How do I prompt for different lighting in an image?
Key lighting terms to use
Lighting sets the mood and realism of an image. To get specific lighting, use descriptive phrases that cover direction (e.g., 'backlit', 'side-lit'), quality (e.g., 'soft', 'harsh'), and color (e.g., 'warm', 'cool'). Common terms include 'golden hour', 'blue hour', 'overcast', 'studio lighting', 'neon lights', and 'candlelight'.
You can also reference lighting styles from photography or cinema, like 'Rembrandt lighting', 'butterfly lighting', or 'film noir'. These terms carry specific connotations that models often recognize. For example, 'Rembrandt lighting' implies a single light source at a 45-degree angle, creating a triangle of light on the cheek.
- Time of day: golden hour, blue hour, midday sun, twilight
- Direction: front-lit, backlit, side-lit, top-down, underlighting
- Quality: soft, hard, diffused, direct, dappled
- Color: warm, cool, tungsten, fluorescent, neon
- Style: cinematic, studio, natural, dramatic, moody
Combining lighting with other elements
Lighting interacts with subject, environment, and mood. To get a cohesive image, integrate lighting into your overall scene description. For example, 'a portrait of a woman in a dimly lit room, lit by a single candle, warm glow on her face, deep shadows in the background'.
If the lighting isn't coming through, try adding more specific details or using synonyms. Sometimes models respond better to 'illuminated by' or 'light source from'. Experiment with placement: lighting terms early in the prompt may carry more weight.
- Pair lighting with mood: 'soft light, peaceful atmosphere'
- Specify light source: 'lit by a window', 'neon signs'
- Use lighting to define time: 'sunset backlight'
- Adjust intensity: 'bright', 'dim', 'harsh', 'gentle'
Common mistakes
- Using vague terms like 'good lighting' that don't give the model specific direction.
- Forgetting to mention light direction, which can lead to flat or inconsistent illumination.
- Overloading the prompt with conflicting lighting terms, like 'harsh shadows' and 'soft diffused light'.
