An image capturing apparatus includes an optical system, an image capturing unit, a posture detection unit, and a control unit. The optical system forms an image of a light beam from an object. The image capturing unit obtains image data corresponding to the light beam by the optical system. The posture detection unit detects a posture of the image capturing apparatus. The control unit determines based on the posture whether the image capturing apparatus is in a mode to perform shooting in a state in which an optical axis of the optical system faces a zenith or in a mode to perform shooting in a state in which the optical axis of the optical system faces a photographer side. The control unit changes control in a shooting operation using the image capturing unit in accordance with a result of the determination.
