All of us
at some time have tried some form of aerial photography.
Whether it be from the window of a 747, the top
of a tower or from the chairlift at the show. Aerial photography
reinvents our outlook on the world, radically adjusting
the all-important viewpoint in our photography.
If you know
youre planning a flight, a few simple rules will
help you maximise the situation and come back with
photos to make your
friends envious...
Choose
your aircraft
Helicopters
are naturally best for their ability to fly slowly and
basically wherever you want. The down-side is
their expense which
can be minimised by sharing the trip or even doing a deal
with the company if theyre going
somewhere anyway.
Fixed wing
aircraft are a cheaper alternative to helicopters but
fly higher and faster keeping you on your toes.
Make sure its
of the high-wing variety, preferably without the obstruction
of struts or protruding undercarriage.
Hot air balloons
provide a more sedate and relaxed atmosphere provided
you dont mind getting up at dawn! Of
course its not
so easy to double back and reshoot but the added lure
of a champagne breakfast should at least
make the trip enjoyable. Its not particularly
cheap (especially as youre sharing with others),
so remember to have fun as well.
Domestic
and International aircraft shouldnt be dismissed
as some great shots can be done through the scratched
(double) perspex youre
issued with when you request a window seat. Keep your
fingers crossed for a seat with
no wing to obstruct your view and fit your camera
with a rubber lens hood to minimise reflections.
Choose
your camera
A 35mm SLR
is the easiest and most reliable tool for aerial photography.
Make sure its a camera that youre
familiar with and
isnt prone to jam or misload. I use a Nikon F4 in
one of the few situations where its advanced
functions really come in handy. The two most useful
features to look for are auto or program exposure and
a motor-drive. Everything happens very quickly,
so time lost winding or bracketing is money down the drain
and a break
in your already strained concentration.
A medium
format camera is a challenging and satisfying addition
to your kit. Forget waist level finders; get
yourself a prism (preferably
auto-exposure) for viewing, its virtually impossible
otherwise. I use a Bronica SQAi
with an AE prism and speed grip which is very usable
though I really should get a strap so I dont lose
it!
Finally,
a panoramic camera is definitely worth a look but keep
it tilted down or youll have some lovely rotor
blades framing your
shots (assuming youre in a helicopter). I use a
Widelux F8 which is small and easy to use,
but slow to load with film if youre in a hurry,
so be prepared and aim to shoot one roll or get a friend
to reload for you. To get
around the lack of exposure meter, either use the 35mm
camera reading or bright sunlight rule
(ie. 1/125 @ f8 on Velvia) and work around that.
Dont put all your eggs in this basket, just take
the camera along
for a few extras while your SLR is rewinding.
Choose
your film
As most of
my work is for publication, I shoot transparency film,
primarily FujiChrome Velvia and Provia 100.
While Velvia is a
little slow for aerial work, a one stop push will increase
its speed to that of Provia and increasethe overall contrast
a little too - often a good idea for hazy conditions.
Basically choose a film of at least 100 iso but not too fast
unless youre working at dusk or night. Its
probably best to clip-test a roll or two to monitor the
film/camera combination and avert potential disaster
but once the film speed situation is sorted out, exposure
is relatively
consistent, even easier than on land!
Colour negative
film offers greater exposure latitude but is naturally
at the mercy of the mini-lab in terms of print
density and colour.
Most conventional 100 or 200 films will work fine, with
additional contrast changes possible
with varying paper types.
B&W film
can offer an interesting alternative, depending on what
youre trying to achieve. Ive seen some great
shots taken on B&W
Infrared (youll definitely need to load this beforehand).
With Kodak High-Speed Infrared
1/250 @ f8 on a sunny day will work well.
The Ilford and Konica equivalents (one and two stops slower)
can also
be used with appropriately high shutter speeds.
Plan
your moves
Discuss with
the pilot where you want to go before the flight so as
it can be cleared with the traffic control
beforehand. On my
last flight, one location was directly under the airport
flight path and required special clearance
and some wasted time in a holding pattern while a
737 landed.
Pre-load
your cameras (including a spare 35mm in case your main
camera takes a holiday). This will save
valuable time and
allow you to start taking pictures from the moment you
leave the ground.
Un-cap your
lenses. Again this will save time when changing lenses
and minimise stress. I use fixed lenses for
most of my work (20mm,
35mm, 50mm) although an 80-200mm zoom (preferably a fast
one) will give you some very
interesting shots of the world down there.
Stick to
one film speed if possible. Its easy to make exposure
mistakes on the ground and much easier in the air.
Set this on all your
cameras before you go and have all your film accessible
and the same emulsion so you dont
get mixed up.
If youre
shooting program (which Id recommend on a modern
SLR), set all your lenses to the appropriate
setting (minimum aperature
- f22 on most Nikon lenses) and lock it there if possible.
I generally shoot on Program High which selects high shutter speeds and closes
the lens down a stop or so when theres enough light.
Aperture
priority is quite usable too - set your lens to f4 or
f5.6 and youll be working around 1/500 or 1/250
which is ideal. You
dont need the depth of field - everything is at
infinity, especially on a wide angle lens. Avoid shooting wide open
unless necessary as you might lose some sharpness (especially
on the corners) or even overexpose
the shots if your camera only goes to 1/1000 sec.
In
the air
The main
thing to remember is KEEP CALM! If youre well prepared,
everything should be fine. If the camera
stuffs up, grab your
spare - dont waste precious time and opportunity
trying to fix it.
Remember
to keep your horizon level. Sometimes its easiest
to concentrate on keeping the horizon parallel to the
edge of the frame
and letting the rest of the image take care of itself.
This can be a tricky task but well worth the
effort. At the same time, avoid too much sky as it
may force the camera to underexpose as will bright highlights
on water,
expanses of sand or salt or the stereotypical hot
tin roof.
Finally -
dont drop anything. I heard a story the other day
about a famous Melbourne architectural photographer
who dropped a very
pricey Noblex panoramic camera out of a helicopter into
the murky Yarra. While this may
make you wince, so will a lens cap from a kilometre
up when it hits you in the head! So be careful and methodical
about where you position
your equipment and have the strap around your neck at
all times.
