ABSTRACT:
There is disclosed a photographic system incorporating a photographic apparatus of the type including an exposure control system which senses and evaluates ambient and infrared spectral energy for controlling camera functions; as well as an accessory for use in combination therewith which compensates for attenuation of infrared energy underwater which infrared energy would otherwise be used in controlling the camera functions. Provision is made for a supplemental source of infrared energy that is directed to such system for a time period and in an amount based upon an evaluation of reflected visible spectral energy from the scene.
