Features

This mode can be selected for general use at all times.

Depending on the light distribution in the composition,

metering is carried out

as follows:

When the central part of the composition is darker than

areas on the periphery, the camera computer increases the

exposure to compensate according to the degree of differ-

ence in brightness indicated.

When the central area is brighter than the rest of the com-

position the camera sets a predetermined compensation

value to reduce the exposure.

When the sun or other extremely bright light sources ap-

pear directly in the composition they are ignored in making

the exposure calculation.

When the whole composition is illuminated evenly the

camera operates in the same way as in TTL Direct

"OTF" Auto Mode (using center-weighted average

metering). In this case the ESP Metering symbol

does not appear.

1. This mode should be selected when you do not want to

leave everything up to the camera, but prefer to set the ex-

posure according to your own experience, 'feel' and crea-

tive requirements.

2. In this mode the

camera decides the exposure by taking an

average (center-weighted) of the brightness of the overall

composition, without analyzing light distribution in differ-

ent parts of the composition.
