Multiple Exposure
Multiple exposure is a photographic technique in which a photographer captures two or more images of the same scene and combines them during post-processing. Rather than relying on a single exposure, this method allows photographers to blend multiple frames to achieve results that would be difficult or impossible to capture in a single shot. The technique has applications across various photographic genres, including portrait, still life, and landscape photography.
Focus Stacking
In the context of landscape photography, multiple exposure is frequently employed as a method for focus stacking. This specific application involves capturing a series of images where the point of focus shifts incrementally from the foreground to the background. By combining these frames, the photographer creates a final image with enhanced sharpness and greater depth of field than a single exposure could provide. This process ensures that elements at varying distances remain crisp and detailed, addressing the optical limitations of aperture and sensor size.
