On a sunny day at ISO 100 ("100 speed film"), the aperture is set to f /16 and the shutter speed (i.e. exposure time) to 1 / 100 or 1 / 125 [2] seconds (on some cameras 1 / 125 second is the closest available setting to 1 / 100 second). On a sunny day at ISO 200 and aperture at f /16, set shutter speed to 1 / ...
S or Tv: Shutter priority or Time value enables manual control of the shutter speed, and aperture is calculated by the camera for proper exposure (given an ISO sensitivity). M: Manual mode both shutter speed and aperture are independently set manually (with ISO sensitivity also set manually), where proper image exposure requires accurate manual ...
The set EV could be locked, coupling shutter and aperture settings, such that adjusting either the shutter speed or aperture made a corresponding adjustment in the other to maintain a constant exposure (Ray 2000, 318). On some lenses the locking was optional, so that the photographer could choose the preferred method of working depending on the ...
An approximately correct exposure will be obtained on a sunny day using ISO 100 film, an aperture of f /16 and a shutter speed of 1/100 of a second. This is called the sunny 16 rule: at an aperture of f /16 on a sunny day, a suitable shutter speed will be one over the film speed (or closest equivalent).
Sensitivity priority automatic exposure mode, where the photographer sets the ISO sensitivity and the AE firmware sets the aperture or shutter speed. TC Teleconverter. A lens accessory that fits between the lens and camera body and extends the focal length of the lens, often by 1.4x or 2x, at the cost of reduced light, decreased image quality ...
An example of the use of f-numbers in photography is the sunny 16 rule: an approximately correct exposure will be obtained on a sunny day by using an aperture of f /16 and the shutter speed closest to the reciprocal of the ISO speed of the film; for example, using ISO 200 film, an aperture of f /16 and a shutter speed of 1 ⁄ 200 second. The f ...
With the GE Synchro‑Press No. 11 for instance, a modern camera with a focal-plane shutter and X sync would require a shutter speed of 1 / 15 th of a second (67 ms) to obtain an even exposure across the entire image area—and a not-insignificant boost in the guide number by capturing all the luminous energy to the left of the 20 ms peak.
S or Tv: Shutter priority AKA "Time value" allows the photographer to control the shutter speed, while the aperture and ISO sensitivity are calculated by the camera. Sv: Sensitivity value allows the photographer to control the ISO sensitivity, while aperture and shutter speed are calculated by the camera (this is a Pentax DSLR feature)
