Exposure compensation in the practical application of photography.

Exposure compensation, for a shooting experience knows that, the quality of light on a pivotal film, photography is the calculation of light. .Shoot digital camera is both a tool, of course, is to calculate the light tool. .Because the objects in a different environment, making light, so how to control the exposure is essential. .Flash, reflectors and other natural very useful, the right to make <p> appropriate exposure compensation, for a shooting experience knows that, the quality of light on a pivotal film, photography is of light "computing." .Shoot digital camera is both a tool and, of course, that is "calculated" light tool. .Because the objects in a different environment, making light, so how to control the exposure is essential. .Flash, reflectors and other natural very useful, appropriate use of the correct exposure compensation is another effective way. .Now digital cameras are generally available commercial exposure compensation, adjustment range is generally about ± 2.0EV. .EV value, said exposure value, which reflects the aperture size and shutter speed combination. .EV value and the scene brightness and film sensitivity is also relevant. .In layman's terms, the faster the film speed, the brighter the subject matter, the greater the EV value, the corresponding time is necessary to use a small aperture and fast exposure. .</ P> <p> exposure compensation is to allow the photographer to determine the camera's exposure metering of the "quantity" to amend, adjust, and thus be suitable for the performance of the main correct and accurate exposure. .</ P> <p> volume with exposure compensation +3, +2, +1,0, -1, -2, -3, and so on to that "+" indicates exposure metering basis set .the increase in exposure, "-" indicates less exposure, the corresponding figure for compensation for exposure series, and we ordinary civilian compensation of digital camera usually within the range of ± 2. .</ P> <p> camera's exposure compensation is divided into positive (+) compensation and the negative (-) compensation of two, the camera used "+/-" symbols. .In short, the backlit photography, with the positive (+) compensation (or dark in the viewfinder than the standard for the meter) to properly show the details of the subject, blur the background, access to high-profile photo; with negative .(-) compensation (or in the viewfinder brighter at the metering standards) were given a silhouette effect, access to low-key picture, showing the relationship between light and shadow. .Such as the following diagram: </ p> <p align="center"> </ p> <p> was 4 pm in the sun, the light in fact very strong, unlike the photo light. .When shooting, I use aperture priority shooting method, negative (-) Two-step exposure compensation and then the clouds brighter place against the metering to be such a silhouette effect. .</ P> <p> shooting in backlight compensation method using the exposure photography, light is stronger, the greater the contrast the better. .Of course, the photographer should pay attention to use the hood, if the light is too strong, but also application of the object (hat) of a block in front of the camera block the sun, do not let the lens in direct sunlight, otherwise the pictures easy to leave the sun spot, destroy the beauty of the screen .affect image sharpness. .</ P> <p> let us look at Figure 2, Figure 3: </ p> <p align="center"> </ p> <p> basically the same point of view, Figure 2 is positive (+) two .the case file against the dark of the early details of metering and more of a picture, the overall picture seems relatively messy, while the opposite philosophy in Figure 3, I used the negative (-) Two-step exposure compensation to capture the .obtained silhouette effect, remove some unnecessary details, to better highlight the theme. .</ P> <p> from the above picture we can see the exposure compensation for the performance of the important role of the scene, some experienced photographers often use "white with black cut" before the exposure compensation to elaborate the essentials, .reflective because of various features of different rates, so the scope of compensation and no specific standards, so the photographer should develop a closer look at scenery, form of black, white, gray balance between the degree and rate of the habit of reflection, from thinking .and practice to grasp the essentials they need the exposure, shooting out the wonderful work. .</ P> <p> Finally, the photographer must be reminded that, after photography with exposure compensation law, do not forget to compensate for the value transferred back to the "zero", otherwise, back to the photo is not overexposed photo is underexposed .. .</ P> <p> </ p>.
