Most of all, I would like to express my awe and wonder for my lifelong muse, Belinda. She is as constant as the North

human being. I also want to acknowledge you, the gentle reader. Without you, these books would have no purpose.

Iits essence, it’s all about the
interplay of visual content and light.
Most photographers use the light

scene or a person or an object that
they want to photograph, but there
is a separate breed of photographers
who crave control over the images
they create. We’re not above using
available light if it works, but we’re
equally ready to jump in and give
nature a hand with a toolbox full of
lighting devices, chosen to add a lit-
tle extra texture or sparkle to a pho-
tograph. If you are like me, you just
feel more comfortable knowing
that, with a well-placed light, you
can reduce a lighting ratio for better
reproduction, reduce the texture of

ate a lighting design that will give

most practical use. It also covers the “supporting cast”
of equipment such as light stands, battery/inverter
packs, light meters, backgrounds, and more.
My goal is to help you make intelligent decisions
when choosing and using the most appropriate gear
for your projects, your style, and your budget. You
might never need the incredible precision of a Swiss-
made Broncolor studio flash, but it’s good to know
why they exist, what they are used for, and perhaps ul-
timately why you don’t need one.
No matter what category of light you choose, you’ll
find that selecting a high-quality model from a rep-
utable manufacturer may be a bit more expensive up
front but will probably give you more reliable service
in the long run. You’ll also find that, in the case of stu-
dio lighting, the quality and availability of accessories
is at least as important as the specifications of the core
products.
In the past, I would have said that lights are “cam-
era neutral,” meaning that the lights work the same
way no matter which format camera you use. That was
1
true in the film days, but now the realities have
changed. Digital cameras have shifted the playing field
by delivering higher and higher ISOs with better and
better quality. That means you’ll need less power to
deliver the same quality. Ubiquitous Photoshop post-
2
production has reduced the need for studio lights to be
designed to deliver exactly the same amount and color
of light with each pop. In the days of film, the tighter
voltage regulation and the higher quality of the elec-
tronic pathway meant less variability in exposure. And
in color slide film what you shot was what you got.

studio electronic flash, worldwide) has recently deliv-

own mixture, but one thing was true in every case: the
mixture was extremely flammable, could be explosive,
and the brighter it burned the more smoke it gave off.
Here’s the way photographers (brave souls) used
flash powder: First they would have to test the mix-
ture, the distance from the subject to the flash powder,
and the particular batch of hand-coated film they in-
tended to use. Once they got a good idea of the right
exposure based on their tests, they could move on to
real subjects. All the cameras of the era were basically
view cameras, so the photographer would evaluate the
scene through the lens onto the dark, ground glass of
the camera, focusing and composing on a very dim
image. He would then close the shutter, stop down
the aperture of the camera to his “pre-tested”
f-stop, and put in a film plate. He would then pull the
dark slide so that the film was open to the lens.
At this point, the photographer (or his unlucky as-
