What is the purpose of bracketing in photography?

Bracketing in photography refers to the technique of taking a series of shots of the same subject while varying one or more settings, most commonly the exposure levels. This method is particularly useful in situations where lighting is tricky or when precise exposure settings are essential for achieving the desired effect. By capturing multiple images with different exposure levels—typically one at the meter reading, one underexposed, and one overexposed—the photographer can ensure that they have at least one image that meets the necessary exposure criteria. This approach helps to avoid losing important details in highlights or shadows, making it a valuable tool for creating well-exposed images.

This technique is not about capturing different angles or enhancing lighting conditions, nor is it related to arranging photos in chronological order. Bracketing specifically addresses the challenge of exposure in photography, providing flexibility and a safety net for photographers to work with varying conditions.
