Talk about camera metering and skills in

Talk about camera metering and its skills in light of light, the intensity and the color is different, to think in these complex environmental light shooting out and actual light environments are the same, but the exposure correct photos, you need to use the correct metering techniques to determine how to set the camera to aperture, shutter, white balance and Flash. Metering and metering programmes on digital camera and its skills in metering light irradiation direction, intensity and color is different, to think in these complex environmental light shooting out and actual light environments are the same, but the exposure correct photos, you need to use the correct metering techniques to determine how to set the camera to aperture, shutter, white balance and Flash. Metering and metering scheme comes to use the correct metering modes and skills, we first need to understand what is a digital camera metering. The so-called metering actually refers to a digital camera based on the ambient light system relies on a specific measure and the aperture/shutter speed combination. Simply put, that is to be taken of the objects affected by the measure of light conditions. In General, the metering largely reflected the determination is subject to the brightness of the lens and then according to the brightness to a certain combination of aperture and shutter speed. While this is generally the way light called reflective light. And metering mode if you press the metering component placement can be divided into different then the external metering and inner light. And so-called external metering the metering components and optical lens and independently carry out metering. This metering methods widely used various paraxial viewfinder type lens shutter camera, although it has sufficient sensitivity and accuracy, but in many cases, but because the lens and metering component location and photographic differently and produce. At present, many consumer-level digital cameras use the metering system for metering. And so-called inner light General also called TTL TTL Light metering, i.e. Measuring. This metering mode is normally measured by the camera directly into the lens of the amount of light, and light metering mode than it can be more flexible in the replacement-phase distance lens or camera, plus color filter for automatic light correction. At present almost all of SLR digital cameras and associate professional digital cameras have this metering mode. And in the inner light, metering component placement mainly two scenario: one is placed in the viewfinder eyepiece near in the light path, the metering mode called TTL General metering; second place in photo light path, the light from the secondary reflector or the film plane, focal plane shutter blade surface reflection to metering components on metering, spot metering mode called TTL direct. In General, TTL flash metering system in General with the traditional SLR camera metering system compare similar with accurate color reproduction, image features elegant, and TTL direct metering, multiple is applied to a variety of consumer-grade access professional camera, in comparison with TTL General metering, this direct metering can be good and poor color CCD tolerance and avoid excessive image color contrast. But whether using the metering programmes, professional point of digital cameras are very likely to have a variety of metering mode. The metering mode, if in the light metering components for photography within the scope of the regional scope of different measurement to classification, mainly including the point of metering, Center-section metering, Center weighted average metering, average metering mode, number of zone metering, and several other categories. But regardless of the metering mode, its aim is to hope that the photographer can more freedom on the basis of the actual environment to accurately determine the correct exposure. Metering mode of classification and its application skills A, point metering:

Generally speaking, in this mode metering components only very small measuring screen Center.

Photography, camera lens was taken more than once at the main parts, one by one to measure the brightness, and finally by the photographer in accordance with the data determines exposure parameters. Most of the metering mode is applied to the photographer want to shoot subjects full performance. For example, in the light of uniform shadow Interior shooting people, many photographers will use point metering mode on the character of the important parts, such as eyes, face, or have characteristics of clothes, physically for metering, focus on performance characteristics of its position, in order to achieve the outstanding theme artistic effect. (Figure 1, the use of spot in indoor MM eyes for metering of effects) and some high-end digital camera also has a so-called multi metering mode, in fact, is the point of metering, but this metering mode will become a single point in the viewfinder of multiple points, the photographer can more freedom for metering point selection for exposure. But note that this way of metering is not suitable for ambient light complex, in particular the backlight or contrast greater use, as in Figure 2, because the images photographed with sky and mountains two contrast of larger objects, while the photographer and use a metering mode, only the sky for metering, allows the camera to the light-exposed due to the mountains of detail is lost.
