Midjourney
You’ve seen those breathtaking AI-generated images on social media — fantastical landscapes, photorealistic portraits, concept art that looks like it belongs in a movie. Chances are, many of them were made with Midjourney.
Midjourney is widely regarded as the gold standard for AI image generation. Its output quality is consistently stunning, with a distinctive aesthetic that other tools struggle to match. Professional designers, marketers, game developers, and hobbyists all use it to create visuals that would have required hours of skilled work just a few years ago.
But getting started can feel intimidating. What prompts should you write? What do all those parameters mean? How do you go from a vague idea to a polished image?
This guide answers all of that. By the end, you’ll know how to set up Midjourney, write effective prompts, use advanced parameters, and create images that genuinely impress.
What Is Midjourney?
Midjourney is an AI image generation service created by Midjourney, Inc., an independent research lab founded by David Holz (co-founder of Leap Motion). The service takes text descriptions — called “prompts” — and turns them into images.
What sets Midjourney apart from competitors like DALL-E and Stable Diffusion:
- Aesthetic quality: Midjourney images tend to be more visually polished and artistically coherent
- Style consistency: It produces a recognizable “Midjourney look” — atmospheric, detailed, and often painterly
- Community: A massive Discord community where millions of users share prompts and learn from each other
- Rapid improvement: Each version (currently V6.1) has brought dramatic quality improvements
How It Works (Simplified)
- You write a text description of the image you want
- Midjourney’s AI model interprets your words
- The model generates four image variations
- You pick the one you like best and can upscale or create variations
The AI has been trained on billions of images and has learned the relationships between words and visual concepts. When you type “a cozy cabin in the mountains at sunset,” it doesn’t search for existing images — it creates entirely new ones based on its understanding of what those words mean visually.
Midjourney Pricing Plans
All Midjourney plans require a paid subscription. Here’s what each tier offers:
| Plan | Price | Fast GPU Time | Relaxed Generations | Key Features |
|---|---|---|---|---|
| Basic | $10/month | ~3.3 hours (~200 images) | None | Basic access, commercial rights |
| Standard | $30/month | 15 hours (~900 images) | Unlimited | Stealth mode option |
| Pro | $60/month | 30 hours | Unlimited | Stealth mode, 12 concurrent jobs |
| Mega | $120/month | 60 hours | Unlimited | Maximum speed and concurrency |
Annual billing saves roughly 20% on all plans.
Which Plan Should You Choose?
- Basic ($10/month): Perfect for beginners and casual users. 200 images per month is enough to learn the system and create occasional images.
- Standard ($30/month): Best value for regular users. The unlimited relaxed generations mean you’ll never run out, and 15 hours of fast time covers most active use.
- Pro ($60/month): For professionals who need high volume, concurrent jobs, and stealth mode (your images won’t appear in the public gallery).
Start with Basic, upgrade to Standard if you find yourself wanting more.
Understanding Fast vs. Relaxed Mode
- Fast mode: Your images generate in about 30-60 seconds. Uses your allocated GPU time.
- Relaxed mode (Standard and above): Images go into a queue and generate in 1-10 minutes. Doesn’t use your fast time — truly unlimited.
For learning and experimentation, relaxed mode is perfectly fine. Use fast mode when you need results quickly.
Getting Started: Setup Guide
Method 1: Web Interface (Recommended for Beginners)
The easiest way to use Midjourney in 2026 is through the web interface:
- Go to midjourney.com
- Sign in with your Discord account or create a new Midjourney account
- Choose a subscription plan
- You’ll land on the creation page — start generating immediately
The web interface offers:
- A clean, intuitive image generation UI
- Your personal gallery of all generated images
- An explore page to see what others are creating
- Image editing tools (inpainting, outpainting, zoom)
Method 2: Discord
Midjourney’s original interface was Discord, and it’s still available:
- Go to discord.gg/midjourney and join the server
- Navigate to a #newbies channel
- Type
/imaginefollowed by your prompt - The bot will generate your images in the chat
Discord is great for:
- Community interaction and inspiration
- Seeing what others are creating in real time
- Getting feedback on your work
- Learning prompt techniques from experienced users
For this guide, we’ll focus on the web interface since it’s more beginner-friendly.
Writing Your First Prompt
The prompt is everything in Midjourney. It’s the text description that tells the AI what to create. Let’s start simple and build up.
Your Very First Image
Type something straightforward:
a golden retriever puppy playing in autumn leaves
Midjourney will generate four variations. You’ll notice that even with this simple prompt, the results are impressively detailed and visually appealing.
Anatomy of a Good Prompt
A well-constructed Midjourney prompt typically follows this pattern:
[Subject] + [Environment/Setting] + [Style/Medium] + [Lighting] + [Mood/Atmosphere] + [Parameters]
Example:
a medieval knight standing on a cliff overlooking a vast kingdom, oil painting style, golden hour lighting, epic and majestic atmosphere --ar 16:9
Let’s break down each component.
