This is a dark and moody style that backlights subjects so their features are obscured in shadows. Most images have a lot of grain to give an appearance of low-light or vintage photography.
This one varies a lot between subjects so you may have to experiment with the weights to get the look you want. When it's very strong, it can make the subject appear as a silhouette. When it's weaker it can simply look like black and white photography.
Its bias toward monochrome images is strong, but you can add colors to many subjects by prompting for them.
