One key feature of the ic-light model is its ability to produce highly consistent relightings, even to the point of being able to merge the resulting shadow and normal map information. This is achieved through the model's "Imposing Consistent Light" approach, which ensures that the blending of different light sources is mathematically equivalent to the appearance with mixed light sources.

The ic-light model is a fork of the original ic-light model created by zsxkib, which allows for image relighting at any resolution. It is designed to manipulate the illumination of images, enabling users to automatically relight their images based on text prompts. The model comes in two variants: a text-conditioned relighting model and a background-conditioned model, both of which take foreground images as inputs.

Off axis parabolic mirrors are used to direct and focus all the incoming collimated light into a single focal point due to the surface shape parabola.

ic-light is an AI model developed by zsxkib that can automatically relight images. It can manipulate the illumination of images, including adjusting the lighting conditions, adding shadows, and creating different moods and atmospheres. The model is capable of producing highly consistent relight results, even to the point of being able to estimate normal maps from the relighting. This consistency is achieved through a novel technique called "Imposing Consistent Light" which ensures that the blending of different light sources is mathematically equivalent to the appearance with mixed light sources. The ic-light model is similar to other image editing and enhancement models like GFPGAN, which focuses on face restoration, and LedNet, which handles joint low-light enhancement and deblurring. However, ic-light is specifically designed for relighting images, allowing users to adjust the lighting conditions in creative ways. Model inputs and outputs Inputs Prompt**: A text description guiding the relighting and generation process Subject Image**: The main foreground image to be relighted Lighting Preference**: The type and position of lighting to apply to the initial background latent Various hyperparameters**: Including number of steps, image size, denoising strength, etc. Outputs Relighted Images**: The generated images with the desired lighting conditions applied Capabilities The ic-light model can automatically relight images based on textual prompts and lighting preferences. It can add shadows, adjust the mood and atmosphere, and create cinematic lighting effects. The model's ability to maintain consistent lighting across different relighting conditions is a key strength, allowing users to experiment and iterate on the lighting without losing coherence. What can I use it for? ic-light can be used for a variety of image editing and enhancement tasks, such as: Enhancing portrait photography by adjusting the lighting to create a more flattering or artistic look Generating stylized images with specific lighting conditions, such as warm, moody bedroom scenes or bright, sunny outdoor settings Adjusting the lighting in product or architectural photography to better showcase the subject Experimenting with different lighting setups for CGI or 3D rendering projects The model's consistent relighting capabilities also make it useful for tasks like normal map estimation, which can be leveraged in 3D modeling and game development workflows. Things to try One interesting aspect of ic-light is its ability to generate normal maps from the relighting results, despite not being trained on any normal map data. This suggests the model has learned to maintain a consistent 3D lighting representation, which could be useful for a variety of applications beyond just image editing. Another interesting feature is the background-conditioned model, which allows for simple prompting without the need for careful text guidance. This could be useful for users who want to quickly generate relighted images without the overhead of fine-tuning the prompts. Overall, ic-light is a powerful tool for creative image manipulation and lighting experimentation, with potential applications in photography, digital art, and 3D modeling.
