<p>Indicating apparatus for use in a camera having a battery and automatic exposure control apparatus is disclosed. The indicating apparatus includes an amplifier and a manually operative switch member which in a first position couples the exposure control apparatus to the amplifier such that the amplifier will energize a low light indicating lamp only when the scene brightness is unsuitable for film exposure. The switch is movable to a second position to connect the first amplifier to a battery by way of a voltage divider network such that the first amplifier will energize the lamp only if a potential of the battery is above a predetermined level.</p> |
