Prompt Anatomy: Basic Structure
An effective prompt consists of four key elements: subject, environment, style, and technical parameters. Writing "A close-up portrait of a middle-aged woman with silver hair, soft studio lighting, shot on Canon 5D, bokeh background, professional fashion photography" instead of "A portrait of a woman" dramatically improves output quality. The more specific the subject, the more accurate results AI produces.
Style and Reference Techniques
Providing references to specific artists or visual styles helps achieve consistent results. You can use references like "In the style of Ansel Adams" (black-and-white photography), "digital art by Artgerm" (anime-style illustration), or "concept art for a AAA video game." Specifying an era is also effective: "1970s retro poster design" or "Renaissance oil painting technique." To mix multiple styles, write something like "blend of Art Nouveau and cyberpunk aesthetics."
Lighting and Composition Control
Lighting is the most critical element that determines the mood of an image. Expressions like "Golden hour lighting," "dramatic side lighting," "neon-lit environment," or "overcast diffused lighting" significantly shape outputs. For composition, use cinematic terms like "rule of thirds," "bird's eye view," "worm's eye view," "extreme close-up," or "wide establishing shot."
Negative Prompt and Improvement Strategies
Clearly specifying unwanted elements improves output quality. In Stable Diffusion's negative prompt field, add common problems like "blurry, low quality, distorted, watermark, text, extra fingers, bad anatomy, ugly." In Midjourney, use the "--no" parameter. Run the same prompt multiple times for different results, and lock in the best one with its seed number. If you like an image, you can generate similar variations with "--seed [number]."
