Iris Lock; Backlight Compensation; Spot Exposure Control - JVC GR-DA30U Manuel D'utilisation

Iris Lock

Like the pupil of the human eye, the iris
contracts in well-lit environments to keep too
much light from entering, and dilates in dim
environments to allow in more light. 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 changes),
such as when the subject is backing away.
• When shooting on a refl ective natural
background such as at the beach or when
skiing.
• When shooting objects under a spotlight.
• When zooming.
