MutableCam has three modes.SCANMODE: progressive image captureFLUIDMODE: scanmode with modulationGHOSTMODE: filters out moving objectsScanmode and fluidmode are fairly intuitive. Just press start and watch them go. Ghostmode is for long-exposure shots, so keep the phone steady (not with your hands). Ideally, it will capture everything that stays still (like buildings), and nothing that’s moving (like people).
