Cameras in Unity

Camera Basics

Adding a camera to a scene in Unity is easy, but there's more to it than that. It's critical to spend time fine tuning the camera angles, the camera movement, and the final rendered image, because that's how your players will see the game. 5 steps

Image Effects

In Unity, an image effect is a script that's applied to a camera that modifies the rendered image. Image effects are similar to an Instagram filter or a Photoshop effect, in that they take an image and make adjustments. Image effects can dramatically change the look of any game. 5 steps

• Extra Credit Try creating your own combination of image effects to change the mood of the scene. Using color correction, you might want to try a high-contrast black-and-white film noir look, or a monochromatic color palette where only different shades of the same color are used.

Camera Movement

When a camera remains completely still, it can draw attention to the artificial nature of the scene. Adding some subtle movement helps to draw players into an experience. 8 steps

Camera Switching

Switching between two cameras in Unity is simple. The difficult part is determining when the switch should occur. In these lessons, you'll learn how to write a Camera Manager script to schedule and coordinate multiple cameras in a scene. 8 steps

• Extra Credit Up for a serious challenge? Try creating a camera that fades between two angles without fading to a color between. You'll likely need to render two angles simultaneously, which means that one of the cameras will have to be passed to a full-screen render texture.
