The image prompt formula
Subject + Setting + Style + Lighting + Colors + Format
“A flat-lay photo of a coffee cup, a notebook and a laptop on a light wooden desk (subject + setting), modern minimalist style (style), soft morning daylight (lighting), warm beige and green tones (colors), square format for Instagram (format).”
Prompts you can use
| Need | Prompt |
|---|---|
| Product background | “A clean marble surface with soft shadows and green leaves at the edges, empty space in the center for a product, bright natural light.” |
| Blog header | “Illustration of a person organizing tasks on a large calendar, flat vector style, purple and white, wide 16:9 format, no text.” |
| Social post background | “Abstract background with soft gradient shapes in [brand colors], lots of empty space for text, square.” |
| Presentation image | “A diverse team in a modern office discussing a chart on a screen, realistic photo style, natural light.” |
| Seasonal promotion | “Elegant lanterns and crescent moon decorations on a dark blue background, festive Ramadan mood, space for text at the top.” |
Tips for better results
- Be specific. “A cake” gives random results. “A two-tier white birthday cake with gold details on a pastel pink table” gives what you want.
- Ask for empty space where you’ll add text, then add the text in Canva or PowerPoint. AI is still unreliable at spelling words inside images.
- Iterate. Ask for small changes: “same image, but lighter background,” “make it more realistic.”
- Keep a consistent style. Reuse the same style words and brand colors in every prompt.
- Pick the right size: square (1:1) for Instagram, 16:9 for presentations and blog headers, 9:16 for stories.

Rules to follow
- Don’t copy brands, logos or characters. Don’t ask for images “in the style of” a living artist, or that imitate another company’s branding.
- Don’t create fake people or fake reviews presented as real customers or real events.
- Don’t misrepresent your product. If you sell a real product, show real photos of it. Use AI for backgrounds and concept images.
- Check commercial-use terms of the tool you use, especially on free plans.
- Be transparent where your industry or platform requires labeling AI-generated images.
Quick summary
- Use the formula: subject, setting, style, lighting, colors, format.
- Generate the image, then add text in a design tool.
- Keep a consistent style with the same keywords and brand colors.
- Respect brands and artists, and never use AI images to mislead customers.
