25.05.02 - New Feature You Should Know: A Complete Guide to Midjourney v7's "--exp" Parameter
Since releasing v7, Midjourney has made various changes to its algorithm, with new updates arriving almost every week since then. Today, they finally announced a new parameter called "--exp." This experimental feature allows you to adjust the aesthetic elements of an image, enabling more detailed and creative image generation.

What is the "--exp" Parameter?
Since the release of Midjourney v7, the algorithm has undergone various changes, with new updates arriving almost every week since then. Today, a new parameter called "--exp" has finally been announced. This is an experimental feature that allows you to adjust the aesthetic elements of an image, enabling more detailed and creative image generation.
Features of the "--exp" Parameter
- Value range: 0 to 100 (default is 0)
- Similar to the "--stylize" parameter, but allows for more detailed expression
- Makes images more dynamic and creative, and enhances tone mapping effects
- Using higher values reduces prompt accuracy and decreases image diversity
Recommended Usage
For practical use, we recommend primarily using the following values: 5, 10, 25, 50, and 100.
You'll notice significant changes especially between 5 and 50, but the difference between 50 and 100 is less pronounced.
Combining with Other Parameters
Using very high values (25–50 or above) may overwhelm the effects of the "--stylize" or "--p" parameters. When combining with other parameters, we recommend using lower values.
Example Comparison
To compare the differences this time, we'll look at a comparison between the normal mode (no parameters), profile (--p) mode (using a --p number that only I, as an individual user, have), and profile + --exp parameter combined.
This time, let's use a cel-shaded anime prompt!
--exp 0 (Default)
Prompt:A vampire girl sitting in a candlelit manor, cel of anime flat shading, deep reds and blacks, detailed patterned clothing --v 7

--exp 5
Prompt:An astronaut floating in zero gravity adjusting his helmet, cel anime line art with inked outlines, floating objects around, style abstract layout --ar 4:3 --exp 5 --raw --stylize 900

--exp 25
Prompt:A determined idol girl performing on an outdoor stage in the rain, cel of anime watercolor texture, glowing stage lights bleeding into puddles, soaked hair clinging to her face, powerful expression of passion

--exp 50
Prompt:A sleek black cat walking alone through a forest path covered in fallen leaves, golden autumn tones blending into dark fur, gentle shadows underfoot, peaceful rural atmosphere --ar 4:3 --exp 50 --raw --stylize 900 --v 7

--exp 100
Prompt:A sleek black luxury sedan driving along an empty coastal road at golden hour, cinematic lighting, glossy paint reflecting warm sky, ocean cliffs in the background, ultra-detailed textures, wide-angle lens, studio-quality render --ar 16:9 --exp 100 --raw --stylize 900 --v 7

Comparing All --exp Values
Prompt:A stylish Japanese teen walking down Takeshita Street in Tokyo. Wears a deconstructed denim jacket layered over a graphic crop top, baggy cargo pants, chunky sneakers, and a bucket hat. Oversized headphones around neck, messenger bag slung across chest. Vibrant graffiti walls and quirky shops fill the background. Daylight with dynamic shadows and authentic urban texture.
