ABSTRACT:
The disclosure is concerned with an electronic flash module comprising a plurality of flash subunits to illuminate a photographed scene in flash photography. Each flash subunit comprises a flash-tube and associated charging and triggering circuits; a modeling lamp to allow a photographer to set up the lighting pattern. Each module comprises a trip circuit to synchronously trip all the triggering circuits in the module. It is preferred that the module further comprises a photosensor to activate the trip circuit upon sensing a trigger pulse sent out by a remote device. Preferably, the module comprises connection means so that two or more modules can be linked up to form a panel with a larger illuminating source area. Furthermore, it is preferred that the flash subunits can be selectively and individually disabled to allow the photographer to adjust the illuminating pattern.
