ABSTRACT:
The present invention relates to a device for flash light photography and, more particularly, to a device for flash light photography for adjustable light stroboscope. A major feature of the present invention is that the adjustable light condition of the stroboscope is rendered to be adjusted, based on the film speed and diaphragm value, independently of each other. Thus, when the film speed is made high, the responsive distance for light adjustment is elongated.
