is commonplace in landscape photography at sunrise and sunset
where part of the scene is still in shadow and part is brightly illuminated
by the sun. With digital, you can make multiple frames of the scene, each
one with a slightly different exposure to capture detail in different
areas. You then merge the frames together in your photo editor. See Royce
Howland’s article on HDR. With film, the solution is to use
a graduated neutral density filter. This is a piece of glass that is clear
on one half and darkened on the other; by placing the dark area of the
filter over the bright area of the scene you reduce the difference in
exposure value to one which may be handled more evenly.
In
some situations you may be able to reduce the difference with flash. If
you have a subject in shade with a sunny background, you can use a balanced
flash. With the camera in manual mode, meter the bright background and
set the camera to underexpose it by 1 stop. Set your flash to no compensation.
The flash becomes the main light to illuminate the subject, and the bright
background is darkened by the underexposure, thus balancing out the difference
in tonality.
Exposure
– controls
Exposure is controlled in any camera by ISO, shutter speed, and f-stop.
Lower end point and shoot models may not give you access to these controls
but SLRs do. These control settings affect the appearance of your image,
ISO to a much lesser degree, as it is a rating of the sensitivity to light
of the sensor or film. You change the ISO depending on the amount of available
light, to give you the range in the other settings that you need. You
may wish to set the ISO to steadily increasing numbers to increase the
light effects, for example, as the sun goes down. The biggest impact with
digital is that you start to get noise (speckles) at higher ISOs (low
light). Usually you want to use the lowest ISO that will give you the
shutter speed and f-stop desired. Shutter speed is how long the shutter
is open, and varying this controls the amount of motion blur of a moving
subject. F-stop controls the depth of field, or how much of the image
front to back is in focus. These are critical in all nature photography;
you will want to make these choices consciously in your image. Make sure
you know how to operate these controls on your camera.


The
Right Brain Stuff
Composition
Composition is the purposeful arrangement of the elements of a photo.
Although it is highly subjective, there are some basic rules of composition
that should be learned. These are tried and true methods (some are centuries
old painting rules) that will give good results. Once you understand these
rules, intentionally breaking them can give dramatic results. This website
gives an excellent overview of the basic rules of composition: Fodors.com.
For
nature photos, here are some additional considerations for composition.
-
Focus
on the eyes. If your subject has eyes, the viewer will be drawn to
the eyes as a center of interest of the image. As such, the eyes should
be in crisp focus, even if other parts of the subject are not due
to depth of field or motion.
-
Give room for the subject to “move into.” If your subject
is moving, and you place it near the edge of the frame in the direction
it is moving, the viewer’s eyes are taken right out of the image.
Leave space in front of the subject, not as much behind it. An exception
here could be if there is a trail behind the subject that is interesting,
such as dust clouds or water splashes. Similarly, with a static subject,
leave space in the direction the subject is looking, rather than having
it looking out of the frame.
-
Pay attention to the background.
-
Avoid white spots. The eye is naturally drawn to the brightest
area of an image. If that is not your subject, the eye will be
drawn away from the subject to that bright spot. Look for white
or bright objects in the background and try to eliminate them
by changing your point of view.
-
Avoid horizons cutting through the subject. When there is an abrupt
color transition or horizon line, try to place the subject entirely
above or below that line or eliminate the line all together by
raising or lowering the camera.
-
Watch for unwanted objects in the background creating a merge
with the subject. An example might be a tree that appears to be
“growing” out of the subject’s head. Try moving
slightly, or waiting for the subject to move, to eliminate the
merge.
-
Don’t clip the edges of your subject. If you’re going
to crop in on the subject, crop in far enough so that it is intentional,
don’t just leave the tip of a leaf or wing out of the frame.
If your subject is standing in something where the feet are hidden,
include enough space at the bottom to include the “virtual feet.”
-
Shoot at your subject’s level. This is particularly true for
animals or birds, and will achieve a more intimate feeling than shooting
down or up at the subject. It may mean getting down on your belly
or up on a hillside. Of course the inverse of this can also be used!
Dramatic angles, subjects photographed at a different perspective
than normally viewed, can be extremely effective.

Light
Light is another element that has a profound effect on the outcome and
artistry of an image. The type of light and color of light are important
factors in your image.
Light
can come from a point source such as the sun or a flash. This type of
light has direction and casts shadows. The direction has a huge impact
on your photo. When the light comes over your shoulder and directly illuminates
the subject, it is called front lighting. This type of light renders the
most detail in your subject and is commonly used for birds and wildlife.
Light coming slightly from the side adds depth, dimension and texture
and can be very effective for landscapes or to create a mood in the image.
Backlighting is the trickiest to deal with in terms of exposure but creates
drama and mood and can give very artistic results. (Backlit example, left.)
