The camera needs more light, as it cannot match the human eyes in terms of sensitivity. When capturing an image at a location, the light can vary and this makes it necessary to adjust the camera settings. Without the right adjustments, the image can become overexposed or underexposed that can compromise the details and makes the image look rather unappealing. In sunny locations, the chances are high that the image gets overexposed.
For under-lit areas, the opposite holds true. Besides, simply altering the camera settings do not in any way help to capture the image with the right exposure. There are several ways by which these instances of inappropriate exposure can be avoided. It includes not only changing the camera settings but also subjecting the captured image to the various techniques used in professional picture editing. The following are some methods for correcting the exposure.
Recomposing the Image
Most of the issues related to an underexposed or overexposed image are caused mainly due to an inaccurate composition. Composition not only involves staging the camera and the subject in respect to it, but also making sure that the subject and its background are well lit. In case of interiors, overexposure can result from outdoor light from the open windowsills. Blocking the windows can prevent the light from entering, so that the frame does not include such light sources.
Using Fill Flash
Flash is particularly useful even in the outdoors too. In sunny backgrounds, usually, the subject is placed beneath a shade to prevent it from getting too much exposure to light. This can result in the background to become more exposed when the camera is adjusted to capture the subject. Using a fill flash can aid in such instances to light up the subject in the shade, so that it has a balanced exposure when compared to the background.
Correcting in Photo Editing
Even if all the in-camera settings have been correctly adjusted, it can still result in some areas to appear underexposed or overexposed. In such cases, subjecting the image to various techniques of professional picture editing can help in correcting the image to make it appear well lit. Advanced imaging software contains numerous tools and settings that can fully alter the exposure in an image. Using these techniques of photo editing in conjunction with the above-mentioned methods can help in getting a perfect shot with the right exposure values.
