# GPT Image Hub prompt engineering guides

Direct-answer guides for AI image prompt writing, structured for answer engines and agents.

- [Best GPT Image Prompts for Product Photography](https://www.gptimagehub.com/guides/best-gpt-image-prompts-for-product-photography): The best GPT Image product photography prompts specify the exact product, surface, background, lighting, camera angle, composition, brand-safe text, and intended commerce use case. Strong prompts also separate product facts from style direction so agents can adapt them without changing the product identity.
- [How to Write Consistent Character Prompts](https://www.gptimagehub.com/guides/consistent-character-prompts): Consistent character prompts describe a stable character bible: age range, silhouette, face shape, hair, clothing, palette, personality cues, recurring props, and the exact output format. The prompt should also state which details may change between poses and which details must remain fixed.
- [GPT Image Prompt Examples by Style](https://www.gptimagehub.com/guides/gpt-image-prompt-examples-by-style): A good style prompt names the target visual family, then adds medium, composition, palette, lighting, texture, camera, and output use case. Style words are most useful when paired with concrete constraints such as line weight, lens, typography, material, or layout grid.
- [How to Write GPT Image Prompts for UI Mockups](https://www.gptimagehub.com/guides/gpt-image-ui-mockup-prompts): Good GPT Image prompts for UI mockups name the product, the screen and its main components, the device or frame it appears in, the visual style, and the exact text that must be readable. List components in reading order and keep on-screen copy short, because the model renders a few large labels far more reliably than paragraphs of interface text.
- [How to Write Poster Prompts for GPT Image 2](https://www.gptimagehub.com/guides/gpt-image-poster-prompts): Effective poster prompts define the poster's purpose, a single focal image, the composition and negative space, the exact title and supporting text with their placement, the illustration or photo style, the palette, and the aspect ratio. Posters fail most often on crowded composition and long text, so state where the empty space goes and keep typography to a title and one or two short lines.
- [How to Write Logo and Brand Identity Prompts](https://www.gptimagehub.com/guides/gpt-image-logo-branding-prompts): Logo and brand prompts work best when they state the brand name exactly, what the business does, the mark type (wordmark, lettermark, symbol, or emblem), two or three personality traits, color limits, and the presentation format. For a full identity board, list the deliverables, such as logo, typography, palette, and social templates, so the model lays them out as a brand guideline page.
