This camera has a fixed shutter speed, so the "EXP VALUE" ring simply sets the aperture. On most cameras, there is no direct way to transfer an EV to camera settings; however, a few cameras, such as some Voigtländer and Braun models or the Kodak Pony II shown in the photo, allowed direct setting of exposure value.
Digital cameras can achieve similar results (high dynamic range) by combining several different exposures (varying shutter or diaphragm) made in quick succession. Today, most cameras automatically determine the correct exposure at the time of taking a photograph by using a built-in light meter , or multiple point meters interpreted by a built ...
The life-expectancy of a mechanical shutter is often expressed as a number of shutter cycles. Most digital cameras save the shutter cycle information along with the photos, which contains valuable information such as shutter speed, aperture, and shutter count. [12] There are multiple websites and applications to access the EXIF data.
The shutter speed dial of a Nikkormat EL Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects. In photography , shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera 's shutter is open) when taking a ...
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 .
Cameras with focal-plane shutters—even if they had PC connectors with X, F, M, or S-sync delays ("xenon sync" with zero delay and flashbulbs with peak delays of 5, 20, and 30 ms)—could not be used at speeds that attenuated guide numbers with most types of flashbulbs because their light curves were characterized by rapid rise and fall rates; the second shutter curtain would begin wiping ...
The f-number N is given by: = where f is the focal length, and D is the diameter of the entrance pupil (effective aperture).It is customary to write f-numbers preceded by "f /", which forms a mathematical expression of the entrance pupil's diameter in terms of f and N. [1]
More sophisticated cameras have the match-needle instrument coupled directly to aperture and shutter speed setting rings on the lens tube instead to a separate analog calculator. This is the most convenient way of match-needle instrument usage, especially when the meter's scale is mirrored into the viewfinder.
