Prompt
Close-up portrait of a woman looking directly at the camera. Her face and neck are mostly obscured by deep shadow. A single, narrow horizontal band of light cuts across her face, illuminating only her eyes and the bridge of his nose. He has a strong, defined jawline and short, textured hair. She is wearing a simple black shirt. The background is a plain, overcast grayish-blue sky. Dramatic, high-contrast lighting creates a moody, cinematic atmosphere.

node (ComfyUI-Krea2-Ostris-Edit), which lets Krea 2 edit images despite being a text-to-image model. It is experimental: Krea 2 is not an edit model, so expect less precision than dedicated editors, occasional changes to the image, slight lighting and color shifts and possible issues with horizontal aspect ratios.
Trigger: enhance this image. The author's prompt: Enhance this image to high resolution with rich fine details. Sharpen all textures and surfaces, add microdetail...