Component 1: Subject
Be specific about your main subject. The more detail you provide, the more control you have:
- Vague: “a woman” → Too generic, unpredictable results
- Better: “a young woman with red hair and freckles” → More specific
- Best: “a young woman with flowing red hair and freckles, wearing a green velvet dress, holding a book” → Detailed control
Component 2: Environment/Setting
Where is your subject? What surrounds them?
- “in a dense bamboo forest”
- “in a futuristic Tokyo cityscape at night”
- “in a cozy library with floor-to-ceiling bookshelves”
- “floating in outer space with Earth in the background”
Component 3: Style/Medium
This dramatically changes the look of your image:
- Photographic: “photograph,” “DSLR photo,” “35mm film,” “macro photography”
- Artistic: “oil painting,” “watercolor,” “digital art,” “concept art”
- Specific styles: “Studio Ghibli style,” “art nouveau,” “cyberpunk,” “minimalist”
- Illustration: “children’s book illustration,” “comic book style,” “technical illustration”
Component 4: Lighting
Lighting transforms the mood:
- “golden hour lighting” — Warm, romantic
- “dramatic chiaroscuro lighting” — High contrast, moody
- “soft diffused lighting” — Gentle, flattering
- “neon lighting” — Cyberpunk, urban
- “backlit silhouette” — Dramatic, mysterious
- “studio lighting” — Clean, professional
Component 5: Mood/Atmosphere
Set the emotional tone:
- “serene and peaceful”
- “dark and foreboding”
- “whimsical and playful”
- “epic and grandiose”
- “intimate and cozy”
Essential Parameters
Parameters are commands you add to the end of your prompt (after --) that control technical aspects of the generation.
Aspect Ratio (—ar)
Controls the shape of your image:
| Parameter | Ratio | Best For |
|---|---|---|
--ar 1:1 | Square | Instagram, profile pictures |
--ar 16:9 | Widescreen | Desktop wallpapers, YouTube thumbnails |
--ar 9:16 | Tall/portrait | Phone wallpapers, Instagram Stories |
--ar 3:2 | Classic photo | General photography |
--ar 21:9 | Ultra-wide | Cinematic, banner images |
--ar 4:5 | Portrait | Instagram posts |
Example:
a mountain landscape at sunrise --ar 16:9
Stylize (—s)
Controls how strongly Midjourney applies its aesthetic style:
--s 0— Minimal styling, follows prompt more literally--s 100— Default balance--s 250— Medium artistic interpretation--s 750— Maximum artistic flair (Midjourney takes more creative liberty)
Low stylize is better for specific, controlled outputs. High stylize is better when you want Midjourney to “do its thing” and create something beautiful.
Chaos (—c)
Controls variation between the four generated images:
--c 0— All four images look similar--c 50— Moderate variation--c 100— Maximum variation (each image is wildly different)
Use high chaos when exploring ideas, low chaos when you know what you want.
Quality (—q)
Controls rendering quality and generation time:
--q .25— Fastest, lowest quality (good for testing ideas)--q .5— Balanced--q 1— Default quality--q 2— Highest quality (uses more GPU time)
Negative Prompting (—no)
Exclude specific elements:
a beautiful garden --no people, text, watermark
This tells Midjourney to avoid including people, text, or watermarks in the image.
Prompt Writing Techniques
Technique 1: The Photography Approach
Write prompts as if you’re describing a photograph:
portrait photo of an elderly Japanese fisherman, weathered face with deep wrinkles, wearing a traditional straw hat, early morning fog on a lake, shot on Hasselblad, natural lighting, shallow depth of field, film grain
Photography terms Midjourney understands:
- Camera types: Hasselblad, Leica, Canon 5D
- Lens types: 85mm, wide-angle, macro, telephoto
- Film stocks: Kodak Portra, Fujifilm
- Techniques: bokeh, long exposure, tilt-shift, HDR
Technique 2: The Art Direction Approach
Direct the image as if you’re an art director:
concept art of an underwater city, bioluminescent architecture, art nouveau style, deep ocean blue and teal color palette, ray tracing, highly detailed, cinematic composition
Technique 3: The Remix Approach
Combine unexpected elements for unique results:
a cat wearing a space suit floating through a galaxy made of flowers, by Hayao Miyazaki, whimsical, detailed, vibrant colors
Technique 4: The Minimalist Approach
Sometimes less is more:
solitude --ar 16:9 --s 750
Abstract or single-word prompts with high stylize values let Midjourney’s creativity shine.
