Pro Tips for Better AI Image Generation
Write Better Prompts
The quality of your output depends heavily on your prompt. Here are some tips:
- Be specific: Instead of "a dog," try "a golden retriever puppy sitting in a sunlit meadow, soft bokeh background, professional photography"
- Specify style: Add terms like "digital art," "watercolor," "cinematic lighting," or "minimalist"
- Include technical details: Mention aspect ratio, lighting direction, camera angle, or color palette
Use Image-to-Image for Refinement
Start with a rough sketch or reference image and use image-to-image mode to refine it. This gives you much more control over composition and layout than text-to-image alone.
Leverage AI Image Tools
Beyond generation, tools like Background Remover, Image Upscale, and Face Swap can take your outputs to the next level.
