Dynamic range is measured in steps of exposure (EV). Each step corresponds to a doubling of the amount of light. So, for example, if a certain camera has a dynamic range of 8 EV, this means that the maximum possible value of the useful signal of its matrix refers to the minimum as 28: 1, which means that the camera is capable of capturing objects within one frame that differ in brightness not more than 256 times. More precisely, it can Continue reading
