Concept LoRA to strengthen and improve darkness of images. It will also improve images with better directional lighting if you prompt specific light source. Composition of image should stay the same.

This concept also stabilises image and controls amount light sources. (usually you get one candle not 5 randomly placed)

LoRA weirdly enough works a little bit like slider, the higher weight the stronger darkness will be without changing composition much.

Use dark to make image with none or little light from light source.

Use dim lighting and type of lighting to make light coming from of the light source

You can mix both for stronger effect

Please avoid using too many LoRAs as the effect will weaken. (will still darken the image but not as much)

Still testing as some tags might add unusual amount of brightness

Notes from testing :

keeping prompt short gives best result (up to 75 tokens)

very dark - will trigger very dark skin tag

night is usually brighter than standard dark environment

sometimes brightness is tied to a seed so you might want to change it

usage of colours affects darkness greatly, try to think what colour would look like in darkness, or add dark to every colour you can, for example dark blue eyes, dark pink dress, dark green hair

shiny skin is an unrealistic common problem with a lot of models, adding it to negatives will shade skin better (shinny skin in darkness is just silly unless oiled up, sweaty or wet...)

overly unnecessary negatives will destroy darkness, keep it simple and work out from there

forge/a1111 adetailer is not working too well with his LoRA and it causes brighter box...on almost all my preview images..., if anyone know solution or good settings I would really appreciate any info (currently grabbed different detector that focuses more on face itself than box)
At the moment I can recommend some settings, not perfect but helps a little with blending,

Mask Blur : 20 Masked Padding : 128

Different VAE can help with that issue especially ones that do contrast

LoRA weight : 0.1-1

Main trigger :

dark

dim lighting

dark background

Secondary triggers:

dark [colour] - will make better shading for example : dark blonde hair, dark green eyes,dark pink lingerie

night

glowing

darkness - will make image darker but it's also tag for "dark magic" so you can expect a lot of shadowy stuff)

any light source to use with dim lighting, for example :

    lamp

    phone

    torch

    moon

    glowing eyes

    pryokinesis (fireball)

silhouette

shaded face

shadow

backlighting

underlighting

sidelighting

Recommended negatives :

Depends on need :

backlighting

underlighting

sidelighting

glowing [X] (hair etc.) - glowing tag can cause too much stuff to glow

shiny skin (will shade skin better)

and anything else that gets in a way
