Relight AI

Relight AI, part of the ClipDrop suite by Stability AI, is a specialized artificial intelligence tool that allows users to completely change the lighting of any photograph. Using advanced AI, it analyzes the 3D structure of objects in a photo and creates professional studio-quality lighting effects by adding virtual light sources from different angles, colors, and intensities. This technology makes it possible for anyone to achieve stunning visual results without expensive studio equipment or complex photo editing skills. Relight AI can deliver in minutes what professional photographers achieve spending hours with thousands of dollars worth of equipment.

The tool offers users the ability to add multiple virtual light sources to a photograph. Each light source's position, color, intensity, and angle can be precisely controlled. The AI calculates how light will reflect off object surfaces, where shadows will fall, and how ambient light will affect the scene using physics-based rendering principles. The result is a natural and convincing lighting effect that looks as though it was captured in a real studio. Users can choose between point lights, diffused lights, and directional lights for maximum creative control. Light sources can be positioned using drag-and-drop, with changes visible instantly through real-time preview. This interactive approach transforms the trial-and-error process into an enjoyable and efficient experience.

One of Relight AI's greatest strengths is its performance in portrait photography. The model deeply understands facial geometry, creating natural shadows along facial contours and adding eye catchlights. It can transform a casual selfie into a professional-quality portrait or convert flat lighting into dramatic Rembrandt lighting. For product photography, it provides even illumination from every angle, elevating the quality of e-commerce visuals. These capabilities appeal to a broad user base ranging from professional photographers to online sellers. Industry-specific lighting scenarios can also be successfully applied, such as warm and inviting lighting for food photography or bright and sharp light for jewelry shoots.

The platform's batch processing feature applies the same lighting settings to dozens or hundreds of images, ensuring consistency across entire shoots. This proves invaluable for product catalogs or social media content series that require uniform visual quality. Relight AI also supports HDR lighting maps and environmental lighting for even more realistic results. A preset library enables one-click application of popular lighting scenarios, from golden hour warmth to cool studio lighting, from neon night effects to soft window light. Users can also create and save their own custom presets to ensure consistency across projects and establish a signature visual style.

As part of the ClipDrop ecosystem, Relight AI integrates seamlessly with other AI tools like background removal and image enhancement. Free usage is available at limited resolution, while Pro subscriptions unlock high resolution, batch processing, and API access for workflow integration. Relight AI fundamentally simplifies post-photo editing processes, making studio-quality lighting accessible to everyone regardless of technical expertise. Its continuously evolving AI model pushes the boundaries of professional results with more natural light simulations and broader scene understanding with every update. Lighting control in photo editing workflows is no longer a technical barrier but has transformed into a creative playground of endless possibilities.
