Iris Lock

Use this function in the following situations:
• When shooting a moving subject.
• When the distance to the subject changes (so its size
in the LCD monitor or the viewfinder changes), such
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.
When the subject is close, keep the iris locked. Even
when the subject moves away from you, the image will
not darken or brighten.

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 color reproduc-
tion under various lighting. If the white balance is
correct, all other colors 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
color/tint reproduction.

the light source, the subject tint will differ depending on
the white balance settings. Use this function for a more
natural result.

retained even if the power is turned off or the battery
