摘要：
The invention relates to a method for a non-retarded shutter release of a rotary sector shutter, particularly for use in photogrammetrical aerial cameras comprising a computer means which via a control means for rotating the rotary sectors of the shutter sets the latter to a rate of rotations in a manner that the time of photograph sequence is a multiple integer of the time interval between two feasible open times of the shutter. Probable incorrect exposures are eliminated by a variation of the diaphragm setting.
