Spot metering, английский
- The camera`s auto exposure system is focused on a very small area in the center of the viewfinder to critically adjust the overall exposure value only for that area. see also: center-weighted and matrix metering
- Spot metering is the measurement of very small portions of the total image area. older cameras, as well as less-expensive digital cameras, only offer a single, centrally located measuring point, usually between 1 to 5 degrees in coverage. many newer cameras offer a selection of 3, 5, 7, 11 or more reference points for selective metering, which enable you to selectively measure important areas of the photograph, including areas that are off-center to the frame. spot metering is a very effective way to take readings of backlit subjects.
- Taking an exposure reading from a very select portion of the frame. cameras with built-in spot metering indicate this portion with a circular ring in the viewfinder screen. some spot meters have coverage as broad as 8-degrees (this might also be called selective field metering) or, with a handheld spotmeter, as narrow as 1-degree. many incident meters now have spot metering options. spot metering is always a reflected light reading, thus is subject to that type of meter`s failures.
- The camera’s auto exposure system is focused on a very small area in the centre of the viewfinder to adjust the overall exposure value just for that area.
- In photography, a method of calculating exposure whereby only a tiny point of the scene is taken into account.
Slr - single lens reflex, английский
Slr single lens reflex means the camera has a viewfinder that sees through the lens (ttl) by way of a 45°-angled mirror that flips up when the shutter fires and allows the light to strike the image sensor (or film).
