Test method: How we measure dynamic range

| One of the most important parameters in a digital camera is its dynamic range. Dynamic range in photography describes the ratio between the maximum and minimum measurable light intensities (white and black, respectively). Once your subject exceeds the camera's dynamic range, the highlights wash out to solid white, and the darks become solid black. Cameras with a large dynamic range are able to capture shadow detail and highlight detail at the same time. Cameras with a small dynamic range provide you with blown-out highlights and shadows. |  |

Both Printer and Photo paper define the scoreFor our printer reviews we start by printing two test files: color and grayscale (including 'pure' white and black). |

Resolution, noise and autofocus. We measure these important camera features according to the same strict protocol for each camera. We combine the measurements into graphs and tables, which you can use to compare the image quality of cameras. Initially, these numbers and graphs might be overwhelming. And you may wonder how those numbers can help you choose a good camera. |
