• a second selection unit configured to select a wireless communication mode in which communication with an illumination apparatus is performed using a communication unit configured to perform a wireless communication, and a non-communication mode in which communication with an illumination apparatus using the communication unit is not performed;
• and
• a control unit configured to perform control such that in a case where one of the second mode and the wireless communication mode is selected, selection is disabled of the other one of the second mode and the wireless communication mode.

An illumination apparatus removably connected to an image capturing apparatus, the illumination apparatus comprising:

• a first selection unit configured to select a first light emission mode in which an amount of light emission is automatically set by the image capturing apparatus, and a second light emission mode in which light emission is performed to be smaller than in the first mode;
• a second selection unit configured to select a wireless communication mode in which a communication with one other different illumination apparatus is performed via a communication unit configured to perform a wireless communication, and a non-communication mode in which a communication with any other different illumination apparatus via the communication unit is not performed;
• and
• a control unit configured to perform control such that in a case where either one of the second light emission mode and the wireless communication mode is selected, selection is disabled of the other one of the second light emission mode and the wireless communication mode.

A method of controlling an image capturing system including an image capturing apparatus and an illumination apparatus, the method comprising:

• performing a first selection process to select a first mode in which an amount of light emission of the illumination apparatus is automatically set and an imaging sensitivity is automatically set, and a second mode in which the amount of light emission of the illumination apparatus is automatically set and the imaging sensitivity is automatically set to be higher than in the first mode;
• and
• performing a second selection process to select a wireless communication mode in which a communication with one other different illumination apparatus is performed via a communication unit configured to perform a wireless communication, and a non-communication mode in which a communication with any other different illumination apparatus via the communication unit is not performed;
• wherein in the first selection process and the second selection process, in a case where either one of the second mode and the wireless communication mode is selected, selection is disabled of the other one of the second mode and the wireless communication mode.
