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
A system that allows "dialing-in" or adding or subtracting evaluation values (EV) for a given image. Compensating involves deciding whether or not the metre reading is under or over exposing and correcting the error. This method allows bringing out details in dark zones or lessening the intensity of bright zones, raising image quality.
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
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
The distance from the rear model plane of a lens to the focus when the lens is focused at the infinity position.
Industry:Consumer electronics
This occurs when a digital image is artificially sharpened. The term usually refers to a white fringe that is apparent on the edges of objects in the picture. Fringing can also occur as a result of compression.
Industry:Consumer electronics
The number assigned to a particular lens aperture (or opening) size.
Industry:Consumer electronics
The most recent GIF standard that allows the selection of area for transparency. The primary use is on the Internet and other on-line services. Like GIF it is 256 colour or 8 bit imaging.
