💡IC Light

IC Light is a project designed to manipulate the illumination of images. It is unique because it uses text condition relighting to adjust both the model and the background within an image. This project is particularly interesting because it takes a different approach to image manipulation, resulting in improved outcomes. The script mentions that IC Light is available on GitHub, allowing users to install and use it for their own image editing purposes.

💡Text Condition Relighting

Text condition relighting is a technique used by IC Light to adjust the lighting in images based on textual prompts. This method allows users to specify the direction and nature of the light, such as 'Sunshine from window' or 'neon lights', and the software will apply these conditions to the image. It is a core feature of IC Light, enabling more nuanced and creative control over image lighting.


GitHub is a web-based platform for version control and collaboration used by developers. It allows users to manage and review code, as well as track changes made to it. In the context of the video, GitHub is where the IC Light project is hosted, providing a link for users to access the code, installation instructions, and other relevant information.


Gradio is a Python library used for quickly creating web demos and deploying machine learning models. The script mentions a 'background condition demo on Gradio', which implies that IC Light has a demo version available that users can interact with online without the need to install the software, showcasing its capabilities in a user-friendly interface.

💡Hugging Face

Hugging Face is an open-source platform that provides tools for developers to build, train, and deploy machine learning models. The script refers to a demo of IC Light being available on the Hugging Face space, indicating that the platform is used to showcase the project's functionality to a wider audience.


In the context of IC Light, a prompt is a textual description that guides the software on how to manipulate the lighting in an image. For example, a user might input a prompt like 'beautiful woman detailed face neon lights' to achieve a specific lighting effect. Prompts are a key part of the text condition relighting process.


Relighting refers to the process of changing the lighting conditions in an image after it has been captured. IC Light specializes in this by using text-based prompts to guide the software in how to adjust the light sources, direction, and intensity to achieve desired effects. It is a significant aspect of the software's functionality.

💡Seed Image

A seed image in the context of IC Light is the original image that the user wants to manipulate. The software uses this image as a base to apply the text condition relighting, ensuring that the final output matches the user's vision. The script mentions adjusting image dimensions to match the seed image, highlighting the importance of maintaining the original image's integrity.

💡Advanced Options

Advanced options in IC Light provide users with more control over the image manipulation process. These may include settings for the number of steps in the relighting process, noise reduction scales, and additional prompts. The script discusses these options as a way for users to fine-tune their image editing to achieve more complex or specific results.


Blanca is likely a person or a model featured in one of the images used in the demonstration of IC Light. The script mentions using an image of Blanca to showcase how IC Light can manipulate the lighting of a real photograph, suggesting that the software is capable of handling both AI-generated and real-world images.

💡AI Images

AI images refer to images that are generated by artificial intelligence, as opposed to being taken by a camera. The script mentions testing IC Light with both real images and AI-generated images, indicating that the software is versatile and can be applied to a range of image sources. This highlights the potential for IC Light to be used in various creative and technical applications.