Rim
lighting, that bright outline of an object that can enhance fur, spines
or other textures, is obtained with backlighting when the sun is at a
low angle. A starting point to expose backlit subjects is to underexpose
a middle tone object by 1 stop. Then bracket (shoot at different exposures
just above and below that) like crazy.
Diffused
light, such as that on an overcast day or in open shade, casts no (or
minimal) shadows and so has no apparent direction. This type of light
is ideal for a situation where you want detail, as nothing is obscured
in shadow. Close ups of flowers, leaves and other objects, as well as
waterfalls, forest and fall color scenes are a few examples where diffuse
light works well.
A
more subtle aspect of light is the quality or color of the light. Light
is constantly changing throughout the day, and can even change minute
to minute in conditions where storms are a factor. You can greatly enhance
your pictures by paying attention to the light and how it is (or isn’t)
changing.
The
time of day also matters. In midday, cloudless conditions, the light is
bright and harsh. There are few shadows. Pictures taken at this time of
day tend to look flat and lifeless. However, at the more northerly and
southerly latitudes particularly during winter, the sun may never get
high enough for this to be a problem.
Early
or late in the day, when the sun is lower in the sky, more of the blue
color is scattered by the Earth’s atmosphere and what comes through
is more orange / reddish, or “warmer.” Between this warmth
in the light and the dramatic shadows you get this time of day, photographers
refer to these times as “magic hours.” The further away from
the equator you are, the longer this special time lasts. Many landscape
and nature photographers organize their day so that they are taking pictures
early and late, and midday they nap, travel, or scout new locations. It
may be a little extra effort to get up and get out early, but it can be
well worth it. This has benefits if you like to photograph in popular
parks or tourist locations, as these times will be much less crowded than
midday!
There
are also some situations where the light is noticeably cool, or blue.
This happens in open shade, in overcast conditions, and at higher elevations,
for example. This cool cast can be an important mood setter for your image.
However it tends to be less desirable than warmer light for many nature
images. You can “correct” this blue cast out of an image several
ways. A warming filter (81A, B or C) can be employed when you take the
photo. On digital cameras, you can set the white balance for cloudy or
shade conditions. Or you can correct in photo editing software in several
different ways.
Resources
There are many resources available for learning about nature photography,
from the basics to advanced techniques.
Web
sites
Of course, you’ve already found the best web resource for nature
photography here at NatureScapes.Net! Check out articles
and the online
forums.
Books
-
John Shaw’s Nature Photography Field Guide. This is an outstanding
basic resource. It covers all of the subjects mentioned in this article
in detail.
-
Joe McDonald’s The New Complete Guide to Wildlife Photography.
Another basic resource with a focus on wildlife. This book includes
an excellent section on flash.
-
Arthur Morris’s The Art of Bird Photography. A must read for
those interested in bird photography.
-
Joe McDonald’s Digital Nature Photography- From Capture to Output.
A new book on cd, intended for use in the field, it covers the basics
with an emphasis on digital, including basic digital workflow.
-
Classes
General photography classes may be available in your area. Check with
camera stores, parks and recreation departments, and community colleges.
Sometimes even zoos or gardens or other organizations in your area that
provide adult leisure learning type of courses may include photography.
These should be modestly priced but will not likely be strictly nature
photography. There are also web-based classes available, here is one example:
Betterphoto.com.
Seminars
A seminar is a lecture, typically to a large audience. Many nature pros
put on seminars in major metropolitan areas from time to time. They are
often day-long programs that cover all the basics. There will be a lot
of information and examples but typically limited time for questions or
personal instruction.
Workshops
Workshops are typically multiple day sessions with a low student-to-teacher
ratio (less than 10 students per instructor, often far fewer). There will
be both classroom time and time in the field. With digital there should
also be ample opportunity for review and critique. This type of setting
is probably the best for rapidly advancing your knowledge and abilities.
Photo Tours
Don’t confuse a photo tour with a workshop. A photo tour is designed
to get you to a particular destination at the right time. Although the
leader should be very knowledgeable and helpful, this is not typically
intended to be an instructional event. The exception may be for some highly
specialized technique to be employed. If in doubt, ask questions before
you sign up. These are usually not cheap trips and you don’t want
to be disappointed.
Camera
Clubs
Most major metropolitan areas will host one or more camera clubs. Local
camera stores may be able to help you find out about them. A few may be
nature oriented but most will be more general. Clubs vary a great deal
in terms of what they offer and their meeting format and frequency. Most,
if not all, welcome beginners (new members are life blood!) Many will
have field trips; some will have workshops or other instructional events.
All will give you an opportunity to talk with other photographers in your
area.
