ComfyUI Relighting ic-light workflow #comfyui #iclight #workflow
TLDRIn this video, we explore ComfyUI's ic-light workflow, a powerful tool for adjusting lighting on objects while fine-tuning colors and shadows in relation to the background. The workflow is credited to lias, and the project is available on ComfyUI, thanks to Kaji. The video demonstrates how to use the tool with a demo and provides instructions on downloading necessary nodes and models. It discusses the importance of the mask in the process, offers tips on improving image quality and proportions, and explores the impact of the mask's position on lighting. The video also covers how to optimize the mask creation process and the effects of the blur radius and lighting description. Finally, it shows how to enhance the image with an IP adapter and the IC light conditioning feature, resulting in a harmonious and atmospheric final image. The tool is praised for adding control to the creative process.

- 💧 An example of creating an underwater scene for a model is given, highlighting the process of loading images and adjusting proportions.
- 🎭 The importance of a mask in the process is emphasized, as it plays a crucial role in the lighting and shadow effects.
- 📏 Adjusting the 'keep proportion' and 'pixels' settings can correct proportions but may affect image quality.
- 🖌️ The presenter suggests optimizing the mask creation process by allowing direct drawing on the image for more control.
- 🌟 Playing with the blur radius and the prompt description can significantly affect the final lighting and mood of the image.
- 🤖 An example of lighting a robot on a street at night is shown, demonstrating how to adjust the mask and use an IP adapter for background lighting.
- 🔄 Changing the transparency and blur radius can smooth out transitions between objects and their backgrounds.
- ✨ The IC light conditioning feature allows for fine-tuning of the lighting by adjusting the multiplier, similar to increasing contrast.
Q & A
What is the main purpose of the tool discussed in the video?
-The main purpose of the tool is to allow users to change the lighting on a certain object while adjusting colors and shadows, and considering the background and the project.
Who is credited with the development of this tool?
-The credit for the development of this tool goes to Lias.
How can users experiment with the tool?
-Users can experiment with the tool through a demo that is provided, which helps them understand how the tool works.
What is the role of the red node in the workflow?
-The red node, which is likely from another package, is responsible for disconnecting an object from the background.
How does the 'remove background' node function in the workflow?
-The 'remove background' node is used as a replacement for the red node to disconnect the object from the background in the workflow.
What is the significance of the mask created in the process?
-The mask plays an important role in the process as it helps to create a more harmonious image and affects the lighting and shadows in the final result.
What is the effect of changing the 'keep proportion' setting to true?
-Changing the 'keep proportion' to true corrects the proportions of the image, making it more accurate and less distorted.
Why might the image quality not be good after making adjustments?
-The image quality might not be good due to the adjustments made, and it might work better without adding a background image.
How can the lighting in the image be optimized?
-The lighting can be optimized by adjusting the position of the mask, changing the blur radius, and using the IP adapter to moderate the effect.
What is the purpose of the IP adapter in the workflow?
-The IP adapter is used to adjust the lighting and create a smoother transition between the object and the background in the image.
How can the final result be improved by adjusting the 'IC light conditioning'?
-The 'IC light conditioning' allows users to play with the multiplier, which can be used to raise the contrast and improve the final image result.
What is the final step in enhancing the image?
-The final step is to add the IP adapter to the image, which helps in achieving the desired lighting and contrast for the final result.
