Tips for Better AI Image Prompts
The quality of your results depends heavily on prompt quality. Use this structure for best results:
[Subject] + [Style] + [Lighting] + [Camera angle] + [Technical quality terms]
Example: “A female barista making coffee in a modern café, cinematic photography style, warm golden hour lighting, eye-level shot, 35mm lens, photorealistic, 4K”
Avoid vague prompts like “a nice person” — the more specific and visual your description, the better the result.
AI Image Generator FAQ
Which free AI image generator has no restrictions?
Leonardo.ai’s free tier (150 tokens daily) has the most generous limits with commercial use rights. Adobe Firefly offers 25 credits monthly with full commercial licensing — best if copyright safety is your priority. For unlimited free generation, self-hosting Flux models via Hugging Face Spaces or locally has no daily cap but requires technical setup.
Are AI-generated images copyrighted?
This varies by jurisdiction and is still evolving legally. In the US, the Copyright Office has ruled that AI-generated images without human creative input are not copyrightable. For commercial use, choose tools with explicit commercial licenses (Adobe Firefly, Leonardo.ai) and review each platform’s specific terms of service.
Final Thoughts
For commercial-safe images, start with Adobe Firefly. For volume and daily free usage, Leonardo.ai is unmatched. For the highest artistic quality, Midjourney (paid) remains the standard. Most creators end up using 2–3 tools depending on the specific need — there’s no single best AI image generator for every use case.
