as when the subject is backing away.
• When shooting on a reflective natural background
such as at the beach or when skiing.
• When shooting objects under a spotlight.
• When zooming.

Like the pupil of the human eye, it contracts in well-lit
environments to keep too much light from entering, and
dilates in dim environments to allow in more light.

White Balance Adjustment

A term that refers to the correctness of colour
reproduction under various lighting. If the white balance
is correct, all other colours will be accurately
reproduced.
The white balance is usually adjusted automatically.
However, more advanced camcorder operators control
this function manually to achieve a more professional
colour/tint reproduction.
