Abstract
The invention relates to a system for simultaneously photographing two objects on a single instant film. Such systems are used in, for example financial institutions such as banks for simultaneously photographing a transaction document, such as a cheque, and the person related to the document, such as the person cashing the cheque. In accordance with the present invention, the camera of the system includes two separate lenses, each one receiving light rays bearing the image of a different one of the objects. Associated with each lens is a separate shutter mechanism, and the f opening or the shutter speed of each shutter is separately adjustable by means which are readily accessible to the camera operator. Thus, the shutters can be separately adjusted to take into account the different lighting conditions to which the separate objects are exposed.
