ABSTRACT:
In a camera capable of setting a flash bracketing photo-taking mode in which an amount of light emission by a flash device is increased or decreased by a desired amount with respect to a predetermined value for every shot to be taken using the flash device, a photo-taking operation of the camera is inhibited if a charge voltage of the flash device is lower than a predetermined voltage when the camera is set in the flash bracketing photo-taking mode. Further, in a camera capable of performing an FE lock function of setting an amount of light emission of a flash device for a photo-taking operation by making preliminary light emission from the flash device prior to the photo-taking operation, and capable of setting a flash bracketing photo-taking mode in which an amount of light emission by the flash device is increased or decreased by a desired amount with respect to a predetermined value for every shot to be taken using the flash device, information related to the FE lock function (information such as the amount of main light emission) is retained even if a charge voltage of the flash device is lower than a light emission enabling voltage when the FE lock function has been performed with the camera set in the flash bracketing photo-taking mode.
