Multi-exposure HDR capture

A photographic technique that combines multiple exposures of the same scene to represent a wider range of brightness than a single exposure can record.

Exposure bracketing: A camera technique that records several images at different exposure settings of the same scene. It supplies the differently exposed frames that multi-exposure HDR combines.
Dynamic range (imaging): The span between the darkest and brightest signal levels an imaging system can represent. HDR capture aims to extend the scene brightness span represented in the final image.
Single-exposure HDR: A high-dynamic-range image produced from one exposure, often using sensor data or computational processing. It seeks extended tonal range without combining separately timed captures.
Real estate photography: Photographic documentation of buildings and properties for sale, rent, or recordkeeping. Bright windows and dim interiors often exceed a single exposure's useful range.
Exposure value: A logarithmic measure of photographic exposure based on aperture and shutter time. Bracket spacing determines how much additional brightness range each capture contributes.
Clipping (photography): The loss of highlight or shadow detail when image values exceed a sensor or encoding limit. Separate exposures preserve details that would clip in a single capture.
High dynamic range imaging: Imaging methods that represent scene brightness ranges broader than conventional display or capture formats. Multi-exposure capture is one acquisition method within this broader imaging field.
Landscape photography: Photography of natural environments, from broad vistas to intimate outdoor scenes. Bright skies and shaded foregrounds commonly motivate bracketed HDR capture.
Image registration: The alignment of corresponding features across two or more images. Alignment limits doubled edges when the camera or scene shifts between exposures.
RAW image format: A minimally processed recording of sensor data that retains substantial tonal and color information. RAW files can preserve more usable highlight and shadow information for merging.
