How to Write AI Image Prompts

Write better text-to-image prompts using subject, style, composition, and light. Includes examples and a repeatable AI image prompt formula.

How AI Image Generation Works

In Gab AI you describe a picture in the same composer you use for chat. The request is routed to an image model — you do not need a separate Midjourney or ChatGPT account. The model was trained on image–text pairs, so it translates your words into pixels. A single adjective, “cinematic” versus “flat,” can change the whole frame. You can also upload a photo and ask for an edit: change one object, extend the canvas, or restyle the shot. Generation and editing share the same credit balance.

Anatomy of an Image Prompt

Every strong image prompt has four core building blocks. Think of them as layers you stack on top of each other to give the AI a complete picture of what you want.

Here's an example that hits all four building blocks. Notice how each phrase adds a specific layer of information for the AI.

Vague vs. Detailed Prompts

The difference between a forgettable AI image and a breathtaking one almost always comes down to specificity. Compare these two prompts:

Popular Style Keywords

Having a vocabulary of style keywords in your toolkit makes image prompting much easier. Here are some of the most effective ones to experiment with:

Combine styles for unique results

You can mix style keywords to create unique aesthetics. Try "watercolor meets cyberpunk" or "anime style with cinematic lighting" to get results that stand out from typical generations.

Aspect Ratios & Composition Tips

Many image generators let you control the aspect ratio. Choosing the right one can dramatically improve your results:

Iteration is key

Don't expect perfection on the first try. Professional AI artists typically generate 5–15 variations of a prompt, tweaking keywords each time. Small changes like swapping "sunset" for "blue hour" or "close-up" for "wide angle" can yield dramatically different — and often better — results.

Iteration Tips

Getting great AI images is an iterative process. Start with a basic prompt covering your subject and style, generate a few images, then refine. If the lighting is off, add lighting keywords. If the composition feels wrong, specify a camera angle. If the mood isn't right, adjust your atmosphere words.

  1. Subject — What is in the image? Be specific. Instead of "a dog," say "a golden retriever puppy sitting in a field of wildflowers." The more detail you give about the subject, the less the AI has to guess.
  2. Style — How should it look? Specify an artistic style such as photorealistic, watercolor, digital art, oil painting, anime, pixel art, 3D render, or pencil sketch. You can even reference specific artistic movements like "Art Nouveau" or "Impressionist."
  3. Details & Composition — Add technical details that guide the composition. Mention lighting (golden hour, dramatic shadows, soft studio light), camera angle (bird's eye view, low angle, close-up macro), and aspect ratio when it matters. These details separate average prompts from stunning ones.
  4. Mood & Atmosphere — What feeling should the image evoke? Words like "serene," "eerie," "vibrant," "melancholic," or "whimsical" tell the AI about the color palette, contrast, and overall tone to use.
