Examples
First-person view from a soldier jumping from a transport plane — the camera shakes with turbulence, oxygen mask reflections flicker — as the clouds part, the battlefield below pulses with anti-air fire and missile trails.
Rear tracking shot of a sleek black cat sprinting through a bustling Indian street market at dusk, the air thick with spice aromas and voices shouting in Hindi. The cat dashes past crowds and carts, then springs onto a stack of woven baskets, bouncing onto the vibrant.
A child gasps and steps back with wide eyes after opening a glowing chest, mouth slightly open, stunned and speechless, slow dolly-in, low-angle shot, magical golden light filling the attic.
