Using BIG LIGHT! SourcesUnderstanding the
Nature of Big,Soft Light Sources
by Stephen Dantzig, Psy. D.
Fashion photography is comprised of many subcategories.
Light is used in as many different ways to capture the image. A
beauty photograph will be lit in a vastly different manner than
a high fashion shot. Similarly, a commercial
fashion image is handled differently than high fashion. It is often
the quality of light that highlights the different approaches used
in the many facets of fashion photography.
Quality of light refers to how soft or harsh the light appears on
your subject. A soft light will show a gradual transition from highlight
to shadow and will cast lighter shadows. In contrast, a harsh light
will have quick transition from highlight to shadow and cast deep
dark shadows. The quality of light is a direct consequence of the
size of the light source relative to your subject and the distance
between the two. At a given distance, a small light source will
have a dramatically different effect on your subject than a larger
source. For example, a flash headfitted with a seven-inch parabolic
reflector set five feet from the model will have a relatively harsh
quality of light compared to the same flash head used at the same
distance fitted with a 30" x 40" softbox. However, if
the softbox were moved farther away from the subject, there would
be a point when the quality of light would become as harsh as the
source fitted with the seven-inch parabolic. Understanding this
basic law of physics can help determine what light sources are used
and how they will impact the final image.
The studio images depicted here were created with three Dynalite
Uni400 monostrobes. One monostrobe was placed in a Photoflex Large
Softbox. The other two strobes were placed in a Photoflex Medium
and Small Stripdome, respectively. Modified and direct sunlight
was used for the location photographs.
Exposures
The studio exposures were set as follows: the camera was set at
f/11 (the shutter speed, which really does not matter in the studio,
was set at 11ž4125); the main light was set at f/11 and 3 to 4 tenths;
the hair light from the medium Stripdome was set at f/11 and 41ž410;
the hair light from the small Stripdome was set for f/11 and 11ž410.
The film, Kodak Ektachrome E100VS, was processed normally. In other
words, I overexposed the film by about 31ž410 of a stop to add some
snap to the final image. The hair lights were set at different values
because of the relative size of the light sources. The smaller light
source has more contrast and might have blown out her hair had it
been set to the same value as the medium Stripdome. The main light
was metered by pointing the dome of the handheld incident meter
down the lens of the camera. The hair lights were metered by pointing
the dome of the Minolta Flashmeter V toward the lights. (Note: I
will set the values of the hair lights as high as f/11 and 71ž410
to f/16 if I am shooting a beauty photograph against a white backdrop.)
Beauty Headshot
The client for a beauty photograph is often a cosmetics manufacturer
or a firm promoting hair products. The shot is designed to advertise
how the clients products transform a young lady into a beauty
queen. The manner in which the set is lit is critical to achieving
that objective. Contrary to a portrait, the face is usually lit
from the front. The quality of light used is soft and even. The
makeup helps provide the shadows and contours of her face. The hair
is lit so it shines. The task is to show how this particular brand
of shampoo or that conditioner adds bounce and life to the models
hair. Understanding what impact the backdrop will have and proper
metering are also extremely important factors in the success of
a beauty photograph. My model, Georgia, was seated in front of a
table with a silver California Sunbounce reflector positioned at
an inclined angle on the table. The large softbox was fitted with
a Circlemask to create a natural round catch light in Georgias
eyes. The light source was placed as close as possible to her to
soften the quality of light illuminating her. It was positioned
high, but directly in from of Georgia. The box was angled downward
so it would light the mask of her face while hitting the Sunbounce
to fill in the shadows under her nose and chin. The silver card
under her face adds the second set of catch lights and completes
the beauty look. The two Stripdomes light Georgias
hair. The medium Stripdome was placed on Georgias right and
positioned slightly behind her. The small Stripdome was placed in
a similar position on the opposite side. Both hair lights were flagged
with two homemade gobos.
Full-length Fashion Setup
The same lights were used for the fashion set-up. The positions
and values were changed. The softbox was moved about five or six
feet from Georgia and placed on her right side. The medium Stripdome
was moved to her left and positioned slightly in front of her. The
small Stripdome was moved to her right and was positioned slightly
behind her. The values of the lights were shifted so the softbox
provided a general ambient light level while the Stripdomes provided
the main effects. Again, the size and placement of the light sources
helped determine each lights output. The larger softbox was
set to about f/8. The medium Stipdome, which essentially acts as
the main light in this shot, was set at about f/8 and 4 or 5 tenths.
