🤖 [The Complete AI Toolkit Series] Part 8
The prompt formula for AI image generation, with real-world use cases.
For anyone with a clear image in their head but zero drawing skill, AI image generation is a genuine game-changer. The catch: a lazy prompt gets you something wildly different from what you pictured. Here’s the formula for prompts that actually deliver, backed by real examples.
1. The Anatomy of a Good Image Prompt
💡 The Image Prompt Formula
① Subject — what’s actually in the image (person, object, scene)
② Style — photorealistic, illustration, watercolor, 3D render, etc.
③ Composition/Angle — close-up, wide shot, bird’s-eye view, etc.
④ Lighting/Mood — warm lighting, moody and dark, natural daylight, etc.
⑤ Detail — color palette, texture, background elements
2. Real-World Case: Creating a Blog Thumbnail
📌 Real Scenario: A Travel Blogger’s Thumbnail Problem
A travel blogger needed a thumbnail for a post about “winter travel in Jeju Island” but was struggling to find a copyright-free stock photo that matched the mood. Using the prompt “Jeju Island winter coastline, waves crashing on black basalt rocks, overcast sky, warm-toned photography style, wide angle,” they generated exactly the atmosphere they had in mind — without any licensing worries.
3. Real-World Case: Creating a Concept Graphic for a Pitch Deck
📌 Real Scenario: A Startup Founder’s Investor Presentation
A startup founder needed a visual to represent “growth trajectory” for an investor pitch deck. With the prompt “minimalist infographic style, rocket icon above an ascending graph, pastel background, clean flat design,” they got a presentation-ready concept graphic instantly — no designer required for a last-minute deck revision.
4. Prompt Examples You Can Adapt
🖼️ Blog/Social Media Image
“Warm afternoon sunlight streaming through a cafe window, coffee cup and laptop, photorealistic style, natural light, cozy atmosphere”
🖼️ Logo/Brand Reference Image
“Minimalist logo design, leaf shape, green and white color combination, flat vector style”
🖼️ Presentation Concept Illustration
“Illustration symbolizing teamwork, multiple people holding hands together, pastel tones, simple flat design”
5. Fixing Results That Miss the Mark
| Problem | Fix |
|---|
| Style doesn’t match what you wanted | Be more specific with style keywords: “photorealistic,” “in an illustrated style,” etc. |
| Composition looks off | Explicitly state the angle: “wide shot,” “close-up,” “front-facing” |
| Colors aren’t right | Specify a precise color palette or tone (pastel, vivid, etc.) |
| Text renders oddly in the image | Image generators often struggle with text rendering — add text separately with editing software instead |
6. Copyright Considerations You Should Know
⚠️ Things to Watch for With AI-Generated Images
✔ Commercial usage rights and licensing terms vary between services — always check the terms of service before commercial use
✔ Prompts attempting to recreate specific real people or well-known copyrighted characters can raise copyright and publicity rights issues
✔ For anything used as a brand logo or important commercial asset, separately verify there’s no trademark conflict
7. A Practical Workflow to Follow
✅ An Efficient Process for Getting the Image You Want
1️⃣ Build your prompt using the five elements: subject, style, composition, lighting, detail
2️⃣ Generate multiple options and pick your favorite
3️⃣ Identify what’s off and refine the prompt, then regenerate
4️⃣ Check the service’s licensing terms before using the final image
