You can enter the camera mode through the map, by clicking on the animatronic / remnant clot icon (or an unknown object icon if it does not turn out to be a ball with rewards), by clicking on the “Fight” button in the window with a description of the animatronic (if you do not want to, you can secure yourself with a jammer for 25 Phase-coins, or try your luck and wait), or by clicking on the “Collect” button in the remainder collection window.
