Moving Beyond Simple Prompts
Typing "a beautiful landscape" gets you a mediocre result. The difference between generic AI images and impressive ones comes down to prompt structure and parameter knowledge. This guide covers the complete toolkit for crafting effective image prompts across Midjourney, DALL-E 3, and Firefly.
The Universal Prompt Structure
Every good AI image prompt follows this structure, regardless of the tool:
[Subject] + [Action/Setting] + [Environment] + [Lighting] + [Style] + [Composition] + [Technical specs]Example applied to Midjourney:
/imagine prompt:
A lone wolf standing on a rocky outcrop at twilight
misty pine forest in the background
dramatic side-lighting casting long shadows
cinematic, photorealistic, National Geographic style
low angle shot, rule of thirds
--ar 16:9 --v 6 --stylize 300Each component serves a specific purpose and omitting any of them leaves the AI to make its own (often mediocre) choices.
Subject Descriptors
Be specific about your subject:
Weak: "a person"
Strong: "a woman in her 60s with gray hair and reading glasses, wearing a cable-knit cream sweater, holding a ceramic coffee mug, warm smile, crow's feet visible"
The AI has no concept of "interesting" — it generates exactly what you describe. Specific descriptors produce specific results.
Style Modifiers (Cross-Tool)
| Style | Midjourney Parameter | DALL-E/Firefly Approach |
|---|---|---|
| Photorealistic | --stylize 100 + "photorealistic" | "photorealistic, 8K, DSLR, f/2.8" |
| Oil painting | --stylize 600 + "oil on canvas" | "oil painting, impasto technique" |
| Anime/Manga | --niji 6 (separate model) | "anime style, Studio Ghibli influence" |
| 3D render | --stylize 400 + "octane render" | "3D render, Blender, Cycles" |
| Watercolor | --stylize 700 + "watercolor" | "watercolor painting, loose style" |
| Line art | --stylize 50 + "line drawing" | "black and white line art" |
Lighting and Atmosphere
Lighting transforms a flat image into a compelling one. Include one of these in every prompt:
- Golden hour: Warm sunset/sunrise light
- Cinematic lighting: Dramatic shadows, rim lights
- Studio softbox: Even, professional product lighting
- Neon/noir: Colored artificial light, dark atmosphere
- Backlit: Light source behind the subject
- Volumetric: Visible light beams (god rays)
Composition and Camera Terms
Adding photographic terms dramatically improves results:
- Shot type: "close-up," "wide shot," "aerial view," "extreme close-up," "macro"
- Lens: "35mm," "85mm portrait lens," "fisheye," "tilt-shift"
- Angle: "low angle," "bird's eye view," "Dutch angle"
- Framing: "rule of thirds," "symmetrical," "leading lines"
Midjourney-Specific Parameters Deep Dive
| Parameter | Range | Effect at High Values |
|---|---|---|
--stylize | 0-1000 | High = more artistic interpretation, less literal |
--chaos | 0-100 | High = more diverse, unpredictable results |
--weird | 0-3000 | High = surreal, strange compositions |
--iw | 0-3 | Weight of reference image vs text prompt |
--no | text | Negative prompt: exclude specific elements |
Example with advanced parameters:
/imagine prompt: futuristic cyberpunk city street at night, neon reflections
in wet pavement, flying cars in distance --ar 21:9 --chaos 30
--stylize 600 --no people, garbage, graffiti --v 6FAQ
Q: Does DALL-E 3 support negative prompts?
Not directly. DALL-E 3 does not have a --no parameter like Midjourney. Instead, you include what you do NOT want in the prompt: "A modern kitchen with NO island, NO stainless steel appliances." This works but is less reliable than Midjourney's dedicated negative prompt.
Q: What is "seed" and should I use it?
A seed is a number that determines the random starting point for image generation. Using the same seed + same prompt produces the same image. Useful when you find a composition you like and want to tweak the prompt while keeping the general layout. In Midjourney, add --seed 12345. In DALL-E, seeds are not exposed to users.
Q: How do I iterate on a specific image?
Midjourney: Use the V buttons to create variations, then U to upscale the best one. Use modified prompts with --seed. DALL-E 3: Ask ChatGPT to "generate 4 variations of this image" or upload or upload previously generated images and ask for edits based on the existing composition.
Frequently Asked Questions
Q: What is the most important thing to include in an AI image prompt?
The subject and its environment. A weak prompt like a cat gives AI too much freedom. A strong prompt specifies: subject, action, environment, lighting, and style. Specificity produces predictable results.
Q: What are negative prompts and how do I use them?
Negative prompts tell AI what NOT to include: ugly, deformed, blurry, extra limbs, watermark. Stable Diffusion and Midjourney support negative prompting. This significantly improves quality by steering AI away from common failures.
Q: How long should an AI image prompt be for best results?
20-50 words works best. Under 10 words gives AI too much freedom. Over 100 words can confuse it. Use: subject + action + environment + lighting + style + technical parameters.
