How do I reset the player's camera after i change the camera's CFrame and Subject?

lets say i have a part and a character, i want the part to be the subject for a time, but when a certain event is satisfied, i want the camera to follow the player again and not have that weird CFrame thing where you can't move the camera.

Do,

Event:Connect(function() game.Workspace.CurrentCamera.CameraType = Enum.CameraType.Custom end)
