How to Write Better AI Image Prompts: A Practical Guide

A practical framework for writing AI image prompts that actually work — structure, power words, common mistakes, and how to iterate toward the image in your head.

The single biggest lever on AI image quality isn't the model — it's the prompt. Here's a practical framework you can apply to any model on ArtifyAI to get closer to the image in your head.

A simple prompt structure

[Subject] + [Action/Pose] + [Setting] + [Style] + [Lighting & detail]

Example: "A red fox sitting on a mossy log, in a misty pine forest at dawn, watercolor style, soft rim lighting, fine detail."

Be specific where it matters

  • ❌ "a person" → ✅ "a young woman with curly auburn hair in a linen jacket"
  • ❌ "nice background" → ✅ "a sunlit Mediterranean courtyard with terracotta tiles"
  • ❌ "good lighting" → ✅ "golden-hour backlight with long shadows"

Power words that move the needle

  • Quality: highly detailed, sharp focus, professional photography, 8k
  • Lighting: soft light, golden hour, dramatic shadows, studio lighting
  • Composition: close-up, wide shot, rule of thirds, symmetrical
  • Mood: serene, moody, whimsical, cinematic

Match the model to the prompt

Prompts behave differently across models:

  • Text in the image? Use Ideogram V3 and put the words in quotes: headline "NEON NIGHTS".
  • Photorealism? Google Imagen 4 or FLUX 1.1 Pro respond well to camera and lighting language.
  • Drafting? FLUX Schnell is free and fast — iterate here first.

Common mistakes

  1. Cramming everything in. Start simple, then add detail. Overloaded prompts confuse the model.
  2. Vague adjectives. "Beautiful" means little; describe what makes it beautiful.
  3. Ignoring aspect ratio. Pick 16:9 for landscapes, 9:16 for phone wallpapers, 1:1 for avatars.
  4. Giving up after one try. Great results come from iteration, not luck.

Iterate like a pro

Generate, look at what worked and what didn't, change one thing, and run it again. Because free models are fast and cost nothing, you can afford to explore widely before committing a credit to a final, high-fidelity render.

A reusable starter template

"[subject], [doing what], in [setting], [art style], [lighting], highly detailed" — fill in the brackets, generate, then refine. Keep a note of prompts that work; your personal prompt library is the fastest way to improve.
