ABSTRACT:
A compact strobe is adapted for direct connection to a Polaroid SX-70 Land Camera or the like. Once the strobe is connected to a film laden camera, it is provided with a steady state input voltage which can be utilized by the strobe to charge a storage capacitor. The storage capacitor may thereafter be triggered at an appropriate time during the camera exposure interval by a select trigger signal, also furnished from the camera, to discharge through a flash tube thereby providing a source of artificial illumination. Connection from the camera to the strobe is made from the flash array receiving socket on top of the camera exposure housing as well as from the remote actuator button socket on the side of the camera exposure housing. To accommodate this connection, the strobe is provided with both a blade connector similar to that utilized on a conventional multilamp flash array and a flexible electrical connecting member for connecting directly to the remote actuator button socket.
