This is essential to know when you have a scene where you want to either final render from multiple angles or even simply test render from multiple angles. This first method to switch active cameras in Blender is by going to the scene settings tab(a picture of a cone and a sphere). Here you will find a “Camera” menu at the top - If click on the input area it will come up with a list of all the cameras in your scene. Simply select the camera you want to render from and it will become your active/renderable camera once selected. The second method to change your active camera is by selecting a none active camera and then using the cntrl + ‘0’ shortcut. This will then make the camera you had selected your current active camera.
