AI Image Prompt Generator

In short An image prompt works best when it names six things explicitly: subject, style, lighting, composition, camera or lens character, and the aspect ratio. Image models do not infer the ones you leave out — they fill them from whatever dominates their training data, which is why an unspecified prompt tends to produce the same centred, evenly lit, mid-shot look every time. Naming lighting alone changes an image more than any other single word: "golden hour", "overcast", "harsh directional" and "softbox" produce visibly different pictures of the same subject. Composition is the second biggest lever, because it decides where the subject sits and how much room is around it. Two practical points. Order matters in most models — terms near the front carry more weight, so put the subject first and the modifiers after. And a negative prompt is not universally supported: it works in Stable Diffusion and its descendants, is handled with a parameter in Midjourney, and is ignored entirely by several others, so check before relying on it to remove something.
