IC Light AI is an artificial intelligence tool that allows users to manipulate and control the lighting in their images, specifically focusing on portrait photography. The tool provides the functionality of relighting images based on text prompts or background images, achieving consistent and personalized illumination. Users can adjust lighting parameters for their portrait photos to fit new environments with precision. Text-conditioned relighting enables users to describe their desired lighting using natural language, and IC Light AI interprets and adjusts the lighting in the image accordingly. Background-conditioned relighting allows users to use a reference background image, from which IC Light AI analyses and applies the ideal lighting to the portrait for a harmonious result. This AI tool caters to professional photographers, social media enthusiasts, everyday users, and e-commerce businesses, providing them with the ability to optimize lighting in portrait photos, enhance their attractiveness and texture, and create eye-catching visual content.
