Ready to make the most of Midjourney's V7? This guide will help you craft better prompts and troubleshoot common issues. We'll explore how Midjourney interprets your words, and how to get the best results.
Getting Started with Midjourney Prompts
Let's begin with the basics. It's important to know how to ask questions and interact effectively. Midjourney is a powerful tool, and understanding its inner workings will greatly improve your creations.
Warm-up: Engaging with the Community
Jump into the chat! Say hi, share your favorite color, or mention any technical issues you're facing. Active participation is key to learning and growing within the Midjourney community.
The Allure of Midjourney: A Creative Binge?
Have you ever found yourself lost in Midjourney for hours? It's easy to get hooked on bringing your imagination to life. The platform's accessibility makes it tempting to spend hours crafting image after image.
Midjourney might also boost your awareness. Immersing yourself in visual detail could make you more sensitive to colors, textures, and shapes in everyday life.
You might even find yourself framing scenes in your mind like potential prompts. It's a sign that your brain is adapting to this new creative outlet.
Understanding How Midjourney Works
To get the most out of Midjourney, it helps to know what's happening behind the scenes. Let's break down the process and how it affects your prompts.
The Diffusion Process Explained
Midjourney uses something called "diffusion." During its training, Midjourney learned how pixel patterns correspond to words. It matched millions of images with descriptive text, building rules about these relationships.
When you enter a prompt, Midjourney uses those rules to refine an image, adjusting pixels in waves. This process, called denoising, starts with random visual noise known as a seed.
Midjourney never starts from a blank canvas. It either begins with a seed of random noise or refines an existing image. This is why variations and remixes can fix issues with faces or fingers, as Midjourney is building upon something already there.
The Seed: A Starting Point
A seed is like television static – a field of chaotic pixels. Midjourney transforms this chaos into an image based on your prompt. Although the idea of using the same seed for consistent results is appealing, its impact is limited because each job is assigned to a random GPU, making it hard to maintain long-term consistency. Seeds are most useful for testing prompts quickly.
Prompt Optimization: Making the Most of Your Time
Ideally, Midjourney refines the seed until it plateaus, meaning there are no more meaningful changes. But in reality, processing time is limited. That’s why optimizing your prompts matters. Midjourney shows an abbreviated version of this denoising process in its progress videos. The transformations happen quickly, so efficient prompts are essential.
Controlling the Canvas: Anchoring the Details
If you don't control something in your prompt, Midjourney will fill in the gaps using its best guess. This means trying to control all the details you care about to keep them on the canvas. "No lazy prompting" is a good reminder to make an effort.
Each prompt is a timed job. If it takes too long, the AI may start blending or dropping details, leading to incoherence. In V7, this is less of a concern due to improved efficiency, but it's still good to have optimization tricks ready.
Avoid chaotic tokens like conversational instructions in standard prompts. Also, prompts that read like a novel will dilute your results. Grammar and punctuation matter because Midjourney analyzes the structure of your prompt.
Instead of a jumbled list of words, use clear sentences to guide Midjourney. For example, instead of "sunset crime eagle city cyberpunk," try "a cyberpunk eagle perched on a rooftop, neon city lights glowing at sunset." Clarity and specificity are key.
If you don't take control, Midjourney will make choices for you, leading to unexpected results. So before diving into troubleshooting, it's good to understand how Midjourney works.

Questions and Answers on Controlling the Canvas
Someone asked, "Can you make a 4x4 grid like a step-by-step image, each step being an image of some process?" While this is possible with specific prompting, it's better to wait for the omni reference feature. Midjourney is passive and paints what you tell it to, so detailed instructions are necessary.
Three Key Elements: Style, Subject, and Background
[P]A good approach to prompting is to consider three things:
How should it look (style)?
What's in the image (subject)?
Where is it (background)?
If you miss one, Midjourney fills in the blanks with the most predictable option. If you say "wizard," expect a Gandalf-like figure unless you provide more specifics.[/P]
For example, "a flat cartoon depicting an orange sailboat on a teal sea at night" includes the subject (sailboat), background (teal sea at night), and style (flat cartoon).
Leveraging Compound Subjects
Use compound subjects to add more details without consuming processing time. Instead of describing multiple ships, use "an armada." Instead of listing people, use "family" or "funeral." These archetypes give you more on the canvas efficiently.
For example, instead of describing a man, woman, and child on a blanket with a basket of food, simply use "family picnic."
Backgrounds also matter. If you don't specify one, Midjourney will make it up. A backdrop could be "a forest clearing" or "a neon-lit alley." A context could be "stands in line at the bank," which invokes many details without needing extensive descriptions.
Optimizing Your Prompts: Archetypes and Efficiency
When your prompts lose details or show blending, it's time to optimize. One powerful method is using archetypes. An archetype is the dominant representation of something in Midjourney's dataset. You can either describe something yourself or invoke the archetype and let Midjourney fill in the stereotypical details.
Invoke vs. Describe: A Key Decision
For example, instead of describing a man with a beard, baseball cap, flannel shirt, and axe, you can simply say "a lumberjack." Using the word "lumberjack" and letting Midjourney supply the default details uses less processing time than describing the lumberjack yourself.
At the same time, you want to learn to avoid archetypes to control undesirable outcomes. Knowing when to describe versus invoke is an important part of prompting.
Breaking Archetypes: Avoiding Stereotypes
Consider a woman sitting in a cafe on a rainy day. You don't need to specify coffee, tables, or windows because "cafe" invokes these details. However, the archetype of a cafe is so strong that if you want to depict a woman in a cafe without coffee, you'll need to avoid using the word "cafe" altogether.
Instead, describe the scene in detail: "A woman sitting in a wooden chair at an empty round wooden table in front of a single-pane glass window looking out on the city sidewalk on a rainy day." This breaks the archetype and gives you more control.
Using Words Midjourney Understands: Avoiding Chaotic Tokens
[P]If your prompt contains chaotic tokens, you'll lose control of the canvas. Chaotic tokens are words and phrases that Midjourney can't easily translate into visuals. Examples include:]
Conversational instructions (unless in conversational mode)
Jargon
Abstract concepts
Instead of "a sorrowful night longing for home," try "a solitary knight wearing battered armor standing on a foggy battlefield in the dawn light." Use concrete, visual language with specific poses, settings, and atmospheres.
Guidelines for Clear and Visual Prompts
[P]When troubleshooting, follow these guidelines:
Remove conversational language
Use real sentences with correct grammar and punctuation
Use dense visual language
Remember, Midjourney standard mode is not an LLM and doesn't understand conversations, commands, or instructions. Also, Midjourney doesn't comply with technical specifications. While photographic terms are popular, they're not always reliable. It's better to use terms that correspond to iconic photographic aesthetics, like "Polaroid" or "Leica."
