Image Prompt Guidelines

Write clear, specific prompts for the built-in image tools. Describe the intended image, the requested changes, and the details that must be preserved.

Core principles

• When the user's description is already specific, organize it and resolve ambiguity without adding creative requirements.
• When the description is broad, add only composition, lighting, or material details that support the goal. Do not invent people, props, brands, slogans, or story elements.
• State the intended use, such as a website hero image, product display, or educational diagram, to guide composition and information density.
• Use observable visual requirements instead of vague praise. For example, write "soft side lighting with natural skin texture" rather than "premium quality."
• Include only fields relevant to the task. Colors, positions, copy, and constraints in examples are not defaults for every request.

Distinguish creation and editing intent

• New image: Describe the scene, subjects, and their relationships, then add style, composition, and necessary constraints.
• Creation from references: Explain what each reference contributes, such as character appearance, palette, materials, or composition. A reference is not automatically an edit target.
• Editing an existing image: State what to change and what to preserve. Avoid describing a local edit as a complete redraw.
• Compositing: Identify the base image, subject to insert, and style reference by image number. Specify placement, scale, perspective, and lighting relationships.
• Image series: Describe each image's subject or variation separately. Repeat the style and character constraints needed for consistency.

Prompt structure

Use the following structure as needed. Omit irrelevant fields; there is no need to fill in every line.

Intended use: Where the image will be used
Primary request: What to generate or change
Input images: Role of Image 1; role of Image 2
Scene and background: Environment, time, and background elements
Subject: Appearance, action, count, and relationships
Style and medium: Photography, illustration, watercolor, 3D rendering, etc.
Composition and viewpoint: Framing, viewing angle, subject placement, and negative space
Lighting and mood: Light direction, softness, and overall mood
Palette and materials: Required colors, surface qualities, and details
Text in image: Exact wording and placement
Change only: Parts that may change in this iteration
Preserve: Content that must remain unchanged
Avoid: Exclusions relevant to this task

Key constraints

• Composition: Specify left/right placement and negative space only when requested or required by the layout. Do not arbitrarily choose a side for copy.
• Text in images: Quote the exact wording, preserving capitalization, punctuation, and language. Specify hierarchy and placement; do not translate, rewrite, or add copy unless requested.
• Local edits: Keep preservation requirements compatible with the change. When replacing a background, preserve the subject's outline, colors, and position without also requiring the background to remain unchanged.
• Character consistency: Specify the facial features, hairstyle, body shape, or clothing to preserve. When the user requests a new pose, do not lock the original pose.
• Transparent assets: Describe the complete subject, clear edges, and a clean background, and state the transparent-background goal. Do not substitute a drawn checkerboard or white background for transparency.
• Charts and educational diagrams: Use supplied or confirmed text, values, and relationships. Resolve missing essential content instead of inventing data or sources to fill the image.
• Iteration: State the current adjustment and repeat constraints that still apply, so unrelated details remain consistent.

Examples

Generate a product image

Intended use: A wide hero image for a coffee product page
Primary request: A simple product photograph of a ceramic coffee mug
Scene and background: A clean, light-colored studio background
Style and medium: Photorealistic product photography
Composition and viewpoint: Show the entire mug and leave usable negative space for page copy
Lighting and materials: Soft studio lighting with natural reflections on the ceramic glaze
Avoid: Text, logos, watermarks, and extra props

Replace only the background

Input images: Image 1 is the product photo to edit
Primary request: Replace the background with a warm sunset gradient
Change only: The background area
Preserve: Product shape, edges, label text, colors, size, and position in the frame
Avoid: Adding text or props, or changing the product's appearance

• For complete examples by scenario, read Sample prompts and use only the parts relevant to the current request.
