Essential Midjourney Commands

These are the core commands you'll use daily in Midjourney:

/imagine

The main command for generating images.

/imagine prompt: a serene lake at sunset, mountains in background, photorealistic

/describe

Upload an image and get prompt suggestions. Great for learning prompts.

/blend

Combine 2-5 images into a new creation.

/settings

Adjust your default generation settings.

/info

Check your subscription status and remaining usage.

Understanding the Image Controls

After generating images, you'll see buttons below. Here's what they do:

U1, U2, U3, U4

Upscale - Creates a high-resolution version of the selected image.

U1 = top-left, U2 = top-right, U3 = bottom-left, U4 = bottom-right

V1, V2, V3, V4

Variations - Generates 4 new variations based on the selected image.

Great for exploring different directions

Re-roll Button

Regenerates 4 new images using the same prompt.

Use when none of the results work

Web Button

Opens the image in your Midjourney gallery on the web.

Easier downloading and sharing

Pro Tip: After upscaling, you'll see additional options like "Vary (Strong)" and "Vary (Subtle)" for further refinement, plus pan and zoom controls.

Essential Parameters Reference

Parameters are added at the end of your prompt with "--" prefix. They control various aspects of generation:

Parameter Function Example
--ar Aspect ratio --ar 16:9, --ar 1:1, --ar 9:16
--v Midjourney version --v 6 (latest)
--stylize Artistic interpretation (0-1000) --stylize 750
--chaos Variation level (0-100) --chaos 50
--no Exclude elements --no text, people
--seed Reproducibility --seed 12345
--tile Seamless pattern --tile
--niji Anime style model --niji 6
--q Quality (.25, .5, 1) --q 1

Common Parameter Combinations

Widescreen landscape:

--ar 16:9 --v 6 --stylize 500

Instagram post:

--ar 1:1 --v 6 --stylize 250

Phone wallpaper:

--ar 9:16 --v 6

Anime character:

--niji 6 --ar 3:4

Crafting Effective Prompts

Well-structured prompts consistently produce better results. Follow this framework:

Prompt Structure Formula

[Subject] + [Environment/Setting] + [Style] + [Lighting/Mood] + [Technical Details] + [Parameters]

Example breakdown:

  • Subject: a majestic wolf
  • Setting: standing on a snowy mountain peak
  • Style: realistic digital painting
  • Mood: dramatic lighting, golden hour
  • Technical: highly detailed, 8k resolution
  • Parameters: --ar 16:9 --v 6

Full prompt:

a majestic wolf standing on a snowy mountain peak, realistic digital painting, dramatic lighting, golden hour, highly detailed, 8k resolution --ar 16:9 --v 6

Advanced Techniques

1. Image Reference (Image Prompting)

Use existing images as reference for style or composition.

How: Paste image URL before your text prompt

[image URL] a cat in similar style, vibrant colors --v 6

The image URL must be publicly accessible.

2. Multi-Prompts with Weights

Control the influence of different elements using "::" separator.

sunset::2 ocean::1 mountains::0.5 --v 6

Higher numbers = more emphasis. Sunset is twice as prominent as ocean.

3. Negative Prompting

Exclude unwanted elements from your generations.

beautiful landscape, peaceful --no people, buildings, text, watermark

4. Using Seeds for Consistency

The --seed parameter allows you to reproduce similar results.

1. Generate an image you like

2. React with envelope emoji to get the seed number

3. Use that seed with modified prompts for variations

same prompt with changes --seed 123456

5. Pan and Zoom

Extend your images beyond their original borders after upscaling.

  • * Arrow buttons: Pan in that direction to extend the image
  • * Zoom Out buttons: Add more environment around the subject
  • * Custom Zoom: Type specific dimensions or additions

Common Mistakes to Avoid

Mistake 1: Prompts Too Vague

"A nice picture" won't give you good results.

Solution:

Be specific about subject, style, lighting, and mood. "A golden retriever puppy playing in autumn leaves, warm sunlight, photograph, shallow depth of field"

Mistake 2: Forgetting Aspect Ratio

Default is 1:1, which may not suit your needs.

Solution:

Always specify --ar for your use case. 16:9 for YouTube, 9:16 for mobile, 1:1 for social media.

Mistake 3: Wasting Generations

Excessive trial-and-error burns through your monthly quota.

Solution:

Plan your prompts. Save effective templates. Use Standard plan's Relax mode for experimentation.

Mistake 4: Ignoring Versions

Different versions have different strengths.

Solution:

Use --v 6 for best overall quality. Try --niji 6 for anime. Check settings regularly as new versions release.

Efficient Workflow Tips

1

Create a Prompt Library

Save your best prompts in a document. Organize by style/purpose. Modify proven prompts rather than starting from scratch.

2

Use a Private Server

Invite the Midjourney bot to your own Discord server for a cleaner workspace and easier image management.

3

Batch Similar Requests

When creating content for a project, generate all related images together. Helps maintain consistent style.

4

Learn from Others

Browse the Midjourney community. Use /describe on images you like to reverse-engineer effective prompts.

Summary

Quick Reference

  • * /imagine - Main generation command
  • * U1-U4 - Upscale images
  • * V1-V4 - Create variations
  • * --ar - Set aspect ratio
  • * --v 6 - Use latest version
  • * --no - Exclude elements
  • * Structure prompts - Subject + Setting + Style + Mood + Quality

Practice these techniques consistently, and you'll be creating professional-quality AI images in no time. Remember: specificity and structure are key to great results.
