What is the difference between the standard of dynamic range optimization in SLR cameras and advanced ones?

Usually, dynamic optimization is set as standard, and it is set as advanced only for scenes with dark parts and bright parts.

Other knowledge related to the dynamic range of SLR cameras:

1, dynamic range, refers to the gray transition from white to black in the shot picture, commonly known as tolerance, which reflects the tolerance of the picture from white to black;

2. In the real environment with large light ratio (such as the cave scene in the sun), the tolerance of the camera can't correctly reflect this scene with large light ratio, so the dynamic range optimization is set, and some cameras are abbreviated as HDR；; ;

3. The principle of dynamic range optimization is that the camera automatically reduces the brightness of the bright part, improves the brightness of the dark part, and prevents black light and white light. Its purpose is to make the highlights in a photo not exposed, and the details of the dark parts can be preserved, which is HDR technology;

4. Dynamic optimization is inversely proportional to contrast. The higher the dynamic optimization setting, the lower the picture contrast.

5. The larger the dynamic range of a digital camera, the richer the dark details and bright details that can be recorded at the same time. Note that the dynamic range is different from the tonal range.
