Getting the perfect image from an AI model can sometimes feel like a game of chance. You know what you want, but the AI doesn't always seem to understand. The secret to bridging that gap isn't just about *what* you ask for, but *how* you ask for it.
This guide provides a set of best practices for prompt engineering, focusing on techniques that will help you gain more control and create higher-quality images with any AI image generator.
The Core Principle: Describe the Scene
The most important shift to make is moving from a list of keywords to a descriptive narrative. An AI model's strength is its deep understanding of language. A paragraph that describes a scene will almost always produce a better, more coherent image than a list of disconnected words.
Instead of: `cat, wizard hat, fantasy, cute`
Think more like: `A photorealistic picture of a fluffy ginger cat sitting on a wooden floor. It's wearing a small, knitted wizard hat that looks like it's sitting comfortably on its head. The scene is lit by soft, natural light from a window.`
This narrative approach gives the AI context, helping it understand the relationships between objects, the environment, and the desired mood.
1. Crafting Photorealistic Scenes
For realistic images, think like a photographer. Mentioning camera angles, lens types, lighting, and fine details guides the model toward a photorealistic result.
- Subject & Action: Clearly describe your main subject and what they are doing. (e.g., "an elderly ceramicist carefully inspecting a tea bowl")
- Environment: Set the scene. (e.g., "in his rustic, sun-drenched workshop")
- Lighting: Lighting is crucial for mood. (e.g., "illuminated by soft, golden hour light streaming through a window")
- Camera Details: Specify the shot type or lens for more control. (e.g., "A close-up portrait," "Captured with an 85mm portrait lens, creating a soft, blurred background (bokeh)")
Example Prompt:
> A photorealistic close-up portrait of an elderly Japanese ceramicist with deep, sun-etched wrinkles and a warm, knowing smile. He is carefully inspecting a freshly glazed tea bowl in his rustic, sun-drenched workshop. The scene is illuminated by soft, golden hour light streaming through a window, highlighting the fine texture of the clay. Captured with an 85mm portrait lens, resulting in a soft, blurred background.
2. Designing Stylized Illustrations & Stickers
When creating assets like stickers or icons, be explicit about the style and background.
- Style: Name the style directly. (e.g., "A kawaii-style sticker," "A flat-design icon")
- Subject: Describe the character or object. (e.g., "a happy red panda wearing a tiny bamboo hat")
- Design Elements: Specify the line style, shading, and color palette. (e.g., "features bold, clean outlines, simple cel-shading, and a vibrant color palette")
- Background: For assets, explicitly request a transparent or white background. (e.g., "The background must be white.")
Example Prompt:
> A kawaii-style sticker of a happy red panda wearing a tiny bamboo hat, munching on a green bamboo leaf. The design features bold, clean outlines, simple cel-shading, and a vibrant color palette. The background must be white.
3. Generating Accurate Text in Images
To render text accurately, be clear about the text itself, the font style, and the overall design.
- Text: Put the exact text you want in quotes. (e.g., "for a coffee shop called 'The Daily Grind'")
- Font Style: Describe the font you envision. (e.g., "in a clean, bold, sans-serif font")
- Design: Explain the overall style and any accompanying icons. (e.g., "A modern, minimalist logo... featuring a simple, stylized icon of a coffee bean")
- Color Scheme: Specify the colors. (e.g., "The color scheme is black and white.")
Example Prompt:
> A modern, minimalist logo for a coffee shop called 'The Daily Grind'. The text should be in a clean, bold, sans-serif font. The design features a simple, stylized icon of a coffee bean seamlessly integrated with the text. The color scheme is black and white.
4. Creating Professional Product Mockups
For clean, professional product shots, think like a commercial photographer.
- Product: Describe the product in detail. (e.g., "a minimalist ceramic coffee mug in matte black")
- Setting: Specify the surface or background. (e.g., "presented on a polished concrete surface")
- Lighting: Describe the lighting setup and its purpose. (e.g., "a three-point softbox setup designed to create soft, diffused highlights and eliminate harsh shadows")
- Camera Angle: Explain the angle to showcase specific features. (e.g., "a slightly elevated 45-degree shot to showcase its clean lines")
Example Prompt:
> A high-resolution, studio-lit product photograph of a minimalist ceramic coffee mug in matte black, presented on a polished concrete surface. The lighting is a three-point softbox setup designed to create soft, diffused highlights. The camera angle is a slightly elevated 45-degree shot to showcase its clean lines. Ultra-realistic, with sharp focus on the steam rising from the coffee.

A Final Thought: How to Write Better Prompts?
The tips above are a great starting point. But as you tackle more complex tasks, you might find yourself wondering: why do my prompts still produce inconsistent results? How can I structure my ideas better?
This is a common challenge. You might be facing issues like:
- 🤔 Lack of Clarity: Your prompt is too vague for the AI to interpret correctly.
- 📝 No Structure: Your ideas are written down without following best practices for prompting.
- 🎨 Complex Tasks: You're trying to generate a detailed image that requires more advanced prompt engineering knowledge.
- ⏱️ Wasted Time: You're spending too much time tweaking and re-running prompts with little improvement.
Before you spend another hour debugging your prompt, I suggest taking a moment to use a tool I've been working on called Dativus.
It’s a free, lightweight tool that helps you optimize your prompts based on proven engineering best practices. It can automatically convert a simple idea into a structured prompt template, with special support for image and video generation tasks.
Most importantly, it's privacy-first. It uses a "Bring Your Own Key" (BYOK) model, meaning your API key and prompts are processed directly in your browser and never sent to a server.
It’s completely free, requires no registration, and all data stays on your machine. It might just be the helper you need to get the most out of your AI tools. You can check it out here: https://dativus.tech
