About a week ago, Midjourney released a style tuner.
Even though we call it a "style" it's a bit more than that, it's really controlling the "personality" of the model and it influences everything from colors to character details.
In other words, it guides the aesthetic style of the images it generates. Here's a style I made: 1VUR9cU9PM0Cj. Images generated with it generally fit a vague gouache-style, sort of like a more opaque watercolor. It definitely leans towards bright colors and clouds.
All of the following prompts used the title with
--style 1VUR9cU9PM0Cj. Perhaps you'll recognize some of these from previous posts.
quirky underground comic style illustration, pen and ink and watercolor and collage in the style of Marc Bell, bathing cats, bath house onsen cats
I generated each of the following using the prompt
game console --style <title>.
With just a few examples to work with, to me Midjourney seems to make images that better fit the style with shorter prompts. I'll have to see in a future post how much the
--stylize parameter enforces the given style with longer prompts.
