V67 Film Noir – LoRA for Flux and Krea 2. Professional Film Noir Style, Classic 1940s Cinematic Moods.

Premise: If you decide to use my model, I will give you 500 Yellow Buzz if your image is chosen for the cover of CIVITAI – even if used in combination with other models.

R+ images will be hidden from the gallery. LoRA model trained with Flux and Krea 2.

Putting a Like to the V67 models is worth more than giving me Buzz (yellow/green).

Credits & Notes

V67 Film Noir is inspired by the classic films of the 1940s and 1950s, the cinematography of John Alton, Nicholas Musuraca, and Gregg Toland, and the hard‑boiled fiction of Dashiell Hammett, Raymond Chandler, and James M. Cain. This LoRA lets you bring that language to Flux – from subtle shadow play to bold noir statements.

“The noir hero is a knight in blood‑caked armor. He’s dirty and he does his best to deny the fact that he’s a hero the whole time.” – Frank Miller
