Expert Tips for Maximizing Your AI Image Generation Results

Crafting Effective Prompts

The key to generating exceptional AI images lies in writing detailed, specific prompts. Here are proven strategies for better results:

Be Specific and Descriptive: Instead of “cat,” try “a fluffy orange tabby cat sitting on a windowsill during golden hour, soft natural lighting, photorealistic style”.

Specify Technical Details: Include information about lighting, composition, colors, and mood to guide the AI more precisely.

Use Action Words: Describe what’s happening in the scene rather than just listing objects.

Optimize File Names: Use descriptive, keyword-rich file names like “AI-generated-sunset-landscape.jpg” instead of generic names.
