While you usually want to get
good exposure on most subjects throughout the frame, there are times when a
silhouette can add dramatic impact to an image. For our purposes, a silhouette
is an almost graphic form within the scene that shows no detail. It can be
recognizable or abstract, but it should play a part in the scene that makes it
a strong visual element.
While you should generally
avoid making images that have you pointing the camera at the sun, a silhouette
is created by doing just that. The difference is that the silhouetted form
should block the direct rays of the sun, yet your exposure reading should be
made off the background, not the foreground silhouetted subject. If the light
in the background is bright enough and you avoid the foreground in your
exposure reading, you can be assured that the foreground will become
silhouetted. This is best accomplished using a spot metering pattern.
Settings: With a 210mm lens:
at ISO 200, f/22 at 1/500 second. Spot exposure reading made and locked off the
bright background.
