MidJourney is one of the most powerful AI tools for generating images, particularly useful for architects and designers who want to quickly and accurately visualize design ideas. However, to get the best results from MidJourney, it’s important to understand and master the specific parameters and commands the AI offers. This guide provides a clear and simple explanation of all MidJourney commands and parameters, optimized for freelance architects and architectural firms.
Introduction to MidJourney parameters
In MidJourney, parameters are additional commands that can be added at the end of a prompt to influence the final appearance of the generated image. These parameters allow you to control elements such as image quality, aspect ratio, the level of stylization, and more.
Each parameter is preceded by two dashes (–), followed by the parameter name and an optional value. For example: –ar 16:9 sets the aspect ratio to 16:9.
Main MidJourney parameters
Aspect Ratio (–ar)
The –ar parameter lets you specify the image’s aspect ratio, determining whether the output is rectangular or square.
Syntax: –ar :
Example: –ar 16:9 creates a widescreen image.
Practical use: In architectural visualization, a 16:9 aspect ratio is ideal for panoramic views of buildings, while a 1:1 ratio can be useful for specific details.
Image Quality (–q)
The –q parameter adjusts the quality of the generated image, affecting rendering time and resource usage.
Syntax: –q where the value can be 0.25, 0.5, 1, 2 (default is 1).
Example: –q 2 produces the highest quality image but requires more time and resources.
Practical use: For high-resolution presentations, use –q 2, while for quick sketches, –q 0.5 may suffice.
Stylize (–stylize)
The –stylize parameter controls how much the AI applies its default style to the generated image. Higher values make the image more stylized and artistic.
Syntax: –stylize with typical values ranging from 0 to 1000.
Example: –stylize 500 applies a moderate level of stylization.
Practical use: This parameter is useful for creating more artistic and conceptual images, which can inspire clients or explore new design concepts.
Chaos (–chaos)
The –chaos parameter introduces variability and creativity into the generated images. Higher values produce less predictable and more creative results.
Syntax: –chaos with a range from 0 to 100.
Example: –chaos 75 increases the AI’s creativity, producing unexpected results.
Practical use: Using –chaos can be helpful during brainstorming to explore unconventional and out-of-the-box ideas.
Image Weight (–iw)
The –iw (Image Weight) parameter lets you balance the influence of a reference image against the prompt text.
Syntax: –iw with typical values from 0.5 to 2.
Example: –iw 1.5 gives more weight to the reference image than to the text.
Practical use: When using an image of a previous project as a reference, the –iw parameter can help maintain the visual integrity of the original project.
Tile (–tile)
The –tile parameter generates images that can be used as seamless patterns, creating a continuous effect perfect for textures and surfaces.
Syntax: –tile
Example: –tile creates a seamless pattern usable for flooring, walls, or fabric textures.
Practical use: Ideal for creating patterns for surfaces in interior design or architectural facades.
Seed (–seed)
The –seed parameter allows you to reproduce exactly the same image generated earlier, using the same seed number.
Syntax: –seed with values from 0 to 4294967295.
Example: –seed 123456 ensures the result is the same as a previous generation.
Practical use: This is particularly useful when you want to replicate a specific image with minimal variations for further modifications or presentations.
Other Useful Commands in MidJourney
–no
The –no parameter is used to exclude unwanted elements from the image.
Syntax: –no
Example: –no people excludes people from the generated image.
Practical use: It can be useful to keep the image focused only on architectural elements, without distractions.
–v
The –v parameter indicates the version of the MidJourney algorithm to use.
Syntax: –v with numbers representing the different available versions.
Example: –v 5 uses the fifth version of the algorithm.
Practical use: Choosing the version can influence the style and quality of the generated image.
Creating complex prompts with multiple parameters
MidJourney allows combining multiple parameters in a single prompt to achieve highly specific results. For example, a prompt that combines several parameters could be:
A modern commercial building with a glass facade, in a crowded urban area, at sunset --ar 16:9 --q 2 --stylize 750 --chaos 30
This prompt will generate a high-quality panoramic image, stylized for an artistic effect with an extra touch of creativity. Here it is:
It’s important that the sequence of parameters follows a priority logic based on what is most important for the desired image. For example, if quality is crucial, the –q parameter should be included first.
Common mistakes to avoid
Even though using parameters can greatly improve the quality of images, it’s easy to make mistakes that can lead to undesirable results.
Parameter overload
Using too many complex parameters at once can confuse the AI, resulting in a less coherent image. Focus on essential parameters and experiment with one or two additional parameters at a time.
Inconsistency between parameters and prompt
Ensure that the parameters are consistent with the theme and description of the prompt. For example, a prompt requesting a night scene should not include parameters for daylight lighting.
Experimentation and iteration
MidJourney is a powerful tool that rewards experimentation. Don’t hesitate to tweak and iterate on your prompts to explore different possibilities and get the most out of the images generated.
Testing Variations
Try generating multiple versions of an image by slightly modifying the parameters to see how the results change.
Comparing Results
Save different versions of the generated images to compare them and understand which parameters work best for your specific projects.
