Buying studio flash
LIGHTING
Selecting the flash heads
Excellence in photography is as much
about light control, as about composition,
subject matter and so forth, and
many photographers will invest in a
studio flash system when they wish to
achieve this degree of control – for
portraiture, still life and many other
purposes.
As with most things, the more you
spend, the more power, flexibility,
sophistication and, to some degree,
build quality, you will get.
Flash heads aimed at the amateur
will typically have a power output of
125 or 250 joules, and will have a
switchable full/half power output, and
sometimes a fixed modelling light
output. These will be fine for small
studio use, and will give required
working apertures of f8/f11 at typical
distances.
Moving up the scale will get power
outputs of 500 joules or more, and
continuously adjustable power output
over a 5 or 6 stop range, fan cooling,
remote control, and the power to light
groups of people at 4–5m distances at
small apertures even when bounced
from an umbrella.
You can do a lot with one flash
head, an umbrella, and a reflector or
two, so getting into studio flash can
cost around the same as a new zoom.
Joules and guide numbers
A joule is an expression of electrical
power, and is sometimes shown as
w/sec (watt second). Guide numbers
with studio flash are a less reliable
guide to power, as the choice of reflector
will change the figure. Manufacturers,
of course, will tend to choose
the reflector which gives the highest
figure, so accurate comparison
between makes is not always possible.
Choosing accessories
Some subjects will benefit from direct
flash, but the big benefit of using a
studio flash head is the ability to add
an umbrella, or a softbox, or restrict
the spread of light with a snoot or
barndoor. The kits we show on these
pages all include several light modifiers
which will enable sophisticated
lighting effects to be achieved straight
out of the box!

Interfit
Colorflash i
Top-value new series of studio flash
heads featuring good power and
continuously variable power output
from full to 1/8th power (4 stops) –
now with upgraded tube. The 60w
modelling lamp also adjusts in line with
the selected power output, and can be
turned off if required.
Built-in infra-red sensitive slave allows use of infra-red
flash triggers, as well as triggering by the supplied sync cord.
Side-mounted controls are easy to get at, even if the head is
tilted down. Each head is supplied with mains lead, sync lead,
modelling lamp and removeable reflector.
