How to set exposure compensation for Canon digital camera?

Exposure compensation is an exposure control method, which is generally about 2 to 3EV. If the ambient light source is dark, you can increase the exposure value (such as+1EV, +2EV) to get the correct exposure. Exposure compensation is a shooting method that consciously changes the "appropriate" exposure parameters automatically calculated by the camera to make the photos brighter or darker.

How to judge the correct exposure

When taking pictures with Canon digital SLR camera, the easiest way to judge whether the exposure is ready is to judge whether the exposure is correct directly through the histogram when browsing the photos through the LCD screen behind the fuselage. For histogram, many friends who are beginners in photography are very confused after reading it. How to judge the exposure by histogram?

Correct exposure histogram

Mastering the histogram is actually not complicated. The leftmost part of the histogram represents the darkest part, and the rightmost part represents the brightest part. The histogram of correct exposure should be reasonably distributed between bright and dark ends.

Underexposure histogram

The histogram of underexposed photos is mainly concentrated in the area that represents the dark part on the left, and it can be judged whether the photos are slightly underexposed or seriously underexposed by distribution.

Overexposure histogram

The histogram of overexposed photos is mainly concentrated in the area representing the bright part on the right. The density of histogram distribution can be used to judge whether a photo is slightly underexposed or seriously underexposed.

Rational use of exposure compensation

When shooting at ordinary times, you can judge the exposure of photos at any time by histogram, but some shooting environments, such as backlight and indoor scenes, sometimes display the histogram with correct exposure, but the subject is still underexposed. At this time, exposure compensation is needed.

When shooting in backlight, the characters are underexposed.

By increasing the exposure compensation of EV value 1, accurate exposure can be obtained.

The picture above shows the model shot in reverse light. When the camera is exposed normally, due to the influence of ambient light and camera metering system, the photos taken are often seriously underexposed, but the exposure to the surrounding environment is accurate. At this time, the camera exposure compensation can be set according to the light of the shooting environment, so as to improve the exposure compensation to obtain accurate exposure of the shooting object.

A Special Form of Exposure Compensation —— Surrounding Exposure

Enclosed exposure mode is used for beginners of photography, but for friends who are not skilled in setting exposure compensation. If bracketing exposure is selected, the camera will take three consecutive photos with less than one exposure, normal exposure and transition exposure.

Try to shoot in the peripheral exposure mode to ensure that the shooting positions of the three photos are the same.

Enclose the three photos taken in exposure mode, from left to right.

Underexposure, normal exposure, overexposure

When shooting in complex light, if the exposure control is not good, you can choose to use the method of surrounding exposure, and adjust the exposure according to the level difference of 1/3EV, 1/2EV, 1EV, etc. The exposure of each photo is different, so you can choose a satisfactory one from a series of photos.
