How to write AI image prompts: five steps from subject to composition

1. Define the main subject

The subject is the most important element in the image. For product photography, start with the product type, shape, color, and material. Avoid several equally prominent objects unless you are creating a group display.

A transparent glass perfume bottle with pale amber liquid and a black cylindrical cap provides more details to check than a luxury perfume bottle. To match a real product, use a reference image you have permission to use.

• Subject: transparent glass perfume bottle.
• Appearance: pale amber liquid and a black cap.
• Completeness: the entire subject, with clear edges.

2. Give the subject a clear setting

Define a background color, placement, or environment. Two or three related elements are enough, such as a pale green wall, beige stone platform, and a plant to the side.

An ecommerce image should make the product stand out. A lifestyle image can include a few objects that explain its use. Avoid crowding a small image with too many props.

3. Set the mood with consistent lighting

Choose one main lighting condition, such as soft window light, even studio lighting, or sunset backlight. Add the direction and desired shadows, for example soft sunlight from the upper right with natural contact shadows.

Avoid combining direct midday sun, shadowless studio lighting, and late-night neon unless you have a specific mixed-light design. Conflicting light directions make results harder to control.

4. Describe the viewpoint, layout, and negative space

Specify a front view, overhead view, close-up, or centered or lowered subject. If you need a title, say where to leave a clean background and add accurate text afterward.

Aspect ratio defines the image shape; resolution defines its dimensions. Consider them separately. 1:1 works for square displays, 16:9 for landscape visuals, and 9:16 for portrait covers. Final dimensions depend on the platform and model.

5. Combine the prompt and check each detail

Use the following product photography prompt as a starting point. Check the subject, color, and setting first, then edges, shadows, and details. Adjusting one or two variables at a time makes the effect easier to understand.

• Check structure: are the cap, bottle, and shadows plausible?
• Check text: verify logos and labels individually; add typography afterward if needed.
• Check purpose: a concept image cannot replace factual product information.
