Light metering device for panorama photography

摘要

The light metering device has a pair of light intensity detectors (3a,3b) for measuring the light intensity level for respective measuring ranges (4a,4b), corresponding to the incident light for a pair of panorama zones (10a,10b). The light intensity signals provided by the detectors (3a,3b) are fed to an evaluation circuit determining the difference between them for controlling a display. Pref. the light intensity detectors are positioned behind a toroidal curved diffusor (4), with a light screen (5) inserted inbetween the detectors. The light metering device can be fitted to a panorama camera via a mounting foot.
