2. Description of the Related Art Conventionally, in this type of photographing apparatus, the program AE corresponds to one EV value on a one-to-one basis, but depending on the photographing purpose and subject, a specific shutter speed (or aperture value) It may be preferable to choose. Therefore, a camera having a plurality of program diagrams and switching and using them is known. However, in such a camera, when selecting a program diagram according to the purpose of photographing, there are many cases where it depends on experience and knowledge. Further, since there are various program diagrams, display means and input means for switching between them are required, and there is a problem that display and operation become more complicated than a single program. Therefore, in order to solve the above problems, a control method has been proposed in which the shooting mode of the camera is controlled by inputting shooting mode information coded by a bar code or an IC card, for example.
