On a number of cameras this is the default or standard setting. The camera measures the light intensity in several points in the scene and then combines the results to find the setting for the best exposure. The method of calculation can be different from camera to camera. The actual number of zones used varies widely, from several to over a ...
Sv: Sensitivity priority or ISO priority controls the Sensitivity value (ISO speed), with both shutter and aperture calculated by camera, similar to Program mode. This mode is found on some Pentax cameras; on many cameras (such as Canon and Nikon) this is not a separate mode, but instead is accomplished by using Program mode and manually ...
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 .
The standard specified the measurement of light sensitivity of the entire digital camera system and not of individual components such as digital sensors, although Kodak has reported [77] using a variation to characterize the sensitivity of two of their sensors in 2001.
The image has been deliberately overexposed by +1 EV to compensate for the bright sunlight and the exposure time calculated by the camera's program automatic metering is still 1/320 s. The purpose of an exposure meter is to estimate the subject's mid-tone luminance and indicate the camera exposure settings required to record this as a mid-tone ...
The 1964 ASA standard for automatic exposure controls for cameras, ASA PH2.15-1964, took the same approach, and also used the more descriptive term camera exposure settings. Common practice among photographers is nonetheless to use "exposure" to refer to camera settings as well as to photometric exposure.
White translucent photographic umbrella; a flash is shot inside the umbrella and the light is diffused onto the intended target; provides a soft, large light source. Sv: Sensitivity value. Sensitivity priority automatic exposure mode, where the photographer sets the ISO sensitivity and the AE firmware sets the aperture or shutter speed. TC ...
Once the sensitivity to light of the recording surface (either film or sensor) is set in numbers expressed in "ISOs" (e.g. 200 ISO, 400 ISO), the light emitted by the scene photographed can be controlled through aperture and shutter-speed to match the film or sensor sensitivity to light. This will achieve a good exposure when all the details of ...
