Portrait mode widens the aperture to throw the background out of focus (see Bokeh). The camera may recognize and focus on a human face. The camera may recognize and focus on a human face. Night portrait modes use an exposure long enough to capture background detail, with fill-in flash to illuminate a nearby subject.
A Nikon-style mode dial showing aperture priority mode.. Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a mode on some cameras that allows the user to set a specific aperture value while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter.
The Mavica electronic still camera recorded FM-modulated analog video signals on a newly developed 2" magnetic floppy disk, dubbed the "Mavipak". The disk format was later standardized as the "Still Video Floppy", or "SVF". The Canon RC-701, introduced in May 1986, was the first SVF camera (and the first electronic SLR camera) sold in the US.
The Canon EF 135mm f / 2L USM is a short-to-medium telephoto lens.The "135/2" is mainly used for portrait photography and for indoor sports, where the lighting is often poor. . The fast f /2 aperture makes the lens ideal for both of these applicati
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 / ...

Very-large-aperture lenses designed to be useful in very low light conditions with apertures ranging from f/1.2 to f/0.9 are generally restricted to lenses of standard focal length because of the size and weight problems that would be encountered in telephoto lenses and the difficulty of building a very wide aperture wide angle lens with the ...
Photographers can use the lens scales to work backwards from the desired depth of field to find the necessary focus distance and aperture. [38] For the 35 mm lens shown, if it were desired for the DOF to extend from 1 m to 2 m, focus would be set so that index mark was centered between the marks for those distances, and the aperture would be ...
