MidJourney Mastery
Prompting Fundamentals
Subject-first grammar, lighting keywords, style modifiers
The foundation of every great MidJourney image starts with how you structure your prompt. Lead with the subject, layer in environment and lighting, then close with style modifiers. Order matters - MJ weights early tokens more heavily.
- Put the most important element first - MJ weights early tokens more heavily
- Stack 2-3 lighting keywords for depth: "studio lighting, rim light, soft shadows"
- Use "clean background" or "white background" for assets you need to extract
- Avoid negative prompts unless necessary - describe what you want, not what you don't
CREF - Character Reference
Lock face and proportions across generations
CREF (Character Reference) is MidJourney's way of maintaining character consistency. Upload a reference image and MJ will match the character's face, proportions, and overall design. This is how you generate 20 poses of the same character without them morphing into someone else.
- --cw 100 locks everything: face, outfit, proportions, accessories
- --cw 0-50 locks mostly face/expression - lets outfit and style change
- Use your best generation as the CREF source - quality in = quality out
- Combine with OREF for absolute consistency (face from CREF + weapon from OREF)
OREF - Object Reference
Lock specific objects and accessories across generations
OREF (Object Reference) locks specific objects - weapons, accessories, logos, vehicles - across generations. While CREF handles the character, OREF handles the stuff they carry. Together they give you full production-grade consistency.
- Isolate the object on a clean background for best OREF results
- OREF works best for distinct objects: weapons, vehicles, logos, jewelry
- Stack CREF + OREF together for character + object consistency
- Lower --ow (50-75) for "inspired by" rather than exact match
Style Consistency
Maintain visual coherence across a series
Creating a visually cohesive series requires more than just CREF. Style references (--sref), consistent prompt structure, and deliberate style tokens keep your entire project looking like it came from one artist, not a random generator.
- Keep a "style bible" - save your best generation and use it as --sref for everything
- Repeat the same style tokens in every prompt: "clean flat illustration, thick outlines"
- Use --sref + --cref together for maximum consistency
- Create a template prompt and only swap the action/pose for each generation
Aspect Ratios & Composition
The --ar flag, framing, and negative space
Aspect ratio isn't just cropping - it changes how MJ composes the entire image. A 1:1 square centers the subject. A 16:9 creates cinematic depth. A 9:16 produces vertical portraits. Understanding this lets you generate production-ready assets without post-processing.
- 1:1 for avatars and icons - forces tight, centered composition
- 16:9 for hero images and banners - creates cinematic negative space
- 2:3 or 3:4 for character design sheets - shows full body
- 9:16 for mobile wallpapers and story-format content
