Must useful commands for Midjourney
--iw. In Midjourney, you can load pictures as a reference. You can specify its "weight" - the bigger it is, the more it affects the result. The default value is 1.
--ar. A quick command for the aspect ratio, or "aspect ratio" parameter. By default, images are generated in 1:1 ratio, but this can be changed to 3:2 or 16:9, for example.
--s. Stylization level. A rather abstract parameter that can be set from 0 to 60,000.
--q. Quality level. By default it is set to 1, you can set it to 2, then there will be more details in the picture. There used to be a maximum parameter of 5, but it was removed due to high load.
