Over the top
Is it ever OK to
overexpose some
parts of an image?
Roger Winters
A
On most occasions, you are
looking to shoot your image so
that its exposure fits within the
camera’s dynamic range – but
this is sometimes impossible. If you are
taking a landscape shot that includes the
sun in the frame, for example, it’s inevitable
that some highlights will be blown out.
There are also times when you might
want to deliberately blow the highlights
out for creative effect. A high-key image,
where you want to minimise shadows
and have strong highlights, will also often
involve overexposing parts of the scene.
Ultimately, you are always looking for
the most impact from your images – so if
this requires deliberate overexposure (or
underexpose for that matter), then do it.
Always avoiding it will mean that sometimes
you miss getting the best shot. You have to
make a judgment at the time of shooting
and adjust your exposure accordingly.
When I took this image of a young ballet
dancer looking at his phone, I knew that
the light flooding in from outside would
completely blow out if I retained detail in his
body and the darker interior. The contrast
between his shape and those blown
highlights make the image; if I had retained
the highlight details from the exterior,
the photo just wouldn’t have worked.
Photography is all about working the
given light to your best advantage.
Over- or underexposing parts of the scene
to do this are just weapons you have at your
disposal to give your photos atmosphere.
Into the action
Q
I love photographing
motorsport, but I
can’t get a panned
action shot where the car
is sharp enough and the
background is blurred.
What shutter speed
do I need to get it right?

Panning is not a particularly
easy technique, Keith, and
requires a lot of practice to get
consistent results. The trouble
is, I can’t tell you the perfect shutter speed
to use for the effect you want to achieve,
because it depends on how fast the
subject is moving through the frame.
The advantage of panning your camera
with motorsport is that you can get a lot of
goes at it, since the cars are usually going
round and round a track. You can simply
stay in one place and keep trying. The
slower the shutter speed you use,
the harder it is to get the subject
sharp and the rest of the image blurred.
The most important thing is that your
panning motion is smooth, so lock onto
your subject as it comes into view, fire the
shutter as it is directly in front of you and
continue to follow its trajectory as the
exposure is made. If you wobble or shake
the camera during the time the shutter
is open, this will affect sharpness in the
subject. I’ll use shutter speeds between
1/15 sec and 1/250 sec to try and get
that combination of sharp subject and
blurred foreground and background.
The photograph of the racing car was
taken at 1/125 sec. The wheels show
movement, as do the grasses in the
foreground and the crash barrier and
trees in the background, but the car itself
is sharp. Incidentally, even if I am trying to
freeze a car speeding past me with a high
shutter speed of 1/1,000 sec or more,
I’ll still use this panning technique.
Q
LEFT: Sometimes, overexposing a shot to
leave out some the background detail is
exactly what the image needs.
Panning with your camera to freeze the movement of a car or athlete takes a degree of practice,
but it shouldn’t be long until you can capture shots like this.
