This is a dark moody style with atmospheric effects. Images are grainy and most scenes have atmospheric particles and a thick fog in the background. Images tend to have a cold abandoned feeling and lean toward a horror aesthetic. If you're looking for something more warm and cozy, check out my other "Moody Photography" style.
The trigger is "n0vuschr0ma style". You can also try adding "moody photography" or "dreamy photography" to influence the style's look. This style is borderline between a photography and painting style, and can be pushed either way by adjusting the prompt and weight.
