Start with the outcome
Describe what you want to create, where it will be used and the visual style. Mention the aspect ratio when it matters, such as a YouTube thumbnail, portrait post or website banner.
Describe the subject
Include the main subject, environment, composition, camera perspective and important objects. Specific instructions are more useful than a long list of vague adjectives.
Control text carefully
If an image needs readable text, specify the exact wording and keep it short. Always inspect the final image for spelling and layout errors.
Edit instead of restarting
When the overall image is good, ask for a focused change rather than rewriting the entire prompt. This can preserve useful composition while correcting one element.
Think about rights
Do not assume that an AI-generated image automatically gives you permission to reproduce logos, copyrighted characters or another person's likeness for every purpose. Check the applicable service terms and rights.
Bottom line
Good AI image results come from clear composition instructions and iterative editing, followed by a human review of accuracy and rights.
