Luminabrush
Overview :
LuminaBrush is an interactive tool designed for drawing lighting effects on images. The tool employs a two-stage approach: the first stage converts the image to a 'uniform lighting' appearance, while the second stage generates lighting effects based on user doodles. This breakdown simplifies the learning process, avoiding the external constraints (like light transport consistency) that a single-stage approach might require. LuminaBrush constructs paired data to train the final interactive lighting sketch model by extracting 'uniform lighting' appearances from high-quality field images. Additionally, the tool can independently use the 'uniform lighting stage' to 'de-light' images, providing diverse visual effects.
Target Users :
The target audience consists of image processing professionals, designers, and enthusiasts who need to create or modify lighting effects on images to enhance visual appeal or for artistic creation. LuminaBrush offers an intuitive way to achieve these effects without requiring deep knowledge of complex lighting models.
Use Cases
Designers use LuminaBrush to add realistic lighting effects to product renderings.
Artists employ this tool in digital paintings to simulate different lighting conditions, enhancing the atmosphere of their works.
In movie poster design, LuminaBrush is used to adjust lighting to match the film's tone and style.
Features
? Two-stage framework: transforms the image into a uniform lighting appearance first, then generates lighting effects based on user input.
? User doodling support: allows users to guide the generation of lighting effects through doodling.
? Extraction of uniform lighting appearances from high-quality images: used for training the lighting sketch model.
? Independent use of the uniform lighting stage: to 'de-light' images, offering different visual effects.
? Flux model support: LuminaBrush is built on Flux, utilizing Flux LoRA for training.
? Hugging Face Demo available: users can experience a demo of LuminaBrush on Hugging Face.
? Suitable for various image types: capable of handling details like skin textures, hair, and fur.
