Optical Rack Focus Test Prompt

A high-tension optical rack focus with hard-flash illumination. The frame starts with shallow focus locked squarely on the sculptural kiss-curl and sharp eyeliner of the female model in the foreground. On beat, the focus violently racks to the background wall, bringing the razor-sharp edge of the elongated silhouette shadow and the male model's direct stare into crisp focus, throwing the foreground into painterly softness.
