4. AI Image Generation Prompt Writing Tips

Regardless of which tool you use, the ability to write good prompts determines the quality of your results. Here are the key principles and practical examples for writing effective prompts in AI image generation.

4.1 Basic Prompt Structure

An effective prompt is composed by combining the following four elements:

• Subject: What to draw - "A traditional Korean hanok village", "An astronaut drinking coffee"
• Style: What artistic style to use - "watercolor style", "cyberpunk illustration", "realistic photograph"
• Mood: What feeling to convey - "warm and cozy", "mysterious and dreamlike", "bright and vibrant"
• Technical Elements: Quality and composition specifications - "high resolution", "front close-up", "golden hour lighting", "shallow depth of field"

4.2 Multilingual vs English Prompt Differences

Most AI image generation tools perform best with English prompts. However, as of 2026, multilingual prompt support has improved significantly.

• English Prompt Recommended: Midjourney, Stable Diffusion, Leonardo AI - These tools have overwhelmingly more English training data, so even for the same content, English prompts produce more accurate results.
• Good Multilingual Support: DALL-E 3 (ChatGPT), Google ImageFX, Canva AI, Microsoft Designer - ChatGPT-based tools have excellent natural language processing capabilities and understand prompts in various languages well.
• Practical Tip: Mixing your native language for the core subject with English for style/technical terms yields the best results. Example: "Traditional market scene, watercolor style, warm lighting, high detail"

4.3 Five Practical Prompt Examples

Here are ready-to-use practical prompt examples you can copy and use right away:

1. Blog Thumbnail: A modern minimalist workspace with a laptop showing AI interface, soft natural lighting from a window, clean desk with a coffee cup, professional photography style, shallow depth of field, 16:9 aspect ratio
2. Social Media Marketing: Vibrant flat illustration of diverse people using smartphones, colorful gradient background in purple and blue, modern vector art style, cheerful mood, perfect for social media banner
3. Game Concept Art: Epic fantasy castle floating in the sky above clouds, surrounded by waterfalls and ancient trees, dramatic golden hour lighting, cinematic composition, highly detailed digital painting, 4K resolution
4. Product Mockup: Minimalist product photography of a skincare bottle on a marble surface, surrounded by fresh green leaves and water droplets, soft studio lighting, white background, commercial quality
5. Character Design: Cute Korean-style chibi character, female warrior with traditional hanbok-inspired armor, cherry blossom motifs, anime art style, full body view, clean lineart with soft pastel colors

4.4 How to Use Negative Prompts

Negative prompts are a feature that specifies elements you want to exclude from the image, primarily supported by Stable Diffusion and Leonardo AI. Effective use of negative prompts can significantly improve image quality.

• Basic Negative Prompt: blurry, low quality, deformed, ugly, bad anatomy, extra fingers, extra limbs, watermark, text, signature
• Additional for Portraits: distorted face, asymmetric eyes, unnatural skin, plastic look, bad hands, crossed eyes
• Additional for Landscapes/Architecture: distorted perspective, impossible architecture, floating objects, unnatural colors

5. Copyright and Legal Considerations

Here are the copyright and legal issues you must be aware of before using AI-generated images in actual work. Since the legal framework has not yet been fully established despite the rapid advancement of AI image generation technology, a cautious approach is necessary.

5.1 Current Copyright Status of AI-Generated Images

Copyright for AI-generated images varies by country:

• South Korea: Under current copyright law, a copyrightable work is defined as "a creative expression of human thoughts or emotions." Purely AI-generated images are unlikely to be eligible for copyright protection as human creativity is difficult to recognize. However, if a human has made significant creative contributions (prompt design, iterative modifications, post-processing, etc.), there is room for copyright recognition. In 2025, the Ministry of Culture, Sports and Tourism released guidelines on AI-generated works, but legally binding judgments have not yet been established.
• United States: The U.S. Copyright Office (USCO) maintains the position that copyright is not granted to AI-generated images themselves. However, copyright may be recognized for parts that humans have creatively arranged or modified. The Thaler v. Perlmutter (2023) ruling confirmed that "human authorship" is a prerequisite for copyright.
• Japan: Japan takes a relatively flexible stance on AI-generated works, with discussions progressing toward recognizing copyright when there is creative human involvement using AI as a tool.

5.2 Considerations for Commercial Use

• Check Each Tool's Terms of Service: Commercial use conditions vary by tool. Midjourney allows commercial use only for paid subscribers, while Adobe Firefly allows commercial use even for free users. Always check the latest terms of service before use.
• Litigation Risk Related to AI Training Data: Some AI image generation models face ongoing lawsuits regarding the use of copyrighted images as training data. Depending on the outcomes of cases like Getty Images vs Stability AI and multiple artists vs Midjourney/Stability AI, terms of use may change in the future.
• Disclosure Obligation for Client Work: When using AI-generated images in commercial design projects, disclosing this to clients is consistent with professional ethics. Some industries are moving toward mandatory AI usage disclosure.

5.3 Portrait Rights and Existing Work Imitation Issues

• Celebrity Face Generation: Using AI to generate celebrity faces for commercial purposes or to spread false information can result in legal issues such as portrait rights violations and defamation. Most tools filter this, but circumvention is not impossible.
• Imitating Existing Artist Styles: Using a specific artist's name in a prompt to imitate their style is in a legal gray area. While style itself is not subject to copyright protection, there is significant ethical controversy, and some tools (Midjourney, etc.) restrict the use of living artist names.

Conclusion: Finding the Right AI Image Tool for You

The AI image generation tool ecosystem of 2026 is richer and more mature than ever before. From Midjourney's exceptional artistic quality to DALL-E 3's intuitive natural language understanding, Stable Diffusion's unlimited freedom, Adobe Firefly's copyright safety, and Ideogram's text rendering capability, each tool leverages its own strengths to fulfill different needs.

If we were to recommend an optimal combination for free users, the most practical approach would be to use Google ImageFX + Playground AI (tools with generous free quotas) as your main tools, Ideogram for images containing text, and DALL-E 3 (ChatGPT Free) as a supplementary tool when high-quality results are needed.

The best value tool when upgrading to paid depends on your purpose. If overall image quality and versatility are your top priority, Midjourney Standard ($30/mo) is the best choice. If safe usage in business environments is important, Adobe Creative Cloud subscription (includes Firefly) is ideal. If text-inclusive design is your primary purpose, Ideogram Plus ($20/mo) is the most reasonable option.

AI image generation technology continues to evolve, and each tool's free policies and features change frequently. The key is not to lock yourself into a single tool, but to flexibly combine tools that match your purpose and workflow.
