How to describe an image before generating it
Specify the subject, composition, light, and visual style without burying your idea in unrelated adjectives.
Start with a visible subject
Name the subject and its relationship to the scene. “A ceramic cup on a wooden windowsill” is easier to interpret than a list of moods. Add the most important position or action next. If a detail is optional, keep it out of the first version of the prompt.
Use lighting and composition deliberately
Soft window light, an overhead view, and a close crop each change the picture in a different way. Choose details that support the subject. For a product image, describe the background and the space needed for text, rather than asking the model to invent a slogan inside the image.
Change one thing at a time
Generate a first prompt, then test it in your image tool. If the composition works but the mood does not, change the lighting or color direction while keeping the subject stable. Record the setting that produced a useful result. Model-specific syntax should be checked in that tool’s documentation.
