In photography, integrating is a method of determining the correct exposure by averaging the light readings from both the bright highlights and the shadowed areas of a scene. This technique helps achieve a balanced exposure that preserves detail across the full tonal range of the subject.
Integrating exposure is particularly useful in high-contrast situations, such as outdoor landscapes with bright skies and dark foregrounds, or in studio photography with mixed lighting. Understanding this method allows photographers to make more accurate exposure decisions, resulting in images with well-preserved detail and natural-looking tonal balance.
