Midjourney glossary

Plain-English definitions of the Midjourney terms and parameters creators use every day, plus the Dreamdrive features built around them.

Prompt

The text description Midjourney turns into images. A strong prompt names the subject, composition, style, lighting and environment, followed by any parameters.

Parameter

An option added to the end of a Midjourney prompt, written with two dashes, such as --ar 16:9. Parameters change how an image is generated without changing the description.

Aspect ratio (--ar)

The width-to-height ratio of the image, for example --ar 16:9 for widescreen or --ar 4:5 for an Instagram portrait post.

Stylize (--stylize, --s)

Controls how strongly Midjourney applies its own default aesthetic. Low values follow your words more literally; high values are more artistic.

Chaos (--chaos, --c)

Controls how different the images in a single grid are from one another. Higher chaos gives more varied, less predictable results.

Weird (--weird, --w)

Pushes results toward unusual, unconventional aesthetics. Useful for experimental looks.

Seed (--seed)

The number Midjourney uses as the starting point for an image. Reusing a seed with the same prompt and settings gives more repeatable results.

No (--no)

A negative prompt: tells Midjourney what to leave out, for example --no text, watermark.

Style raw (--style raw)

Reduces Midjourney's default beautification so results follow the prompt more literally. Popular for photography and precise art direction.

Style reference (--sref)

Transfers the visual style of a reference image or style code (colour, texture, lighting, mood) to a new image without copying its content.

Style code

A number used with --sref, such as --sref 2980181076, that stands for a particular look. Style codes are easy to save, share and reuse for consistent series.

Style weight (--sw)

Sets how strongly a --sref style reference influences the image. Lower is subtle; higher pushes the image closer to the reference style.

Image prompt

An image URL placed at the start of a prompt. Unlike --sref, an image prompt influences both the content and the style of the result.

Image weight (--iw)

Sets how much an image prompt matters relative to the text prompt.

Version (--v)

Chooses which Midjourney model version generates the image. Results, parameter ranges and style codes can differ between versions.

Niji (--niji)

A Midjourney model tuned for anime and illustrative styles.

Tile (--tile)

Generates images that repeat seamlessly, for patterns, textures and wallpapers.

Personalization (--p)

Applies your personal aesthetic, which Midjourney learns from images you rate or like, to a prompt.

Upscale

Increases an image's resolution and detail after generation.

Vary (Subtle / Strong)

Creates new variations of an existing image, either close to the original (Subtle) or more different (Strong).

Dreamtune

Dreamdrive's prompt builder. It turns a rough idea plus dropdown choices (composition, subject, reference, technical, style, environment) into a complete Midjourney prompt.

My Prompts

Dreamdrive's prompt library. It saves every prompt automatically into project folders that you can search and reuse with one click.

Style Vault

Dreamdrive's style library. It stores your --sref style codes with preview images and includes 1,000+ curated styles.

Credit (Dreamdrive)
