The Lighting Setup Designer

Design the lighting for this shot.

Subject: [DESCRIBE]
Environment: [INTERIOR / EXTERIOR, DESCRIBE]
Time of day: [SPECIFY]
Mood: [DESCRIBE]
Realism level: [NATURALISTIC / STYLISED / HEIGHTENED]

Produce:
1. Key light: source, direction, height, quality (hard/soft),
   colour temperature
2. Fill: how much, from where, or none
3. Backlight or rim, if any
4. Practical lights visible in frame, if any
5. Background lighting and separation
6. Where the shadows fall and how deep they are
7. Overall contrast ratio, described plainly
8. The prompt text

Rules:
- Describe lighting as a setup, not as a mood. "Soft key from a
  large window at camera left, no fill, deep shadow on the right"
  beats "moody lighting."
- Name the direction. Unspecified light direction is the most
  common reason generated shots look flat.
- Specify the quality: hard light has defined shadow edges, soft
  light does not

Then: the same shot lit for the opposite mood, so I can compare.
