Rotate camera around object/ and then return to it's origin

Don’t have a setup for this; wanted to try making the camera move around like how you normally would a character.
However once you let go of the button or when you stop moving the camera it immediately returns back to it’s fixed rotation.

Any ideas on what nodes to start with for this?

you could attach your camera to a spring arm, then rotate the spring arm using linear interpretation aka “lerp”, Here is a tutorial on using lerp. He uses it to move a block, but you could do the same thing with rotation
