BLC (BACKLIGHT COMPENSATION)
Options: OFF, ON
The backlight compensation feature can be used to eliminate the effect of an area of strong
background lighting in a scene. If a strong background light such as a window exists in a
scene, the camera will try to compensate for it by reducing the overall exposure. This
would mean that the areas surrounding the window would become too dark.
By using the backlight compensation feature, it is possible to select areas of the scene
which may be used to control the exposure. Typically, the object of interest lies in the centre
of the scene and this is the area normally used to calculate the exposure. The edges,
where strong backlighting is likely to be, are ignored.
To facilitate backlight compensation, five windows are provided: Top, Left, Centre, Right
and Bottom. The BLC menu allows you to alter the size and position of the centre window.
The other four windows occupy positions around the centre window at the top, bottom, left
and right of the scene. Their size is determined by the size and position of the centre
window.
Note that these peripheral areas may not always be present. For example, if the size and
position of the centre window has been adjusted so that it includes the extreme left hand
side and bottom areas of the scene, then the Left and Bottom windows will not be available
to the user until the size and position of the centre window is readjusted.
