Abstract
A camera capable of photographing with flash comprises a pre-flash command circuitry 11 which commands a pre-flash used for curtailing red eye; rear synchronized photography command circuitry 25 which commands a rear synchronized photography; a microcomputer 22 which, when no command is being given to the pre-flash, and when rear synchronized photography is being commanded, causes a light discharge unit 24 to perform the primary flash with the first timing in response to the release of the shutter, and which when the pre-flash is being commanded, causes the light discharge unit 24 to perform the pre-flash prior to the release of the shutter, notwithstanding a command for synchronized photography, and; notwithstanding the existence or lack of a pre-flash command, if there is no command for rear synchronized photography, in response to the release of the shutter, causes the light discharge unit 24 to perform the primary flash with the secondary timing which is faster than the first timing; when both the pre-flash and the rear synchronized photography are commanded, the primary flash is accomplished with the first timing which is continuous with the pre-flash.
