Abstract

A method for surveying light conditions upon photographing by storing the intensity of light at a certain moment and indicating the same as a reference value and that deviations from said reference value is detected and indicated after said detection moment. The present invention also relates to a device for surveying the light conditions upon photographing, including a detector (6, 29) for detecting light intensity. The device includes means (35) for storing information about the light intensity at a certain moment and means (35, 8) for detecting and indicating deviations from said light intensity after said detecting moment.
