HOW A DIGITAL
SLR WORKS
In a digital SLR camera, light passes through
the lens ( 1), then is reflected by the mirror ( 2)
and projected onto the focusing screen ( 3).
Passing through a condensing lens ( 4), the
image is transmitted via the pentaprism (5) to
the eyepiece ( 6) and the photographer’s eye.
When the photographer presses the shutter
release the mirror swings up and out of the
way (see arrow), and the shutter ( 7), which
functions as a small curtain, opens, allowing
light to fall onto the focal plane ( 8), where the
image is captured by the camera’s electronic
imaging sensor.

ADD ITIONAL ACCESSORIES
Depending on your digital SLR,
you might be able to use lenses
you already own. There are
additional flash options when
you need more flash power
than the built-in flash delivers.
