2BLUE TRIANGLES
These church spires show strong
form, as well as shape, thanks to
the sidelighting. But the close
crop creates an almost abstract
composition of triangular shapes
in differing shades of blue.
4THEATRICAL POSE
With the right pose, the human
figure can convey a wide range of
expressions and feelings even when
seen in silhouette. In this case, the
dark outline of a woman is actually
a statue, deliberately placed to look
plaintively out to sea.

2LIGHT AND DARK
In low-key shots where dark tones
dominate, the eye is automatically
attracted to any bright area within
the image. In this case, the viewer
is drawn by the sunny reflections
on the water—and the contrasting
jet-black silhouettes of boats that are
found in this area of position.
RAW DEAL
An advantage of digital is that
you can see if your shot has
worked before you move on.
This is useful for checking
exposure with tricky subjects
such as silhouettes. But this
approach does not work when
the subject or lighting might
change between shots. Some
cameras offer a special RAW
shooting mode. This allows
you to tweak exposure, color
balance, and so on, at a later
date, using puter—with
no loss in image quality. This
facility is handy when you are
uncertain about exposure.
2SOFT CIRCLES
Some shapes are more attractive
to the eye than others. Circles work
particularly well within pictures,
because the rounded edges contrast
peacefully with the angular edges
of the frame. In this shot, it is the
bright color of the oil drum in
the foreground that draws the eye
into the picture’s pattern.
