The manual exposure mode of the camera is the state of the camera when shooting.

The manual exposure mode of the camera allows the user to manually adjust the aperture and shutter speed when shooting.

Manual exposure mode is a shooting mode of the camera, which allows the photographer to completely control the exposure parameters. In manual mode, users can manually adjust the aperture size and shutter speed to achieve the required exposure level. Adjusting the aperture affects the amount of light entering the lens, while adjusting the shutter speed controls the exposure time of the photosensitive element (such as film or sensor). Manual exposure mode is suitable for occasions that need more accurate exposure control, such as special lighting conditions or artistic creation needs.
