Scene modes are preset settings on cameras that help users capture images in specific situations or environments. These modes adjust various camera settings, such as exposure, focus, and white balance, to optimize the photo quality for particular scenes. Common scene modes include portrait, landscape, night, and sports, each designed to enhance the final image based on the subject and lighting conditions. Using scene modes is beneficial for both beginners and experienced photographers, as they simplify the process of taking great photos without needing extensive knowledge of camera settings. By selecting the appropriate mode, users can quickly adapt to changing environments and achieve better results with minimal effort.
