Complete Guide to AI Image Prompt Engineering: Universal Tips for Midjourney, DALL-E 3, and Stable Diffusion

Master the art of designing image prompts that work across tools

"Why does the same prompt produce great images for others but terrible ones for me?"

The answer is usually not the tool, but the quality of the prompt. Image prompts follow a learnable methodology—once you master it, you can generate great images with any AI image tool.

1. The Four Core Dimensions of Image Prompts

1.1 Subject

Describe the core content of the image:

❌ Weak subject description: a woman ✅ Strong subject description: a 25-year-old Chinese woman in a traditional qipao, confident expression, standing posture

A subject description should include: age/features + clothing/state + action/pose

1.2 Context

Describe the environment surrounding the subject:

❌ Weak context description: in a city ✅ Strong context description: on a bustling Shanghai street at night, neon signs reflecting on wet pavement, shallow depth of field

A context description should include: location features + time/weather + spatial relationships

1.3 Lighting

Lighting is key to making images look professional and is often overlooked:

Common lighting terms:

golden hour — warm yellow light just after sunrise or before sunset

soft diffused light — soft scattered light (overcast/indoor)

dramatic rim lighting — dramatic edge lighting

studio lighting — professional studio lighting

volumetric light — light beams in fog

neon glow — neon light

candlelight — warm, intimate candle light

1.4 Style

Define the overall visual style:

Photography styles:

photorealistic, shot on Sony A7III — realistic photography

35mm film photograph — film grain texture

product photography — commercial product photography

Illustration styles:

digital illustration, flat design — flat illustration

oil painting, impressionist — oil painting, impressionist

watercolor, loose brushstrokes — watercolor

anime style, Studio Ghibli — Studio Ghibli anime style

3D styles:

3D render, octane render, soft shadows — 3D rendering

isometric view — isometric view (common for app illustrations)

2. Platform Differences and Adaptation

Midjourney

Strengths: automatic beautification, stable output

Tips: concise description + style words, no need for negative prompts

Example: portrait of an elegant elderly Japanese man, traditional clothing, contemplative, soft morning light, photorealistic

DALL-E 3 (ChatGPT / API)

Strengths: understands natural language, supports Chinese

Tips: use full sentences to describe the scene; it understands context

Example:

Generate an image: a modern coffee shop interior, warm yellow lighting, young people working on laptops, rainy city street view outside, photography style

Stable Diffusion

Strengths: local and free, highly controllable

Tips: keyword list + negative prompts

Example:

elegant Japanese elderly man, traditional kimono, soft morning light, photorealistic, ultra detailed, 8k | ugly, blurry, deformed

3. High-Frequency Use Case Templates

4. Common Failure Causes and Fixes

ProblemCauseSolution

Blurry/low quality imageNo quality words specifiedAdd "high quality, ultra detailed, sharp focus" Deformed handsHand generation is AI's weak pointAdd "perfect hands" or use inpainting to fix Too "AI-like" styleStyle words too genericReference specific artist or photographer styles Background too complexNo background controlAdd "clean background" or "simple background" Text generation errorsAI cannot reliably generate textDo not request text in prompts Multiple subjects in wrong positionsNo spatial relationship describedClearly specify each person's position and relationship

5. Advanced: Use AI to Generate Prompts

You can ask ChatGPT or Claude to optimize your prompts:
