Midjourney Prompting: Style, Composition, and Parameters

Midjourney rewards vivid scene description plus a few well-chosen parameters. You do not need to memorize every flag—focus on composition first, then tune with stylize and aspect ratio.

Describe the shot, not the software

Write what the camera sees: subject, environment, lighting, materials, and art direction. Midjourney interprets photographic and illustration language well—"editorial beauty portrait, soft key light, peach makeup, pastel backdrop" beats a list of trending keywords.

Aspect ratio and composition

Use --ar 2:3 for portraits, --ar 16:9 for banners, --ar 1:1 for feeds. Composition hints like "centered subject," "negative space on the left for text," or "full-body fashion shot" reduce awkward crops.

Stylize and chaos

Higher --stylize pushes aesthetic polish; lower values stick closer to literal prompts. --chaos increases variation between rerolls. For client work, keep chaos moderate so iterations stay on-brand.

Consistency tricks

Reuse the same lighting phrase, lens phrase, and palette across a set. For characters, describe fixed traits (hair, outfit colors, accessories) and generate multiple poses separately rather than cramming every pose into one prompt.

When to use image prompts

Reference images help for layout and color grading. Combine a text brief with a reference for "match this mood, original subject."

Example set (fashion editorial)

Prompt A: "Editorial fashion photo, model in cobalt suit, walking through foggy pier at dawn, 35mm, muted film grain --ar 2:3 --stylize 250"

Prompt B: Same wardrobe and fog, "close-up portrait, wind in hair, soft rim light --ar 4:5"

Tune parameters in a deliberate order

Start with the image brief and a sensible aspect ratio. Only after the composition is close should you adjust style strength or variation. A style parameter changes how freely the system interprets your wording; it is not a quality dial with one universally correct setting. A higher value may produce a more expressive result, while a lower value can stay nearer to literal instructions. Use a small comparison set and keep the prompt and other settings constant so you can see what changed. Parameter names, ranges, and availability can change, so confirm syntax in the current Midjourney documentation before relying on it.

Variation controls are useful during exploration, but excessive randomness makes a campaign harder to art-direct. If you need a consistent product or character, keep the subject description and reference method stable and vary one scene detail at a time. If you need ideas, allow a wider spread, choose a direction, then narrow the next round. Do not confuse an unexpected result with a reproducible workflow; save the settings that produced the selected image.

Compose for the final placement

Choose the crop based on where the image will appear, then describe the camera view. A portrait ratio helps leave room for a full outfit; a wide banner needs a clear focal point and safe area for text. Aspect ratio cannot guarantee exact placement, so inspect the output and crop it in layout software. For a thumbnail, make the subject and contrast readable at small size. For a cover image, a wider scene may work, but avoid hiding essential details near the edges.

A practical prompt test

For a small bakery's seasonal banner, write a core brief: "A paper box of pastries on a wooden counter, morning window light, warm neutral palette, bakery interior softly out of focus, box on the right with clean space on the left, wide composition." Generate a baseline. If the box is centered, change only the composition instruction or use a supported reference/control. If the colors feel too stylized, reduce style influence while keeping the scene text intact. Add a version note for each result rather than stacking parameter changes and losing track of what worked.

Review before using commercially

Inspect food, packaging, lettering, and any recognizable marks for inaccuracies. Add exact logos or menu text only with permission and in a design tool. Check current service terms and client requirements before publishing. A generated image is a visual draft that may need selection, cleanup, crop work, and human approval; no particular parameter guarantees a publishable image.

FAQ

Why do hands fail? Crop tighter, simplify hand poses, or fix in a second pass.

Are version flags required? Follow current Midjourney docs for your subscription; describe scenes clearly regardless of version.

Can I use brand logos? Avoid trademarked logos in commercial work without permission.

Conclusion

Midjourney quality comes from art direction in text plus controlled parameters. Build small prompt families for each project instead of one-off random phrases.
