Fundamentals
Creating a good exposure is the essence of any successful photograph. Even
the best creative ideas and the most dramatic of situations will fall flat if
careful attention is not given to how the tonalities of a particular scene are
recorded. And conversely, even rather mundane subjects can be transformed
into exciting photographs when creatively seen and recorded using well-
considered manipulation of exposure controls.
It's easy to think that with today’s sophisticated metering and exposure
systems and the ability to record images in the Raw format (where changes
can be made to exposure after the fact) that good exposure is “automatic” or
that the camera (and software) will do the work for you. But good exposure is
more than merely recording the tonalities within a given scene correctly; it’s
also largely a matter of personal perception and the result of many choices—
both artistic and technical. No technology can replace the inspired work of an
active imagination, though it can certainly help you to capture that vision.
Learning to create not only competent but visually arresting exposures then
is a matter of two things: learning to see the potential for dramatic exposures
in familiar situations, and then knowing how to achieve them with the right
combination of shutter speed, aperture, and ISO setting. The trick, of course,
is to learn to master both of these skills so that you can apply them
instinctively, consistently, and effortlessly.
