your aperture, a “stop” up or down lets in
twice as much or half as much light into
your sensor compared to the “stop” beside
it. Mastering Aperture is a key to well-developed images.

it also has a multiplier effect, which makes
the lens you are using 50% longer. So you

like an 85mm.
Shutter:
ISO:
The Shutter on your camera is a curtain
that opens and closes letting in light for
a specified duration of time. The quicker
the shutter opens or closes the less light
is let in. So on a sunny day at the beach
perhaps a shutter speed of 1/8000th of
a second is necessary. As the light dims
you need to adjust the shutter speed
to 1/500th or even 1/250th of a second. Some cameras can allow the shutter
to be open for hours. This is useful for
those middle of the night images of star
trails.
ISO is essentially the sensitivity to light
that your sensor is set at. So for example,
if you are photographing in brightly lit
conditions then an ISO of 100 is sufficient
because your camera does not have to
be sensitive to light. The light is already
present. But as the light deteriorates you
will need to bump up the ISO to become
more sensitive to the fading light.
Crop Sensor:
Usually when buying your first dslr, you’ll
buy a camera with a crop sensor. Meaning
that the sensor in your camera is smaller
than 35mm. But that does not only effect
