For example, f /8 lets four times more light into the camera as f /16 does. A shutter speed of 1 ⁄ 50 s with an f /4 aperture gives the same exposure value as a 1 ⁄ 100 s shutter speed with an f /2.8 aperture, and also the same exposure value as a 1 ⁄ 200 s shutter speed with an f /2 aperture, or 1 ⁄ 25 s at f /5.6.

The f-number is dimensionless and is usually expressed using a lower-case hooked f with the format f / N, where N is the f-number. The f-number is also known as the inverse relative aperture, because it is the inverse of the relative aperture, defined as the aperture diameter divided by focal length. [5]
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.
Macro or close-up modes tend to direct the camera's focus to be nearer the camera. They may shrink the aperture and restrict the camera to wide-angle in an attempt to broaden the depth-of-field (to include closer objects) – this last mode of operation is often known as Super Macro. Movie mode allows a still camera to take moving pictures.
PC: Prontor-Compur. A 3.5 mm coaxial camera jack named PC terminal, to synchronize external non-dedicated flashes (f.e. studio flashes), found on many more advanced camera models. Also may mean "Perspective Control" for a lens that has the ability to shift to tilt to control linear perspective in an image.

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. Apart from the ...
Windows Camera is an image and video capture utility included with the most recent versions of Windows and its mobile counterpart. It has been around on Windows-based mobile devices since camera hardware was included on those devices and was introduced on Windows PCs with Windows 8, providing users for the first time a first-party built-in camera that could interact with webcam hardware.
