Digital difficulties
Too early!
Got it right this time!
When shooting action, panning gives the best results. Now many of you will have
cameras with an “Action” or “Sports” mode that you can select at the flick of a
switch. Despite what the camera manufacturer would have you believe,
professional action sports photographers don’t use it! It does not give you
“action” shots.
The reason for this is simply that the selection of the
“Action” mode puts the camera on to a fast shutter speed to “freeze” the action.
That gives you a very static shot of your moving subject - a shot which does not
imply movement or action at all. A shot of a dog running can end up looking as
if Rover was frozen to the spot with its legs in a strange position.
Contrary to that which you would imagine, the technique to
show speed and action is not a super fast 1/1000th of a second shutter speed or
even faster with some of today’s super SLR’s - but rather something around
1/15th to 1/30th. Now that really is surprising, isn’t it? However, for this to
work, the technique to handle this slow shutter speed is called “panning”.
The objective with panning is to be able to “stop” the moving
subject, but leave the background a blurred smear. This is carried out by moving
the camera in time with the moving subject, so that the subject is in the center
of the frame at all times, while the background “moves” behind the subject.
Moving the camera to keep the subject in the center means that the slow shutter
speed is “fast” enough to stop the subject’s action, but too “slow” to stop the
effect of the movement of the camera on the background.
This, by the way, is not an easy technique and will require
that thing called “practice”, especially for those with digital cameras. Begin
by picking on an easy subject, like motorcycles going past you down the road.
Start by selecting 1/30th of a second for the exposure and practice turning your
body as the subject moves past you. You have to synchronize your movement with
that of the moving subject, and when you press the shutter you must continue to
move at the same speed especially when the viewfinder goes black as the shutter
fires and you cannot see the subject for a brief instant - the most important
brief instant.
When you have become good at this technique at 1/30th of a
second, it is time to then try 1/15th of a second. At the slower shutter speed,
the background will become even more of a streaky blur, giving an even greater
impression of speed and action.
With SLR film cameras, where you could use the WYSIWYG
feature (What You See Is What You Get) and see directly in the viewfinder what
the final image would be, panning was difficult, but not impossible. With the
new digital age of ‘easier’ photography, it turns out that panning is actually
slightly harder. The reason is that the electronic image you see is not quite
“real time”, but there is a split second difference, and in that split second
you can lose a moving image.
Take a look at this week’s photos of a classic car doing
around 100 kilometers per hour. In the first shot, the shutter was tripped too
early, so we have lost the back half of the subject. In the second shot, the
photographer managed to get the car central as he moved the camera in time with
the car.
To sum up, to show action and movement, select a slow shutter
speed and stand side on to the action. Turn your body as the subject goes past,
keeping the subject in the center of the viewfinder. When the subject is
directly opposite your position pop the shutter, while still continuing to turn
your body in time with the subject. With luck, you’ve got it!
