 In this instance, the false diorama effect was achieved digitally using helicopter footage of full-size vernal and urban landscapes that was broken down into separate planes.It involves hand creating as many as eight planes of z-buffering over live-action footage, one frame at a time, resulting in an animated black and white matte (filmmaking) sequence.These mattes are then blended together with varying degrees of blur to create the effect of shallow depth of field.
