Abstract
A light emitting apparatus that is capable of photographing a proper exposure image by utilizing light control performance of a flash at the maximum even in photographing under a minute flash emission amount. The light emitting apparatus is connected with an image pickup apparatus communicably. The light emitting apparatus includes a receiving unit and a sending unit. The receiving unit receives a request from the image pickup apparatus. The sending unit sends information about a first emission amount lower limit value that is settable by the image pickup apparatus as an emission amount lower limit value to the image pickup apparatus in a case where the receiving unit receives the request from the image pickup apparatus in a first emission mode in which light is emitted at a time of photographing with an emission amount set by the image pickup apparatus in a case where automatic light control is performed.
