What is the latitude and dynamic range of a digital SLR

Latitude is the camera's ability to record the brightest and darkest details and gradations. Photos taken in the same environment with the same shutter speed, ISO, and aperture will have rich highlights and dark details, and the higher the tolerance.

Dynamic range represents the brightest to darkest range of a photo. The larger the dynamic range, the higher the tolerance, and the two are directly proportional to each other. Light ratio is used to describe the contrast between light and dark in a shooting scene.
