ae摄像机介绍（AE camera introduction） In After Effects, we often need to use one or more cameras to create the space scene, watch the synthesis of space optical characteristics of camera tool can not only simulate the real camera, more can go beyond constraints in three real camera tripod, gravity and other conditions, and move freely in space. Now lets introduce the creation and setup of the camera. Select the menu Layer - New - Camera, or press the shortcut key Ctrl+Shift+Alt+C to open a camera parameter settings dialog box. Name: name the camera Preset: camera preset, in this drop-down menu provides 9 common camera lens, including the standard 35mm lens, 15mm wide-angle lens, 200mm telephoto lens, as well as custom lenses. The 35mm standard lens has a visual angle similar to that of the human eye. 15mm wide-angle lenses have a wide range of vision, similar to the eagle eye observation space, because of the vast range of vision to see a wide space, but it will produce a space perspective deformation. 20mm long lenses can pull objects in the distance and reduce the range of vision. Only minor space can be observed, but almost no deformation occurs. Units: through this drop-down box, select the parameter units, including: pixel (pixel), inches (inch), millineters (mm) three options. Measure Film Size: can change the Film Size (film size) benchmark direction, including: Horizontally (horizontal) direction, Vertically (vertical) direction and Diagonally (diagonal) direction three options. The larger the value of Zoom:Zoom, the larger the layer size displayed by the camera and the smaller the field of view. Angle of View: view position. The larger the angle, the wider the field of view, the smaller the angle and narrower the view angle. Film Size: film size. Refers to the actual size of the image seen through the lens. The larger the value, the larger the field of view, the smaller the value and the smaller the field of view. Focal Length: focus setting refers to the distanc
