Manual override control (exposure correction)

Exposure meters are calibrated to a standard grey (18% reflection) value for an average photographic subject. If the subject does not conform to this standard, manual override correction of the exposure-meter reading becomes necessary.

Manual override is more often necessary with full-field integral exposure metering. In selective mode, the more limited metering field makes it possible to measure a representative detail with an average grey value, thus ensuring accurate measurement.

Example for "plus" (+) override correction For a very brightly lit subject, such as snow, sand, or water, the high reflectivity causes the exposure meter to indicate too short an exposure. The snow itself is likely to appear grey, people much too dark: underexposure. To correct this, the time of exposure must be increased, i.e. set the override control to +2.

Example for "minus" (-) override correction For a very dark subject that reflects only a small amount of light, the exposure meter indicates too long an exposure. A black car appears grey: overexposure. The exposure time must be reduced i.e. set the override control to -1.

To set the override control, press the locking button [14] and turn the setting scale [15] to the required value by lever [16]. To lock the button [14], press it in and turn it anticlockwise. When the override control is at 0, the lever [16] fits snugly into the camera body. The override control can be set in steps of one-half of an exposure value, from Ev +3 to Ev -3. When

override is active, the symbol flashes at bottom left in the viewfinder.
