Things to Watch Out for With AI Image Generation
On Copyright
Copyright for AI-generated images continues to be debated globally. For commercial use, keep these points in mind:
- Check each tool's terms of service
- Avoid prompts that imitate the style of specific artists or brands
- Adobe Firefly is the safest as its training data is rights-cleared
- Legal review is recommended for significant commercial applications
Prompt Writing Tips
Good image generation requires good prompt writing, regardless of the tool.
1. Be specific: "Sunset over Mt. Fuji reflected in a lake, autumn foliage" beats "a nice landscape" 2. Specify style: "Photorealistic," "watercolor," "flat design," etc. 3. Specify composition: "Bird's eye view," "close-up," "wide-angle lens," etc. 4. Negative prompts: Specify elements you don't want — especially effective in Stable Diffusion
Conclusion
In 2026, each AI image generation tool has a clear strength. Understand the breakdown: DALL-E 3 for accessibility, Midjourney for artistic quality, Stable Diffusion for customizability, and Adobe Firefly for commercial safety — then choose based on your goal.
