Samples
Establishing shotCamera motion, scene coherence over time
PromptSlow aerial push in over a coastal cliff road at golden hour, waves breaking on rocks below, a single car travelling along the road. Smooth continuous camera movement, warm cinematic colour grade.
Close-upFluid motion, fine detail, temporal stability
PromptClose-up of a barista pouring steamed milk into an espresso, latte art forming in the crema, steam rising from the cup. Shallow depth of field, soft window light, subtle handheld movement.
