The adjustable aperture of the lens. It restricts the amount of light allowed into the camera. This term can also be applied to shutter types, i.e. iris diaphragm shutter, which is a set of interposing leaves, which open and close at a variable rate to produce a between-the-lens shutter.

Unlike an optical zoom, the digital zoom takes the central portion of the high-resolution sensor's image to achieve the effect of a zoom. This means that the existing data is not enhanced or added to, merely displayed at a lower resolution, thereby giving an illusion of an enlarged image. All PowerShot cameras utilize the superior optical zoom, which actually augments the data collected by the sensor, rather than merely creating the illusion that the image has been enlarged.

Exposure explains how light acts on a photographic material. The lens opening controls light intensity, while the duration is controlled by the shutter speed. A camera with autoexposure can automatically control the exposure. The same principle works with digital cameras where film is replaced by the CCD.
Industry:Consumer electronics
Random Access Memory, . A type of computer memory that can be accessed randomly. This is the fastest type of memory for the computer and the most expensive. There are several types of RAM.
Industry:Consumer electronics
The way an image is saved to a digital camera's memory. The . JPEG format that PowerShot cameras store digital images as is fast becoming an industry standard.
Industry:Consumer electronics
A piece of plastic with a light sensitive mixture spread on it.
Industry:Consumer electronics
The process where chemicals remove the unexposed silver on the film, then fix or stop the developing process and stop the negative's sensitivity to light. Now with PowerShot digital cameras, you are freed from the expense of film buying and processing.
Industry:Consumer electronics
The film's sensitivity to light. For example, an ISO 100 film requires twice as much light as an ISO 200 film.
Industry:Consumer electronics
An electronic device that produces a burst of light the consumer can use to produce more exposure on the film.
Industry:Consumer electronics
The distance from the rear model plane of a lens to the focus when the lens is focused at the infinity position.
