Step-by-step explanation:
In the context of photography, the primary differences between a manual and a normal automatic start are related to shooting modes. In manual mode, the photographer has full control over the settings such as shutter speed and aperture value. This requires experience and allows for more creative control. On the other hand, in normal automatic mode, the camera determines the optimal settings based on the scene and lighting conditions. This mode is recommended for beginners or when quick adjustments are needed.
