The Ultimate ChatGPT Image Prompting Guide 2025

ChatGPT's image generation (powered by DALL-E 3 and GPT Image 2) has become genuinely excellent. The gap between a bad prompt and a great image is almost always the prompt itself.

This guide teaches you exactly how to write prompts that produce professional, usable images — not generic AI-looking output.

THE IMAGE PROMPT FORMULA

Every great image prompt has 5 elements:

[SUBJECT] + [STYLE] + [LIGHTING] + [COMPOSITION] + [TECHNICAL SPECS]

Example: "A professional woman in her 30s reviewing documents at a modern desk [SUBJECT], in the style of editorial photography [STYLE], warm afternoon sunlight through a window [LIGHTING], mid-shot with shallow depth of field [COMPOSITION], photorealistic, 4K [TECHNICAL SPECS]."

Generic prompt: "A woman at a desk" Specific prompt: The full example above

The difference in output quality is dramatic.

GPT IMAGE 2: WHAT'S NEW

GPT Image 2 is OpenAI's most advanced image model (as of 2025). Key improvements:

• Near-perfect text rendering: logos, signs, labels with accurate text
• Instruction following: it actually does what you say
• Consistency: generate multiple images with consistent characters/scenes
• High resolution: up to 2K output
• Faster generation than previous models

To use GPT Image 2: In ChatGPT, go to a conversation and switch to image generation mode, or use the DALL-E icon.

PROMPT CATEGORY 1: PROFESSIONAL PHOTOGRAPHY

For realistic photos of people, products, and places:

Formula: "Photograph of [subject]. Shot on [camera]. [Lighting]. [Background]. [Composition]. Photorealistic. High resolution."

Examples: "Photograph of a CEO reviewing financial reports, shot on Sony A7III 85mm f/1.8, natural window light, modern glass office background blurred, shoulders-up, photorealistic."

"Product photograph of a luxury watch on a dark marble surface, studio lighting with soft box and rim light, minimal composition, commercial photography style."

"Street photography of a busy Tokyo intersection at night, Sony 35mm f/2, neon reflections on wet pavement, documentary style, candid."

PROMPT CATEGORY 2: BRAND DESIGN & LOGOS

GPT Image 2 finally handles text well:

"Create a logo for a company called 'Vertex AI Labs'. Minimal design. Sans-serif typography. Blue and white colour palette. Clean, corporate tech style. The word 'Vertex' should be in bold, 'AI Labs' smaller below."

"Design a social media banner for [brand name]. Dimensions: 1200x628. Headline: '[text]'. Brand colours: [colours]. Include a call-to-action button with text '[CTA text]'. Professional, modern design."

"Create a product label for a skincare brand called 'Lumina'. Clean, elegant, white and gold. The label text should read: 'Lumina Hydrating Serum — 30ml'. Minimalist design."

PROMPT CATEGORY 3: AI HEADSHOTS

Covered in detail in the AI Headshot Prompt Pack, but here's the core formula:

"Professional headshot of a [man/woman], [age range], [brief description]. [Clothing]. [Background]. [Lighting style]. [Composition: shoulders-up / waist-up]. Photorealistic, sharp focus on eyes."

Tips for consistency:

• Upload a reference photo and say "Match the face from the reference photo"
• Keep all other elements the same to iterate on one variable at a time

PROMPT CATEGORY 4: MARKETING & SOCIAL CONTENT

For social media posts, ads, and promotional images:

Instagram post: "Square social media graphic (1:1 ratio). Bold headline: '[TEXT]'. Subheading: '[TEXT]'. Background: [describe]. Design style: clean, modern, [brand personality]. Brand colours: [colours]. No stock photo feel."

Instagram Story / TikTok: "Vertical graphic (9:16). Bold text overlay: '[TEXT]'. Background image of [describe]. Text should be white with dark drop shadow. Clean, mobile-first design."

Facebook Ad: "Facebook ad creative. Image shows [describe scene]. Text overlay: '[headline]'. Design should create visual curiosity and stop the scroll. [Brand colours]. Professional."

PROMPT CATEGORY 5: PRODUCT MOCKUPS

For showing your digital products on devices or in lifestyle contexts:

"Mockup of a mobile app shown on an iPhone 15 Pro Max screen. The screen shows [describe the app interface]. The phone is held in a hand against [background]. Photorealistic, commercial product photography style."

"Laptop mockup showing a website design. MacBook Pro on a clean white desk with coffee mug. The screen shows [describe the website]. Minimal, modern workspace aesthetic."

"Book cover mockup. The book is titled '[title]' by '[author name]'. Cover design: [describe]. Shown on a dark wooden table with soft side lighting. 3/4 angle view."

PROMPT CATEGORY 6: ILLUSTRATION & ART STYLES

For non-photographic content:

"Flat design illustration of [subject]. Minimal, geometric style. Colour palette: [colours]. No gradients, no shadows, no textures. Clean vector art aesthetic."

"Watercolour illustration of [subject]. Soft washes of colour, visible brushwork, white paper showing through. Whimsical, artistic. [Colour palette]."

"3D render of [subject]. Clean, glossy materials. Soft studio lighting. White background. Isometric perspective. The style of modern tech product renders."

"Vintage poster design for [event/brand]. Art Deco typography. Muted colour palette of [colours]. Ornamental border. Printed poster texture."

PROMPT CATEGORY 7: INFOGRAPHICS & DATA VISUALS

"Create an infographic showing [data/process/comparison]. Style: clean, professional. Colour scheme: [colours]. Include: [specific elements — icons, labels, numbers]. Horizontal layout. White background. Clear hierarchy."

"Flow chart diagram showing the steps to [process]. Minimal design. Each step in a rounded rectangle. Arrows connecting steps. Text labels for each step. [Colours]. Clean, readable."

PROMPT CATEGORY 8: AI ACTION FIGURES & FUN PROMPTS

These went viral for a reason:

"Create a collectible action figure toy of [describe the person or character]. They're in a clear plastic package with a cardboard backing. The packaging says '[character name]' at the top and '[description/tagline]' below. The figure comes with accessories: [list accessories]. Photorealistic toy photography."

"Barbie doll version of [describe person/profession]. In a pink box with 'Barbie' branding. The doll is wearing [clothing]. Accessories: [items]. Background of box: [colour/pattern]. Photorealistic toy product shot."

THE 10 MOST COMMON IMAGE PROMPTING MISTAKES

1. Too vague: "A nice photo of a sunset" vs "A dramatic sunset over the Pacific Ocean, shot from a beach, long exposure, golden and orange tones, silhouetted palm trees in the foreground"

2. Conflicting styles: Asking for "photorealistic watercolour" creates confusion. Pick one.

3. Forgetting lighting: Lighting is 50% of the image. Always specify it.

4. No composition: "Shoulders up", "mid-shot", "close-up", "wide angle" — always include this.

5. Over-complicated prompts: 200-word prompts often produce worse results than 50-word focused prompts.

6. Not specifying text: If you want text in the image, put it in exact quotes.

7. Forgetting the background: Always describe the background, even if it's "clean white background".

8. No style reference: "In the style of [photographer/artist/aesthetic]" dramatically improves output.

9. Not iterating: Your first prompt is rarely the best prompt. Iterate 3-5 times.

10. Wrong aspect ratio: Always specify the ratio you need (1:1, 16:9, 9:16, 4:5).

QUICK REFERENCE: STYLE KEYWORDS THAT WORK
