Title: Basic Elements in Photography
Article: Photography is a technique that blends science and art, involving many basic elements. Focal length refers to the field of view that a camera lens can capture, with wide-angle and telephoto lenses suitable for different scenes. Aperture controls the opening and closing size of the camera lens, affecting the depth of field. Shutter speed is an essential factor in controlling the exposure time of the camera, determining the clarity of the photo. White balance adjusts the camera's photosensitive component to meet different lighting conditions, ensuring the accuracy of the photo's color temperature.
