1Describe both planes
Models rarely know the lens name, so describe the result: two subjects at very different distances, both sharp, with a soft blurred seam between them. Keep the camera static.
Split-diopter style composition: {{foreground_subject}} in extreme close-up on the {{foreground_side}} side of frame, and {{background_subject}} far in the background on the other side. Both are in sharp focus at the same time, separated by a soft vertical band of blur through the middle of the frame. Action: {{action}}. Setting: {{setting}}. Camera: static, locked-off, eye level. Lighting: {{lighting}}. Style: 1970s thriller look, warm tungsten tones, film grain. Mood: {{mood}}. Duration {{duration}}, aspect ratio 2.39:1 letterboxed inside 16:9. Avoid: text, captions, watermarks, logos, extra limbs or fingers, warped faces, flicker, sudden cuts, one of the two subjects blurred, camera movement.2Fallback: composite it
If the model keeps blurring one plane, generate the foreground and background as two separate static shots and blend them with a soft vertical mask in your editor. It's what the real lens does optically.
Example input
Detective's face close on the left, a figure under a streetlight far right, rainy street at night, paranoid; 5s.
Example output
Split-diopter style composition: a detective's tired face, half-lit in extreme close-up on the left side of frame, and a figure in a long coat standing under a streetlight far in the background on the other side. Both are in sharp focus at the same time, separated by a soft vertical band of blur through the middle of the frame. Action: the detective's eyes slowly shift toward the figure, who doesn't move. Setting: a rain-soaked city street at night seen through a car window. Camera: static, locked-off, eye level. Lighting: sodium streetlight orange, dashboard glow on the face. Style: 1970s thriller look, warm tungsten tones, film grain. Mood: paranoid, watchful. Duration 5 seconds, aspect ratio 2.39:1 letterboxed inside 16:9. Avoid: text, captions, watermarks, logos, extra limbs or fingers, warped faces, flicker, sudden cuts, one of the two subjects blurred, camera movement.
Troubleshooting
- Background figure is blurred: add 'deep focus, everything sharp' and remove 'shallow depth of field' from any style preset.
- Letterbox bars are ignored: add them in the editor instead; it is more reliable.
Known limitations
- This is an unusual optical effect; most models approximate it with deep focus rather than a true split, so the compositing fallback is often needed.
