Abstract
An automatic strobe apparatus for use with a diaphragm-shutter of the type having a programmed mode of operation operates to automatically control the amount of light provided therefrom. The automatic strobe apparatus provides the maintained proportion of illumination light contributing to film exposure under conditions of the level of ambient scene illumination light intensity higher than the first level for the maximum exposure interval allowable for an exposure without incurring blurring effects from camera shake and under conditions of the level of ambient scene illumination light intensity lower than the second level for substantially no proportion of ambient scene illumination light contributing to film exposure when the maximum exposure interval is given. On the other hand, the automatic strobe apparatus provides an increased amount of artificial illumination light for the compensation of the lack of the amount of ambient scene illumination light contributing to film exposure under conditions of the level of ambient scene illumination light intensity between the first and second levels.
