Canon EOS 50D Instruction Manual page 273

Rich color variations. Amazing natural patterns.
Flowers are the supreme subject of macro shooting,
and the ideal way to learn the basics of macro techniques.
Only the close-up power of micro photography is really capable of
revealing the tiniest details of petals, pistil, and stamens.
Try using a colorful blurred background or a hazy dreamlike foreground
to bring out the reality
of
this micro-scale world.
For instance, use an atomizer to create a fine mist that
resembles tiny drops of dew, bringing vivid freshness to
plants. Or, create an instant reflector
by
attaching a little
wrinkled aluminum foil (using the darker, duller back side)
to a piece of cardboard. Then take a little time to find the
best angle for brightest illumination.
