Abstract
An exposure system for a camera includes a light emitting apparatus for emitting an artificial light toward an object. The light emitting apparatus is capable of selectively emitting a first type of light which flashes instantaneously, and a second type of light which flashes for a prolonged period of time. The intensity is maintained constant during the prolonged period of time. A camera produces a mode signal for switching the light emitting apparatus between a first mode in which the instantaneous flash light is emitted and a second mode in which the prolonged flash light is emitted.
