In questo tipo di misurazione, un punto centrale del telaio viene utilizzato per misurare la luce che è venuta fuori tema. Il misurazione spot è spesso indicato dal mirino della fotocamera. Utilizzato senza cura, questo sistema può provocare facilmente dosabile zona essendo ben esposta, mentre il resto del telaio è sotto o sopra esposta.

Red-eye is the term used to describe the effect that can occur in photographs where the pupils of the eyes can take on a red color. The red color appears when the pupil of the eye is dilated, usually in a low light environment when the light of the flash strikes the retina at the back of the eye, reflecting the light through the wide-open pupil. (Also see Red-eye Reduction)
Industry:Consumer electronics
A system that causes the pupils of a subject to shrink by shining a light prior to the taking of the flash picture. This prevents the red-eye effect.

A reflex camera is one that utilizes a mirror system to reflect the light, and therefore the image, coming through the lens, to a visible screen. The image seen in the camera's viewfinder then is the same image entering the lens. This system provides the most accurate framing and focusing. Most reflex cameras reveal a high percentage of the image that will be photographed, upwards of 80%. Some reflex cameras are able to show 100% of the image frame into the viewfinder. The reflex system avoids the parallax problem that plagues most direct view cameras. See also SLR.

Refers to the number of pixels, both horizontally and vertically, used to either capture an image or display it. The higher the resolution the finer the image detail that can be seen.
Industry:Consumer electronics
A mechanism in the camera that controls how much light reaches the film.

The length of time the shutter remains open when the shutter release is activated, expressed in fractions of seconds.
Industry:Consumer electronics
The difference between elements in a photograph. Contrast can include the difference between light and dark areas, or a marked difference in colors.
Industry:Consumer electronics
The zone of in-focus elements, from front to back. Another way to put this is the range of distance that is acceptably sharp within a photograph. Depth-of field varies inversely with the aperture opening. In other words, a wide-open lens with an aperture of f/1.8 has little depth of field; if stopped down to f/16, almost everything from front to back will be sharply in focus.
