The electronic shutter regulates the shutter speed and hence the duration of exposure of an image (exposure time). Short exposure times allow for sharper images of moving objects but require a larger amount of light striking the sensor, which can be achieved, for instance, through a larger aperture (lower iris value, F-number).
The slow shutter function, as opposed to the conventional shutter, allows for significantly lower shutter speed and consequently enables images to also be taken with low light or at night.
Automatic exposure is a method for regulating the exposure of cameras. Thereby the electrical current generated by incidence of light onto the sensor powers a mechanism, which carries out certain settings and adjustments such as the aperture, shutter speed, ALC, AGC etc. All this is done automatically without human intervention.
The abbreviation AE Presets stands for »Automatic Exposure Presets«. The AE Presets are preprogrammed and designed to deliver optimal picture quality under specific exposure conditions.
Dallmeier cameras offer seven different, application-specific AE Presets: Universal, Details 1, Details 2, Indoor/Shadow, Indoor, Fluorescent, Low Light.
