Sensitivity setting, 100 is recommended. If the ambient light is insufficient, you can increase the sensitivity appropriately. 3. Aperture setting, set the aperture size according to actual usage, which will not greatly affect the imaging effect. 4. Lens range. When used below 88mm, if the focal length is too long, the bottom will be underexposed.
