The 6-layer framework
Each layer below maps to a section of the builder. Fill in as many as you can for the most specific, on-brand prompt.
| Layer | What it captures | Example fragment |
|---|---|---|
| Concept | What kind of image this is | product still life |
| Subject | The person, product, or scene in full detail | dark amber glass serum bottle with gold dropper |
| Colors and materials | Specific descriptive language not hex codes | warm gray marble, cool purple undertones |
| Composition | Subject position and framing | centered, generous negative space |
| Lighting | Source, direction, and quality | soft diffused natural window light from the left |
| Camera and lens | Focal length and aperture | 100mm macro lens at f/4.0 |

Frequently asked questions about the Midjourney Prompt Builder
Yes. The Midjourney Prompt Builder on CropUp Ai lets you construct a prompt layer by layer instead of writing one from scratch. You pick each layer from a dropdown, watch the prompt assemble live, and when done hit Enhance with AI for three ready-to-use variations.
The builder runs on the same 6-layer framework used across every tool on the site: concept, subject, colors and materials, composition, lighting, and camera and lens. Each layer adds one specific instruction Midjourney can act on instead of leaving it to guess.
A prompt builder has you choose each layer yourself. A prompt generator writes the whole prompt for you from a plain description. Either way, the goal is the same: a consistent, on-brand AI image prompts generator experience - the builder gives you control over every layer, while a generator is faster when starting from an idea instead of a spec.
A good Midjourney prompt is specific in every layer not just the subject. Vague adjectives mean nothing to an AI while naming the actual technique gives it something to act on.
Look for a builder that covers composition and lighting not just subject and colors, shows a live preview of the assembled prompt, and does not gate the basics behind a paywall. The CropUp Ai Midjourney Prompt Builder meets all three - free, no account required, live preview, and AI-enhanced variations.
