essential skills: photographic lighting
Introduction The choice, arrangement and design of a subject within the frame determines the effectiveness of its communication. Communication can be increased by having a better understanding of the camera and its controls. Careful consideration is advised when using technical effects. Images are about communication and content and not about technique. Technique should never dominate the image.
Exposure compensation Exposure compensation is used to correct tonal values that would otherwise have recorded as too dark or too light. It is also used to record detail in highlights or shadows when the brightness range of the subject is high. Exposure compensation can also be used for creative effect. The creative process of photography sometimes requires an exposure that is not correct to produce the desired result. The degree of compensation is only limited by the photographer’s imagination and the limitations of the film or image sensor. Interesting results can be achieved by purposely underexposing or overexposing regardless of SBR. Underexposure should be carried out in Adobe Camera Raw and not in camera when using a digital camera.

Silhouettes An image described as a silhouette is the dark shadow or outline of the subject against a lighter background. A silhouette can be created by backlighting the subject and reducing the exposure sufficiently to remove detail from the subject. Reducing the exposure by approximately two to three stops is usually required to record the subject as black (this can be achieved in Adobe Camera Raw when using the Raw file format).