The small Stripdome adds a kick to Georgias right side and
outlines her face and was set at around f/8 and 2 or 3 tenths. The
final exposure, metered toward the camera lens ranged from f/11
and 2 tenths to f/11 and 5 tenths, depending on which lights were
illuminating the spot metered.
High fashion, or editorial fashion, is often described
as edgier than other forms of fashion photography. The
lighting is often harsher and the visual impact is quite different.
The same three light sources were used to create the full-length
image of Georgia. However, the impact of the smaller light sources
is more dramatic because of the interplay of each sources
size. The medium softbox was moved back several feet, but not far
enough to dramatically alter its quality of light. The Circlemask
was removed, increasing its size and further reducing the effect
of moving the light. Even though the exposures for the three lights
were fairly similar, the Stripdomes now appear more prominent because
of the harsher quality of light. The smaller sources add a lighting
edge to the image.
Commercial Lighting Setup
The main light for this image was a flash head fitted into a medium
Stripdome. The Stripdomes would normally be considered a harder
light source. However, when brought close to Georgia and with the
spill-off reflected back, it produces a beautiful light source for
this image. If you look closely, however, you will notice that the
specular highlights on her left cheek and forehead are a little
bright, belying the relatively small light source. The lights were
metered at about f/11 and 21ž410 and the Plus-X black-and-white
film was exposed at f/8.
This shot depicts an image that would generally be considered a
commercial shot. This photograph could be used in any number of
applications and also demonstrates the effect of bringing a relatively
small light source closer to your subject to create a soft quality
of light. The mainlight was the medium Stripdome! The same light
source that created the lighting for the high fashion
shot provides a beautiful main light for this character study of
Georgia. The light was brought in close, just out of camera view,
and was partially feathered across her face. A large silver card
was placed on Georgias right to add some fill and a smaller
silver card was placed on the floor in front of her. The small Stripdome
provides the hairlight.
Using Sun and Open Shade
Commercial fashion shots are often designed to show
the clothing in such a way that every detail shows. The lighting
is generally cleaner than a high- fashion image and
the final placement of the image may be in a catalog or point-of-purchase
display. The assignment may entail photographing a model wearing
the garment in a natural setting. The sun is a perfect example of
how the size of the light source interacts with the distance between
the light and subject to create the quality of that light source.
There is no bigger light than the sun. However, the extreme distance
from the earth to the sun turns that huge star into a pinpoint light
source. The two photos on page 14 were shot on a sunny beach in
the afternoon. However, they were not shot during the magic
hour, where the sun is low and beautiful. One image shows
the effect of modifying the sunlight, while the other uses its harshness
to enhance the image.
Finding or creating open shade is the way to photograph location
shoots all day long! The sun was still too high in the sky to photograph
Georgia without creating difficult shadows. Georgia is standing
under a 77" x 77" Litepanel fitted with a translucent
fabric. Another Litepanel fitted with a gold fabric provides the
feeling of the warmth of a setting sun. The translucent scrim is
positioned about two feet over her head, turning the pinpoint light
of the sun into a large and beautifully soft light source. The gold
reflector provides catch lights in the eyes. The light off the gold
is still pretty bright and you run the risk of your model squinting.
Be aware that the background will be somewhat overexposed because
you are metering for the light under the shade. The shot was metered
towards the camera. The meter reading was f/8 and 31ž410 at 11ž4125
of a second. The camera was set at f/8 and 11ž4125, overexposing
the transparency film by 11ž43 of a stop. Georgia pulls this shot
together. My assistant was positioned on the sailboat out in the
distance and held the boats position long enough to be in
the perfect spot for this shot!of course Im joking.
In the horizontal shot I made, Georgia was positioned by the shade
of the pier, but still in direct sunlight. By this time the sun
had begun to move down the beach. The angle of the sunlight
along with the pier providing some respite creates a hard-soft
light combination that was perfect for this shot! The mainlight
is the light reflected off the sand and diffused by the pier. The
direct sun provides a terrific rim light to accentuate Georgias
body. The camera was set at f/11 at 11ž4125 of a second for this
shot and was metered at about f/11 and 2 or 3 tenths at 11ž4125
of a second.
Understanding the physics involved with lighting and proper metering
are certainly critical components to any successful photo shoot.
However, the rapport established with the young lady in front of
the camera will make or break your shoot. Georgia was not only absolutely
beautiful; she was a pleasure to work with!
