Learn how to write controllable commercial image prompts for ChatGPT and GPT Image, covering subject, composition, lighting, brand constraints, iteration and QA.
Commercial images need a clear job: explain the product, communicate the selling point, and fit the final placement. For ChatGPT and GPT Image, structure matters more than keyword volume.
Define the use case, audience, selling point and aspect ratio before describing style.
Before style words, write the business brief: placement, audience, selling point, product features, copy space, and constraints. This turns a vague request into an art direction.
Task: create a commercial image for [placement].
Subject: [product/service], preserve [key features].
Composition: [camera angle, crop, whitespace].
Style: [brand mood, industry feel].
Lighting: [studio/natural/softbox/rim light].
Background: [setting, props, colors].
Avoid: [wrong text, extra logos, distorted packaging].
Output: suitable for [poster/ad/banner/product page].
Specify the features that must not change: shape, material, color, label position, and package ratio.
Commercial images often need copy space. Ask for whitespace intentionally: right-side copy area, top headline zone, or a clean lower third for CTA.
Use terms such as softbox studio lighting, clean shadows, glossy reflections, matte texture, rim light, and premium product photography.
Change one variable at a time: lock subject and composition, tune background and lighting, then refine props and copy space.
Round one explores direction. Round two locks layout and tunes background. Round three fixes production issues such as text artifacts, distortion, shadows and crops.
Create a premium ecommerce product ad for [product]. Place it [position], preserve [visual features]. Use [background/material] with minimal [props]. Soft studio lighting, clean shadow, refined reflection, [brand mood]. Aspect ratio [ratio], leave [area] for copy. Avoid gibberish text, extra logos, distorted packaging.
For a sugar-free sparkling water ad, define the goal as freshness, zero sugar and low burden. Use a left-side can, blue ice, light condensation and 40% right-side copy space. Iterate by reducing props, cleaning copy space and correcting package edges.
Most unusable commercial outputs fail because the prompt does not specify placement, copy space, product constraints or negative requirements.
