How to use the camera in AE

In After Effects, cameras can be used to create three-dimensional space scenes and add depth and dynamic effects to two-dimensional images. Here are some basic steps to use the camera:

To create a camera layer: select the Layer menu in AE, and then select New >; Camera creates a camera layer. In the "New Camera" dialog box that pops up, you can select the camera type and set parameters, such as focal length and depth of field.

Set the scene: place the layer in three-dimensional space and adjust the camera position and angle so that you can see different angles and perspectives of the scene.

Animated camera: Use keyframe animation in the camera layer to make the camera move, rotate and scale in the scene. You can also control the speed and dynamic effect of camera movement by adjusting the curve editor.

Simulation of lens effect: special plug-ins can be used in the camera layer to simulate various camera lens effects, such as fisheye, wide angle and telephoto.

Depth composition: When two or more layers are combined, you can use a camera to create a true sense of depth. By adjusting the position, scaling and rotation of the layer, as well as the camera's viewing angle and focal length, you can place the layer on different depth planes, thus creating realistic 3D effects.

In a word, the camera is a very useful tool in AE, which can help you create realistic 3D scenes and add depth and dynamic effects.
