Step 7 | Camera Angles and Techniques
The camera is an amazing tool. In 3D, unlike the real world, physical limitations don’t exist. You can create a scene where the camera takes you on a journey inside the blood vessels of a human body, or to be an eye-in-the-sky in your scenes, it can be used to create impossible perspectives, to zoom and pan and so much more.
First, it’s useful to look at some of the differences between 3D cameras and real life cameras. In 3D, unlike in real life, there is no need for a lens, focusing controls, film, aperture, etc. All of these functions are controlled via software. Where things are similar is how the camera is used. In 3D, you can create one or more cameras, position them exactly as desired in 3D space and use settings to mimic focal length, depth of field, etc. Other options for moving a 3D camera are similar to those in movie making, including truck, dolly, motion blur, orbit and pan.
In addition, software cameras have no size or weight restrictions. You can move a camera to any location and even inside the tiniest objects. You can also animate cameras so that several operations take place at once, such as a zooming into a scene while changing the depth of field. Once you create a camera in 3D, you can pick a view and assign the view in that view to the camera, meaning that you will see the scene from the perspective of the camera.
