Full-Held integral mode

Most photographic subjects contain details

of varied brightness. The light reflected by

this type of subject has a mean grey value of

18%, i.e. it is the same as that of a standard

grey area that reflects 18% of the light it

receives (average grey value). This is the

calibration value for all exposure meters.

The full-field integral mode is suitable for

all subjects in normal light, with no ex-

tremes of light or color, and where the light

and dark areas are fairly evenly distributed

over the entire visual field. For this type of

subject, choose full-field integral mode.

Selective mode

This is the method of choice when the sub-

ject has a very wide brightness range and

the correct exposure of a certain detail is

particularly important.

The large central circle in the viewfinder

indicates the field covered in this mode, in

which the exposure meter measures only the

light reflected by the exact area of the

subject that you want to determine the

exposure. The field is the same size on all

focusing screens and for all lenses, what-

ever their focal length, and is clearly

marked in the viewfinder.
