Use Case

A Use Case is a real photographic scenario that describes the requirements for a camera or a lens to shoot a certain type of photograph. DxOMark defines six Use Cases for scoring lenses and camera sensors (five for lenses, four for sensors): Travel & Family, Portrait & Studio, Landscape & Architecture, Reportage , Sports & Wildlife, and a general purpose use case to report sensor overall performance.

Too low exposure, resulting in a dark photo.



Vignetting (or light shading) is a progressive attenuation of brightness of an image when going far from its center, meaning that the corners of a rectangular image tend to be dark. Read more about how vignetting is defined, measured and scored.


The fundamental quality characterizing a photon, equivalent to its energy. Differing visible wavelengths are perceived as different colors.
