How to Write Better AI Image Prompts: 7 Easy Tips for Better Results

Knowing how to write better AI image prompts is the fastest way to improve your results. A vague prompt can still work, but a clear, specific prompt gives the AI more to work with — subject, style, lighting, mood, and composition — and the difference in quality is immediate.

1. Start with a clear subject

Begin by saying exactly what you want to see. Instead of “dog,” try “a golden retriever puppy sitting in a sunny kitchen.” The clearer the subject, the easier it is for the AI to build the image around it.

2. Add style and mood

Style words help shape the final look. Try phrases like “cinematic,” “watercolour,” “3D render,” “minimalist poster,” “dark fantasy,” “retro comic book,” or “photorealistic.” Mood words such as “peaceful,” “dramatic,” “playful,” or “mysterious” also make a big difference.

3. Describe lighting

Lighting can completely change an image. Try “golden hour sunlight,” “soft studio lighting,” “neon glow,” “moonlit scene,” “dramatic shadows,” or “bright natural light.” This gives your image more atmosphere and polish.

4. Include composition details

Composition tells the AI how the image should be framed. Useful phrases include “close-up portrait,” “wide landscape shot,” “centred subject,” “bird’s-eye view,” “low-angle shot,” or “symmetrical composition.”

5. Mention colours

Colour direction helps keep the result consistent. You might ask for “pastel colours,” “black and gold,” “muted earth tones,” “bright cyberpunk colours,” or “a clean white and blue palette.”

6. Avoid overloading the prompt

Long prompts can work, but too many competing ideas may confuse the result. Aim for one strong subject, one clear style, and a few supporting details. Think of it like giving directions, not writing a shopping list for the universe.

7. Try variations

The first result is rarely the final result. Try changing one part of the prompt at a time — the lighting, style, angle, or colours — so you can learn what improves the image.

Example AI image prompt

A photorealistic portrait of a friendly robot assistant sitting at a modern desk, warm studio lighting, soft shadows, clean blue and white colour palette, shallow depth of field, centred composition, high detail.

Frequently asked questions

What makes a good AI image prompt? A good AI image prompt describes one clear subject, a specific style, and a few supporting details — lighting, mood, or composition. The more precise you are, the more control you have over the result. You do not need a long prompt; you need a focused one.

How long should an AI image prompt be? Most good prompts are between 20 and 60 words. Short enough to stay focused, long enough to give the AI useful direction. Adding too many competing ideas at once can confuse the result — if you have several ideas, try them one at a time.

Why do my AI-generated images look generic? Generic results usually come from generic prompts. Adding a specific style word (like "cinematic," "watercolour," or "retro comic book"), a lighting description, and a composition detail moves the result away from the default and toward something with a distinct look.

Do the tips here work for all AI image tools? Yes — the principles of clear subject, style, lighting, mood, and composition apply across all the main tools (Midjourney, DALL·E, FLUX, Stable Diffusion). Each tool responds slightly differently to the same words, so the AiJoe Prompt Library has prompts tested across multiple tools if you want a head start.
