I’m always amazed when non-photographer
friends and neighbors show me their vacation pictures. Endless, bland,
front-lit building facades, along with seemingly interminable shots
of the kids and relatives squinting into the sun. A hundred years ago
this was recommended practice, as the family box camera, with its slow
lens and slow film, needed all the help it could get (in the form of
blasty front lighting) in order to deliver a successful handheld snapshot.
At the consumer level, at least, the esthetics of interesting lighting
had to take a back seat to the available equipment and materials of
the day.

Front lighting
would have reduced this architectural detail shot to
an uninspiring, two-dimensional flop. Strong sidelighting
accents the curves and planes, adding depth and interest.

Today, however, with contemporary
cameras offering fast optics, various programmed metering schemes and
auto fill flash, coupled with fast, sharp films, there’s simply little
excuse, other than lack of awareness, for dull pictures due to flat lighting.
There are, of course, unavoidable
circumstances (e.g., guided tours) over which you have no control, such
as tourist attractions encountered at an unflattering time of day, when
you have no time or viewpoint options. Another seemingly "total loss"
situation in terms of interesting lighting is the occasional cloudy or
foggy day. But, as you will see, while these circumstances present unique
challenges of their own, they often have their own set of creative lighting
solutions. The key is awareness.
Flat Light, Flat Picture
So let’s analyze the flat, bright-sun, front-lit photograph. Why is it
unexciting? What does it lack? If you’ve ever studied the great photographs
of the great photographers and the lighting that contributed to that greatness,
you will realize that three elements are almost always necessary: highlights,
mid tones, and shadows. It is this tonal range, or contrast, that provides
form, texture, and depth to the mechanically two-dimensional slide or
print. Even high-key and low-key photos, if competently exposed and printed,
will exhibit a white and a black in addition to the mid tones, even if
represented by only a tiny area of the image, such as (in the case of
a portrait) a highlight in the eye or a dark piece of jewelry. Whether
you are consciously aware of it or not, your eye will pick up that small
area and recognize it as the required balancing element.

any time when you spot perfect texture-enhancing sidelight
such as this; a couple of minutes later, this ornate

The Shadow Knows
The element missing from the front-lit scene, then, is shadows. There
may be one or more black objects in the scene, which can help in terms
of subject contrast (as opposed to lighting contrast), but this isn’t
the same as having shadows present. Shadows, created by a progressive
absence of light, define form. A front-lit black object has no more form
than a front-lit object of any other color.
You therefore need to be as
aware of shadows as you are of light when assessing the photographic possibilities
of a scene; after all, light and shadow are equal partners in the world
of photography. A major step upward on this learning curve is to shed
your lighting awareness "blinders." This means not becoming so mesmerized
by intriguing new vistas, whether landscape or cityscape, that you are
oblivious to other, alternatively illuminated, related subjects that exist
all around you in every direction. As you look around 360 degrees, unless you’re
standing in a pancake-flat landscape at high noon, the lighting direction
changes. This provides the opportunity of capturing a variety of kindred
photos to achieve a more in-depth coverage of a locale or subject.

Not only should you strive
to seek varied subject/lighting candidates all about you, you should also
try to recognize compositions requiring a variety of lens focal lengths.
By telling your photographic story in long, medium, and close-up croppings,
combined with differing lighting directions, you will maintain your viewers’
interest in the manner favored by major travel-oriented publications.
In every instance, though, each photo of the series needs to stand on
its own as a successful image; merely turning 90 degrees between each of four
wide angle shots won’t do it--you have to always be seeing a location,
not just covering it.
Subjects illuminated by extreme
sidelighting require fast action on your part. Don’t waste time looking
for something "better." By the time you decide there isn’t anything better,
the sun may well have moved on, leaving the subject either entirely in
shadow, or in increasingly more open frontal lighting, depending on the
sun’s direction of travel in relation to your subject. Zoom lenses are
a plus here, as they avoid time wasted looking for and changing lenses.
Exposure Considerations
In the same vein, you need to be familiar with proper exposure technique
under side and backlighting conditions. In the earlier instance, time
spent scratching your head in uncertainty, or wasted taking umpteen spot
readings, will, often as not, result in a missed shot. This is not the
time to have to be hunting through a 90-page camera instruction book.
Modern SLRs with segmented ("matrix") metering schemes generally deal
pretty well with sidelighting. A little experience with a particular camera
will demonstrate whether the meter pattern is habitually right-on, a bit
over, or a bit under. If consistently over or under (seldom more than
1/2 f/stop), simply enter the required correction on the camera’s exposure
compensation dial. In any event, a narrow (1/2 f/stop for slides, 1 f/stop
for negative films) bracketed frame or two is good insurance.

