Generic mode dial for digital cameras showing some of the most common modes. (Actual mode dials can vary; for example point-and-shoot cameras seldom have manual modes.) Manual modes: Manual (M), Program (P), Shutter priority (S), Aperture priority (A). Automatic modes: Auto, Action, Portrait, Night Portrait, Landscape, Macro. A dial with more modes

Most dSLRs and mirrorless cameras have a few manual settings and a small sample of automatic modes. On point-and-shoot cameras, all manual control may be condensed into one mode (e.g. ASP, for Aperture priority, Shutter priority, Program) or may be completely absent. Many compact cameras show a large array of scene modes.
Hardware and software ("firmware"), built into the camera, measures luminance of the subject and automatically sets shutter speed, lens aperture or sensitivity; this also allows the camera to set the aperture for manual lenses fixed with an AE chip.

Guide number distances are always measured from the flash device to the subject; if the flash device is detached from the camera, the position of the camera is irrelevant. Furthermore, unless a flash device has an automatic zoom feature that follows the setting of a camera's zoom lens, guide numbers do not vary with the focal length of lenses.
Detail of front of Kodak Retina Ib 35mm camera (c. 1954) showing the EV setting ring that couples aperture and shutter speed settings A Kodak Pony II camera (1957–1962) with exposure value setting ring. This camera has a fixed shutter speed, so the "EXP VALUE" ring simply sets the aperture.
Motion pictures make limited use of aperture control; to produce a consistent image quality from shot to shot, cinematographers usually choose a single aperture setting for interiors (e.g., scenes inside a building) and another for exteriors (e.g., scenes in an area outside a building), and adjust exposure through the use of camera filters or ...
Sunlit subject shot on a digital camera set to ISO 100, exposed at f/8 at 1/400 second which is the same exposure value as f/16 for 1/100 second, the recommended "sunny 16" exposure In photography, the sunny 16 rule (also known as the sunny f /16 rule ) is a method of estimating correct daylight exposures without a light meter .
