Why do we need light meter?olympus stylus 770 sw battery

Modern camera's metering system is quite powerful, many people often ask, need to take a light meter around it? In some cases, light meter is indeed very important, so we'll see what the specific situation you will need to use.
 
We can think from several perspectives   
?The camera's metering system can only measure reflected light, and hand-held incident light meter and flash can be a measure function.       
?Reflective of the meter, the larger errors, often because of the subject material, color, one error, relatively speaking, the use of incident light meter metering mode would more accurately.       
?In commercial photography, the measurement of light than light, especially when compared with the flash of light is basically dependent on the light meter to carry out, if only the camera, it can only do through the adjustment of the results of the shooting, and no precise The light ratio at all.       
?In the dim light, the camera's olympus stylus 500 battery metering system failure, a relatively sensitive light meter, and often you can read the value.       
?In addition, the measurement angle meter can also be reached is very small, such as 1 degree, which is generally a "Spot" function beyond the reach of the camera.

On the use of meter

If you want to explore more in-depth, light meter can be summarized as five about the use of type. Such as flight photometry, near measurement method, the standard plate metering law.

However, for the novice to use light meter, the most important is the "incident light metering point" concept, which is mainly metering, the meter on the subject is near and will Metering Alignment point light source, light source may be natural light, it could be an instant flash light.olympus fe-350 battery

Meter for the professional photographer, is basically considered a useful device. Learning in the beginning, could be used to practice the scene suggested the light of speculation, to determine, with the light meter to see if the test point measurement mode, with the gap between their guess how much? This practice is often the case, is a very good experience, the will cultivate a sensitivity to light a scene. Over time, the speculation that the values ??in a variety of environments, even more than the value read by the camera, but also useful. To put it bluntly, the camera's reflective meter, only one reference (of course, the reference value is also important).

In addition, in light meter, and will soon be converted aperture, shutter speed, ISO value, which is the ability to develop their own as a tool for fast inference. Personally think that the photographer's ability, progress, from the many levels of training, these levels may be subtle, the book may not go to school, but later will be verified, it is to let you operate independently and quickly determine the nutrients!Digital Camera Battery
