If your AI images look flat, muddy, or randomly lit, it is usually not your subject. It is the lighting language.
This cheat sheet gives you copy-paste camera + lighting blocks you can drop into any prompt to get consistent results, plus quick troubleshooting so you know what to tweak first.
The fastest way to write a strong prompt
Use this simple order. You can keep it short or expand it.
Prompt formula:
- Subject and scene
- Composition and camera
- Lighting setup
- Mood and color
- Quality and constraints
Copy block template:
Camera language that actually changes the image
If you only say cinematic, you get random. Add one or two camera details.
Shot and framing
Use one:
- close-up portrait, head and shoulders
- medium shot, waist-up
- wide shot, full body
- over-the-shoulder
- top-down flat lay
- three-quarter view
Lens and depth of field
Pick based on your goal:
- Portrait: 85mm lens, shallow depth of field, soft background bokeh
- Product: 50mm lens, f/8 look, sharp details, minimal blur
- Cinematic scene: 35mm lens, moderate depth of field, natural perspective
- Ultra dramatic: 24mm wide-angle, strong perspective, foreground emphasis
Focus and detail
Add one:
- sharp focus on eyes, soft background
- tack sharp product edges, crisp label text not required
- realistic skin texture, no plastic smoothing

Lighting cheat sheet: paste-ready blocks + examples
1) Softbox lighting
What it looks like:
- Soft, flattering light
- Gentle shadows
- Clean, modern studio vibe
Best for:
Headshots, product photos, thumbnails, brand visuals
Paste-ready lighting blocks:
Example prompt:
Quick fixes:
- Too flat: add more contrast, reduce fill, add a rim light
- Too harsh: add more diffusion, say softer wrap, move key higher
2) Rim light
What it looks like:
- A bright edge highlight on hair and shoulders
- Strong separation from the background
- Premium, cinematic polish
Best for:
Dark backgrounds, dramatic portraits, product silhouettes
Paste-ready lighting blocks:
Example prompt:
Quick fixes:
- Rim too thick: say thinner rim, reduce halo, tighten edge highlights
- Background gets bright: add controlled spill, use flags, darker background
3) Rembrandt lighting
What it looks like:
- Classic dramatic portrait lighting
- One side of the face brighter, the other side in shadow
- A small triangle of light on the shadow cheek
Best for:
Storytelling portraits, cinematic interviews, classic art vibes
Paste-ready lighting blocks:
Example prompt:
Quick fixes:
- Not dramatic enough: add deeper shadows, higher contrast, reduce fill
- Too harsh: add soft falloff, add slight diffusion, keep triangle highlight
4) Neon lighting
What it looks like:
- Colored light sources, glow, reflections
- Cyberpunk, nightlife, street portrait energy
Best for:
Music visuals, nightlife posters, edgy thumbnails, product neon scenes
Paste-ready lighting blocks:
Example prompt:
Quick fixes:
- Skin looks weird: add realistic skin tones, reduce saturation, specify softer bloom
- Too chaotic: limit to two neon colors, reduce clutter, simplify background
Troubleshooting: what to change first when lighting looks wrong
Problem: The image looks flat
Do this:
- Add contrast or low key lighting
- Reduce fill or say subtle fill
- Add rim light separation
Paste fix:
Problem: The image looks harsh
Do this:
- Add diffusion, soft wrap, gentle falloff
- Use softbox language
- Move key higher and slightly farther away in the prompt
Paste fix:
Problem: The image is muddy or gray
Do this:
- Specify cleaner highlights and deeper blacks
- Add color temperature or a simple grade
- Reduce atmospheric haze
Paste fix:
Problem: Light direction feels random
Do this:
- State the key direction clearly
- Add one secondary light only
Paste fix:
Camera + lighting combos for common creator assets

FAQ
What are the best lighting keywords for AI image prompts
The most reliable are softbox lighting, rim light, Rembrandt lighting, low key lighting, diffused light, and directional key light with a clear angle like 45 degrees.
How do I make lighting look more realistic in AI images
Specify a single key light direction, realistic skin texture, controlled highlights, and a camera setup like 35mm or 85mm with depth of field. Keep the scene simple and add one secondary light at most.
Why do my AI images look flat even with cinematic lighting in the prompt
Cinematic is vague. Add contrast, reduce fill, and include a rim light or low key lighting. Also specify where the key light is coming from.
How do I get Rembrandt lighting reliably
Use a single key light high and to the side, mention the triangle cheek highlight, and reduce fill so shadows stay deep.
How do I do neon lighting without ruining skin tones
Limit the neon palette to two colors, reduce saturation slightly, and explicitly request realistic skin tones and controlled bloom.
Should I include lens and depth of field in every prompt
Not always, but it helps when you want consistency. Portraits usually benefit from 85mm and shallow depth of field, while product shots benefit from sharper f/8 style detail.
Conclusion
Great prompts are not longer. They are more specific where it matters: camera, light direction, and contrast.
Save your favorite blocks, reuse them, and tweak one thing at a time. If you want to keep these looks organized and quickly compare outputs across models, try QuestStudio and build a small Prompt Library of your go-to lighting setups.
