Dawn
is the time before the sun has risen - It is a time when there is enough ambient
light in the sky for us to see
colours. This is often also called twilight. It is a time
when the diffused light from the sky during early morning when
the sun is below the horizon and its light is refracted by the
earth's atmosphere. As the sun begins to rise and the light gains
in intensity from darkness, we begin to see with greater definition
and a wider range of colours. How long the dawn light lasts depends
upon your position on the earth and the time of the year. In summer
it is longer in winter shorter.

As
the sun rises it lights up the underside of clouds in the sky.
The higher these clouds are in the sky the earlier the light strikes
them. The light from these clouds reflects down onto the landscape
creating an enchanting diffuse light with no shadows or high lights.
