Midjourney is a powerful tool for creating stunning visuals from text prompts. To get the most out of it, understanding and using parameters is key. Parameters let you override default settings and fine-tune your images. This guide will cover essential Midjourney parameters to elevate your creative projects.
Understanding Midjourney Parameters
When you enter a text prompt into Midjourney, the system uses default settings to control aspects like aspect ratio and model version. Parameters are special commands that start with two dashes (--) followed by the parameter name (or abbreviation), a space, and the value. These parameters are always placed at the end of your prompt. For example:
“A futuristic cityscape --ar 3:4”
This command tells Midjourney to create an image of a futuristic cityscape with a 3:4 aspect ratio, overriding the default square format.
Key Midjourney Parameters
Version (--version or -v)
The version parameter specifies which Midjourney model to use for generating your images. Different models have unique aesthetics and prompt understanding capabilities. For example:
“A serene landscape --version 5” or “A vibrant portrait --v 5”
[P]Available versions include:</P]
1, 2, 3, 4, 5, 5.1, 6, 6.1
--test and --testp (intermediary models between V4 and V5)
--niji (anime-trained models)
Experimenting with different versions can yield fascinating results. Want to streamline your Midjourney experience? Check out the Midjourney Automation Suite from TitanXT to automate your prompts and variations.
Aspect Ratio (--aspect or -ar)
Aspect ratio defines the relationship between the width and height of your image, expressed as width:height. The default is 1:1 (square). To change it:
“A majestic mountain range --aspect 16:9” or “A detailed character portrait --ar 9:16”
Use whole numbers for aspect ratios. V6 models support aspect ratios up to approximately 14:1 or 1:14.
Chaos (--chaos or -c)
Chaos controls the diversity of results in your image grid. The default value is 0, and it ranges up to 100 (maximum diversity).
“An abstract painting --chaos 50” or “A minimalist design --c 20”
Increasing the chaos value introduces more variation in the generated images.
Stylize (--stylize or -s)
Stylize dictates the strength of Midjourney’s default visual aesthetic. The default is 100, with a range from 0 to 1000. Higher values produce more stylized results but may reduce prompt adherence.
“A vintage photograph --stylize 500” or “A modern illustration --s 800”
Style Reference (--style_reference or -sref)
Style reference allows you to apply aesthetic elements from reference images (color palettes, textures, styles) to your results. Use image URLs or sref codes:
“A portrait in the style of Van Gogh --style_reference van_gogh_image.jpg”
You can use multiple image URLs or the word “random” for a random style. Need help managing all those style references? The Midjourney Automation Suite from TitanXT can help you organize and automate your style workflows.
Style Weight (--style_weight or -sw)
Style weight controls the influence of the style reference on your results. The default is 100, and the range is 0 to 1000. Try lower values for a more subtle influence.
“A landscape with impressionistic style --style_reference monet_image.jpg --style_weight 50”
Style (--style)
The style parameter offers modes like “raw” to minimize Midjourney’s stylistic influence, useful for more photorealistic images. For example:
“A realistic portrait --style raw”
Quality (--quality or -q)
Quality determines how much time and power Midjourney spends generating your images. The default is 1. Lower values are faster but less detailed; higher values are slower but more detailed.
“A highly detailed landscape --quality 2” or “A quick sketch --q 0.5”
Speed: Turbo, Fast, Relax
These parameters control the image generation speed. Turbo and Fast use your fast GPU hours, while Relax does not (Relax is not available with all subscriptions).
“A vibrant abstract --turbo” or “A detailed illustration --fast”
Repeat (--repeat or -r)
Repeat runs the same prompt multiple times. Use it with Fast or Turbo mode.
“A cityscape at night --repeat 3” or “A portrait of a woman --r 2”
Video (--video)
Video creates a time-lapse of your initial image grid being generated. To use it, include --video in the prompt.
“A futuristic vehicle --video”
Stop (--stop)
Stop ends image generation early, taking values between 10 and 100. It’s useful for softer, more abstract results.
“An ethereal landscape --stop 50”
Image Weight (--iw)
Image weight controls the influence of images in your prompt. It’s used when you start your prompt with one or more image URLs. Takes decimal values between 0 and 3 in V6.
“image1.jpg image2.jpg A futuristic robot --iw 1.5”
Character Reference (--cref)
Character reference matches the character from a reference image. Paste the URL of your character reference image after --cref. Streamline your character creation with the Midjourney Automation Suite from TitanXT, designed to make complex tasks simple.
“A superhero in action --cref character.jpg”
Character Weight (--cw)
Character weight controls how closely Midjourney adheres to the clothing and hairstyle of your reference character. The default is 100, and the range is 0 to 100.
“A superhero in a new outfit --cref character.jpg --cw 0”
Personalize (--personalize or -p)
Personalize applies your custom Midjourney model to your results. You need to teach Midjourney about your style first.
“A landscape in my style --personalize” or “A portrait in my style --p”
No (--no)
No excludes specific elements from your image. Separate multiple items with commas.
“A forest landscape --no birds, insects”
Tile (--tile)
Tile creates repeating patterns. Just add --tile to your prompt.
“A geometric pattern --tile”
Seed (--seed)
Seed uses a specific seed number to initialize your image grid, ensuring similar results when you repeat the same prompt.
“A futuristic car --seed 1234”
Weird (--weird or -w)
Weird creates strange and unexpected results. The default is 0, and values range up to 3000.
“An alien landscape --weird 500”
Conclusion
Mastering Midjourney parameters opens up a world of creative possibilities. By understanding and experimenting with these settings, you can fine-tune your images to match your exact vision. Don't be afraid to try different combinations and values to discover what works best for your projects. Embrace the power of parameters and unlock your full creative potential with Midjourney.
