Backlit environment is the most common shooting environment in the shooting process, many masters say that photography is the shaping of light and shadow, and many photographers believe that only backlight is king, "backlit out of the blockbuster", many excellent photography works are backlit environment shooting, next, the author photography lecturer Yu Peng will share with you when shooting backlight, how to carry out exposure compensation settings, how to accurate metering and precautions when shooting backlight.
Exposure compensation
Exposure compensation is the most common technique when shooting backlight, generally according to the strength of the background light to set, in the av file (aperture priority) camera original metering on the basis of increasing the exposure of about 1 ~ 2ev, the subject can get a more appropriate exposure.
This is the most versatile way to take backlit photos, as SLR cameras all have exposure compensation. In addition to the above methods, the implementation of exposure compensation can also be achieved indirectly by increasing the iso value / reducing the shutter speed in the m (full manual) file mode, and the advantage of increasing the iso to is that it is not necessary to change the amount of light entering per unit time, thereby maintaining the initial value of the shutter, but reducing the image quality; and reducing the shutter speed It is worth noting that the safety shutter is guaranteed.
Exposure lock
In order to obtain the appropriate exposure of the subject in complex situations such as backlighting, we can also use the camera's exposure lock function, the specific method is as follows: first change the lens focal length to the longest end, and try to enter the subject as high as possible for metering, and then lock the exposure value measured at this time, and then leave the subject, recompose the picture as needed, and shoot, so that the subject can get the appropriate exposure.
Reasonable metering
Most SLR digital cameras also have a spot metering function, in order to get the appropriate exposure of the subject, in the backlight shooting, it is best to fold the point metering function, the shooting subject of the appropriate area for accurate metering (such as shooting the face when shooting the person, in addition to the focus to select the eye).
In addition, you can use a separate light meter to accurately meter close to the subject, and then shoot in full manual mode based on the metering value.
Precautions
The situation of backlit shooting is more complicated, although the use of the previous method can get the ideal shooting effect we want to achieve, but we should still pay attention to the following points:
When taking important photos in the case of complex lighting, you can use the bracketing shooting method, that is, take multiple photos with underexposure, normal exposure and overexposure respectively.
When shooting backlit, be sure to use a hood, and try to avoid strong direct light to the lens to avoid flare.
For some backlit photos with exposure errors, they can be repaired by using photoshop, lightroom and other image processing software in the later stage.
If you shoot special effects such as silhouettes, you can shoot according to the exposure value determined by the camera, and no special measures are necessary.
The quality of the backlit shooting effect, in addition to the shooting technology, largely depends on the quality of the camera lens, such as the quality of the coating technology.
In short, one of the more difficult shooting techniques to master when shooting backlighting, I hope that everyone will try and practice more, in order to master more solid shooting techniques in practice and shoot better works.
