ISO
Light Sensitivity
What ISO denotes is how
sensitive the image sensor is to
the amount of light present. The
higher the ISO, the more
sensitive the image sensor and
therefore the possibility to take
pictures in low-light situations.

However, all this increase in
sensitivity does not come free.
There is a price to pay with your
image appearing more noisy.
An image sensor is usually
calibrated so that it gives the
best image quality (greatest S/N
ratio) at its lowest possible ISO
speed. For most consumer
digital cameras, this value will
be expressed as ISO 50, ISO
64 or ISO 100. A few digital
cameras use ISO 200 as their
lowest ISO speed.
