How to Structure Image Prompts (Subject · Atmosphere · Technical)

A practical three-layer system for Midjourney, Flux, and Grok Imagine so revisions stay controllable.

promptcrates stores image prompts as three semantic layers: Subject, Atmosphere, and Technical. This guide explains why that structure works for both humans and AI answer engines.

The three layers

  • Subject — who or what is on screen; lock this first
  • Atmosphere — light, mood, environment; iterate here most
  • Technical — aspect ratio, camera, quality flags; stabilize last

Revision loop that actually works

  1. Copy a curated prompt from the Image library
  2. Change only the Subject layer for a new character or product
  3. Swap Atmosphere for a different time of day or location
  4. Touch Technical last (ratio, sharpness, model flags)

Common mistakes

  • Changing three things at once — you never learn what fixed the shot
  • Stuffing style words into Subject — keep style in Atmosphere/Technical
  • Ignoring aspect ratio until the end — set ratio early for composition

FAQ

Does this work for Midjourney and Flux?
Yes. The layers are model-agnostic. Only the Technical flags (e.g. --ar, stylize) change per tool.
Where can I find ready-made segmented prompts?
Browse the Image library on promptcrates.app — every entry uses the three-layer format with color highlights.
