Prompt Engineering for Images Prompt engineering is the art and science of formulate instructions effective for AI image generation tools. A well-structured prompt is the key to high qualities that correspond exactly to the creative vision desired. Structure of an Effective Prompt 1 Main Subject Clear and specific description of the main subject of the image (person, object, scene, landscape). 2 Attributes and details Specific characteristics, colours, materials, expressions, postures, lighting, season, time of day. 3 Artistic style References to artistic styles, artists, periods, techniques (photorealistic, illustration, oil painting, watercolor). 4 Technical parameters Technical specifications such as quality, resolution, aspect ratio, depth of field, perspective. 5 Modifiers and Weights Keywords to emphasize elements (::5), reduce elements (::0.5) or exclude elements (no, without). Best Practices Be specific and detailed The more details you provide, the more AI will understand your vision. Avoid vague terms like "nice" or "interesting". Use visual references Cite specific artists, films, photographers or styles to guide aesthetics (e.g. "in the style of Monet" or "as a photo by Annie Leibovitz"). Research and Development Use the initial results to improve the prompt by adding details or editing items that do not work. Use Advanced Parameters Use the specific parameters of each instrument (--ar 16:9, -chaos 30, -styles 1000) for more precise control. Conceptual scheme of the prompt engineering process for AI image generation Example of Prompt and Result Basic Prompt (Weak): A woman in a cafe. Optimized Prompt (Strong): A young woman sitting in an open-air Parisian café sipping an espresso. She wears an elegant blue dress and a straw hat. Warm lighting in the late afternoon, bokeh in the background. Photorealistic style, inspired by Steve McCurry, high resolution, sharp focus on the subject, shallow depth of field. --ar 4:5 --styles 750 Key elements: Specific subject (young woman), setting detailed (outdoor Parisian coffee), attributes (blue dress, hat of straw), lighting (late afternoon), style (photorealistic, Steve McCurry), technical parameters (high resolution, bokeh, depth of field), modifiers (-ar 4:5, -stylize 750). Note: Parameter syntax may vary between different imaging tools