Backlighting is a bit more
tricky. The possible variables are greater and can have a greater effect
on the final photograph. While experience (and some note-taking at the
novice stage) is the best teacher, here’s the basic decision you have
to make and then execute technically with your camera: how light or dark
do you want the shadow side (the side you’re shooting into) of your subject
to be in relation to the (usually) much brighter surrounding background
area? This gets even more ticklish if the source of the backlighting (e.g.,
the sun) is actually in the image frame/metering field. Fortunately, with
most backlit situations, the light source is either out of the image area,
or obscured by the subject.
Relative close-ups can be handled
nicely via built-in, TTL fill flash. For longer shots, it will depend
on how important the bright surround area is. If it is of little consequence,
meter just the shadow area; my "insurance" brackets in this case would
be 1/2 and 1 f/stop under (with slide film) the metered first shot. If
the bright area needs to remain reasonably detailed, then take an averaging
reading of a 50/50 bright/shadow mix; my insurance brackets here would
be 1/2 and 1 f/stop over the initial metered frame. In practice, this
is much simpler and quicker than this narrative would indicate. With a
little experience, your response will become nearly automatic. Besides,
you generally have considerably more time to deal with backlit situations.
If you find yourself with no
meter, a dead meter, or simply no time to use one, the outdoor rule of
thumb for side and backlighting is to open up one stop for sidelighting
(over the correct exposure for a front-lit scene), and two stops for backlighting.
The "sunny-16" rule (f/16 with your film’s ISO rating as the shutter speed,
under bright sun conditions) will get you close to a front-lit exposure
combo. Time permitting, bracket as experience dictates.
To Photograph Or Not…
Inevitably, you will be confronted with blandly front-lit scenes that
present only two choices: take the picture or forget it. Regardless, take
the picture anyway. You may plan on returning, but plans change, and any
picture is better than no picture, especially on a once-in-a-lifetime
vacation. Even so, there are often ways to improve the shot. Look for
nearby darker, shaded objects to frame the bleakly-lit scene. These can
be trees, shrubbery, lampposts, cars, window frames and other elements
of buildings, even fellow tourists (from the back, thrown out of focus
via a large aperture or longer lens). Executed with a bit of flair and
imagination, this device can add depth and go quite a ways toward salvaging
an otherwise marginal picture.
This treatment works well on
cloudy or foggy days, too. While overcast lighting is flat, all but the
most leaden conditions still offer subtle modeling of shapes. Including
the shadowed back side of foreground portico columns, for instance, adds
a touch of the third dimension to an otherwise monochromatically lit scene
beyond.
So next time you’re traveling,
camera in hand, I hope you’ll look at new places with an eye toward depicting
them in the most interesting light. By maintaining a constant vigilance
to the lighting possibilities all around you and in every direction, you
will find that your ability to construct an entertaining visual essay
of any photo/travel outing will grow by leaps and bounds. Indeed, when
you experience the difference expressive lighting can make, your first
priority as you preview a scene through your viewfinder will be--"anything
but front light!"
Quick Guide To Travel Lighting
Awareness
- Always be alert to more
interesting alternatives to flat front lighting.
- Constantly check in all
directions for fleeting side and backlighting opportunities.
- Be aware of the difference
between subject contrast and lighting contrast.
- When a front-lit main subject
is unavoidable, look for nearby darker objects to frame the scene.
- Use smaller side or backlit
areas within or adjacent to an overall front-lit scene as detail shots.
- Work quickly with extremely
sidelit subjects, as the effect will fade momentarily.
- Practice your exposure
technique for side and backlighting; when in doubt, bracket.
