LuminaBrush: Adding Lighting to Images with the Smart Paint Tool

General Introduction

LuminaBrush is an innovative interactive image editing tool for lighting effects, powered by artificial intelligence technology. The project uses a two-stage framework to process images: the first stage transforms the input image into a "uniformly illuminated" look, while the second stage generates lighting effects based on the user's doodles. This unique two-stage approach makes learning and applying lighting effects more intuitive and efficient. The project is based on Flux LuminaBrush not only adds lighting effects, but also independently removes existing lighting effects from an image using its Uniform Lighting feature, opening up even more possibilities for image editing.

Using Help

1. Quick start

1. Upload image: select the image file where the lighting effect is to be added
2. Waiting for pre-processing: the system will automatically convert the image to even lighting state
3. Drawing effects: Use the mouse or stylus to doodle on the image, specifying the areas where you want to add lighting effects.
4. Real-time preview: the system will display the effect after adding lighting effects in real time
5. Adjustment parameters: you can fine-tune the lighting effect by adjusting the parameters
6. Export results: download the processed image after satisfaction

2. Core functions in detail

2.1 Uniform lighting conversion

• This is the first stage of processing in LuminaBrush.
• Existing uneven lighting effects in images can be removed
• Generate a base image suitable for subsequent editing
• Supports standalone use of this feature

2.2 Drawing of lighting effects

• Specify lighting areas using simple doodle operations
• Supports multiple lighting effect styles
• Specific effects can be reproduced by setting a random seed (e.g. 12345)
• Real-time preview ensures results are as expected

3. Advanced techniques

3.1 Parameter adjustment

• Using random seeds to control the consistency of generated effects
• Adjustment of lighting intensity and range
• Fine tuning of color temperature and light distribution

3.2 Best practices

• It is recommended to test the effect on a small area first
• Different lighting effects can be stacked multiple times
• Save intermediate results for easy adjustment and modification
• Take care to maintain the natural feel and overall balance of the lighting effect

4. Cautions

• Processing large images may take more time
• Higher definition original images are recommended
• Ensure stable network connectivity
• Different monitors may affect the effect observation
• It is recommended that the results of the process be kept on a regular basis
