While Z-Image Base performs exceptionally well in general, low-key environments can expose occasional instability.

LKNR and LKWT are LoRAs created to reinforce structural and tonal stability in such low-light conditions, preserving form and presence without altering the base style.

LKWT: A low-key lighting LoRA that reproduces cinematic night interiors with controlled shadows and warm tungsten mood. The slight hint of dark scene will begin to give you warm tungsten low-key effect by the LoRA. (ek_lowkey_wint as a trigger word)

LKNR: This LoRA enhances clean rim lighting in low-key scenes, preserving facial structure and silhouette clarity even under extreme darkness and neon contrast. (ek_LKWT as a trigger word)

Euler A / Normal · Steps 20+ · CFG 3.5-6.5+ Usage: check the sample images.

Note:

• Prompt for dark space tends to place the subject smaller and lower in frame. Use “subject fills the frame” as needed.

• Strong keywords like “dark” and “lighting” or “high-key lighting” in negative affect the darkness drastically. Find the balance of your favorite.

• The lighting condition changes by adding various LoRAs. You need to adjust the prompt for the various situation.

• This is an early-stage project. LKNR and LKWT will continue to evolve as lighting-focused exploration progresses.
