What does two-stop dynamic range mean?

In photography, dynamic range usually refers to the difference between the highest and lowest brightness in a photo. That is, dynamic range refers to the degree of difference between the brightest and darkest parts of a photo. Some cameras produce photos with a small dynamic range, while other cameras have a larger dynamic range and can better restore the details of the scene.

Two-stop dynamic range refers to the automatic exposure (AEB) function used when taking photos, which divides the camera exposure into three parts: normal exposure, overexposure and underexposure. Among them, the two stops of dynamic range are the results of shooting with only two stops of normal exposure and underexposure. This way the shooting can ensure more details and is more convenient during post-processing.

Two-stop dynamic range is widely used in landscape photography and architectural photography. Because the brightness difference in these scenes is relatively large, using dual-stop dynamic range when shooting can better restore scene details and increase the sense of layering and space in the picture. In addition, the two-stop dynamic range can also make the picture softer and more natural, making it more comfortable for the eyes. Therefore, mastering the use of two levels of dynamic range can make your photos more outstanding.