Technique 5: The Reference Artist Approach
Reference artistic styles (not specific living artists, to be respectful):
a mystical forest, in the style of art nouveau, similar to Alphonse Mucha, ornate borders, flowing organic lines, rich jewel tones
Working with Your Generated Images
The Image Grid
When Midjourney generates images, you get four variations in a 2x2 grid. From here you have several options:
U1, U2, U3, U4 — Upscale: Select one image to generate a high-resolution version
V1, V2, V3, V4 — Variations: Generate four new variations based on one specific image
Re-roll — Generate four completely new images with the same prompt
Upscaling
When you upscale an image, you get a higher-resolution version. From the upscaled image, you can:
- Vary (Subtle): Create variations with small changes
- Vary (Strong): Create variations with more significant changes
- Zoom Out: Expand the image canvas (adds content around the edges)
- Pan: Extend the image in a specific direction
- Vary (Region): Select a specific area to regenerate (inpainting)
Inpainting (Vary Region)
This powerful feature lets you select a specific area of an image and regenerate just that portion:
- Upscale an image
- Click “Vary (Region)”
- Use the selection tool to mark the area you want to change
- Type a new prompt for just that region
- Midjourney regenerates only the selected area
Use cases:
- Fix a hand that looks weird
- Change a character’s clothing
- Add or remove objects
- Modify the background while keeping the subject
Outpainting (Zoom Out)
Zoom out to see more of the scene:
- Upscale an image
- Click “Zoom Out 1.5x” or “Zoom Out 2x”
- Midjourney imagines what exists beyond the original frame
This is great for turning a portrait into a full scene or revealing more of a landscape.
Style Guide: Getting the Look You Want
Photorealistic Images

dramatic shadows, moody, cinematic noir
Key terms: “dark,” “moody,” “dramatic,” “noir,” “chiaroscuro,” “low-key lighting”
Common Mistakes and How to Fix Them
Mistake 1: Prompts That Are Too Long
Midjourney doesn’t read every word equally. Front-loaded words carry more weight. A 200-word prompt often produces worse results than a focused 30-word prompt.
Too long: (Paragraph describing every tiny detail)
Better: Focus on the 5-6 most important elements and let Midjourney fill in the rest.
Mistake 2: Conflicting Instructions
“A bright sunny day with dramatic dark shadows and soft pastel colors and bold neon highlights” — these elements conflict with each other. Pick a coherent visual direction.
Mistake 3: Expecting Text in Images
Midjourney struggles with text. If your image needs text (like a book cover or poster), generate the image in Midjourney and add text using a design tool like Canva or Photoshop.
Mistake 4: Not Using Aspect Ratios
The default square (1:1) format isn’t always best. Think about where your image will be used and set the aspect ratio accordingly.
Mistake 5: Giving Up After One Try
The best Midjourney users iterate constantly. Generate, evaluate, adjust the prompt, regenerate. Use variations and remixing to progressively refine your vision. A single prompt rarely produces the perfect image on the first attempt.
Commercial Use: What You Need to Know
Your Rights as a Paid Subscriber
On any paid plan, you have broad commercial rights to the images you create. You can:
- Use them in marketing materials and advertisements
- Include them in products you sell
- Post them on social media for business purposes
- Use them in presentations and reports
- Include them in books, articles, and publications
Important Restrictions
- Revenue threshold: Companies with more than $1 million in annual gross revenue need at least the Pro plan
- No trademark creation: You can’t trademark a Midjourney image itself
- Terms may change: Always check the current terms of service
- Not exclusive: Other users could potentially create similar images
Best Practices for Commercial Use
- Keep records of your prompts and generation dates
- Don’t rely on AI art for your core brand identity (logo, etc.)
- Consider using generated images as starting points and editing them further
- Be transparent about AI usage where appropriate
- Stay updated on evolving copyright law regarding AI-generated images
Building a Workflow

Your First Week with Midjourney
Day 1: Simple Prompts Generate 20 images using basic prompts. Focus on subjects you like — animals, landscapes, portraits, food, architecture. Don’t worry about parameters yet.
Day 2: Add Style and Lighting Take your favorite prompt from Day 1 and try it with different styles (oil painting, photograph, anime, concept art) and lighting conditions.
Day 3: Learn Parameters
Experiment with --ar, --s, and --c. Try the same prompt with different parameter combinations.
Day 4: Advanced Prompting Practice the photography and art direction approaches. Use specific camera models, art styles, and composition terms.
Day 5: Refining Images Focus on variations, upscaling, inpainting, and outpainting. Take one good image and refine it into a great one.
Day 6: Build a Style Develop a consistent visual style using repeated prompt elements. Create a series of 5 images that look like they belong together.
Day 7: Create Something Real Generate images for a real project — a social media post, a blog header, a gift for someone, or a phone wallpaper. Apply everything you’ve learned.
Final Thoughts
Midjourney has democratized visual creation in a way that would have seemed impossible just a few years ago. Ideas that once required years of artistic training and expensive software can now be visualized in under a minute.
But here’s the thing most people miss: Midjourney is a skill. The difference between a beginner and an expert user is enormous — not because the tool is hard to use, but because effective prompt writing is a creative discipline in itself. The more you practice, the more control you gain over the output.
Start with simple prompts, experiment with parameters, study what works, and iterate relentlessly. Within a few weeks of regular practice, you’ll be creating images that genuinely surprise you with their quality.
The only way to learn is to generate. So open Midjourney, type your first prompt, and start creating.
よくある質問(FAQ)
Is there a free trial for Midjourney?
Midjourney occasionally offers limited free trials, but as of 2026, there is no permanent free tier. The Basic plan starts at $10/month, which gives you approximately 200 image generations. This is the most affordable way to get started.
Can I use Midjourney images commercially?
Yes, all paid Midjourney plans include commercial usage rights. You can use generated images for business purposes, marketing, products, and more.
