How to Create AI Image Prompts
Quick Answer
A good AI image prompt describes the subject, style, composition, mood, colors, background, aspect ratio, and what to avoid. The clearer your visual direction is, the easier it is for the image model to create something close to your goal.
What Makes a Good Image Prompt?
Image generation models respond well to concrete visual detail and struggle with vague or purely conceptual requests. A prompt like "a picture about success" leaves too much open to interpretation, while a prompt describing an actual scene, style, and mood gives the model something specific to render.
Define the Image Goal
Start by clarifying what the image is for: a social media post, a website banner, a product mockup, or a print ad. The purpose affects composition, orientation, and how much visual detail versus negative space you need, so state it clearly before describing the visual itself.
Describe Subject, Style, and Composition
Describe exactly what should appear in the image, the artistic or photographic style you want, such as flat illustration, 3D render, or realistic photography, and how elements should be arranged, such as centered, close-up, or wide shot. The more concrete this description, the less the model has to guess.
Choose Colors, Lighting, and Mood
Specify a color palette or mood, such as warm and earthy or cool and minimal, and describe the lighting if it matters, such as soft natural light or dramatic shadow. These details have a big impact on how professional or specific the final image feels.
Add Aspect Ratio and Platform Context
State the aspect ratio or dimensions you need, since a square Instagram post, a wide banner, and a vertical Story require very different compositions. Mentioning the platform helps the model consider what tends to work visually in that format.
Use Negative Prompts and Avoid Lists
Some tools support explicit negative prompts, while others just let you describe what to avoid in plain language. Either way, stating what you don't want, such as "no text," "no people," or "no clutter," helps prevent common unwanted elements from appearing.
Image Prompt Template
"Create a [style] image of [subject] for [purpose]. Composition: [composition detail]. Colors and mood: [colors/mood]. Lighting: [lighting]. Aspect ratio: [ratio]. Avoid: [things to avoid]."
Examples for Logos, Banners, and Ads
For a banner: "A wide, minimal banner image showing a laptop and coffee cup on a wooden desk, soft morning light, warm neutral tones, plenty of negative space on the left for text, 16:9 aspect ratio."
For an ad visual: "A clean product photography style image of a skincare bottle on a marble surface, soft studio lighting, pastel background, centered composition, square aspect ratio, no text."
Final Checklist
- The subject and purpose of the image are clearly stated
- Style, composition, and mood are described concretely
- Colors and lighting are specified if they matter
- Aspect ratio matches the platform or use case
- Unwanted elements are explicitly excluded
