There are many ways to move the camera, and each can create different emotional effects. Panning, for example, rotates horizontally, usually on a tripod, to follow or show something across the frame. This can create a sense of exploration, curiosity, or anticipation, as well as show the scale or context of the scene. Tilting rotates vertically and can evoke feelings of awe, wonder, or surprise, as well as show the height or depth of the scene. Zooming changes its focal length to make something appear closer or farther away and can create a sense of intimacy, importance, or shock. Dolly moves physically closer or farther away from the subject and can evoke feelings of motion, direction, or change. Tracking moves along with the subject and can create a sense of continuity, connection, or action. Finally, crane moves up or down from the subject and can evoke feelings of elevation, expansion, or transition.
