The lens
hood can stop light coming into the lens at extreme
angles and being reflected inside the lens, also can
lower the contrast of the image. Compact camera
designs often include some degree of lens protection
in the camera design. For cameras with
interchangeable lenses, most lenses come either with
integral or accessory lens hoods.
When there are strong light sources - such as the
sun, you can get the familiar 'flare' spots on
images. Different lenses give different patterns of
flare; the shapes of the larger spots depend on the
shape of the lens iris, and the colors depend on the
glass and coatings in use. Normally you want to
avoid these effects, but occasionally they can add
interest - as they more often to in film or video
footage. A lens hood enables you to shoot 'contre-jour'
or towards the light source, so long as you keep it
outside the image area, without excessive flare.
This can produce some exciting results.
