However error control for inverse graphics is difficult, and inverse graphics methods can represent only the effects of the chosen intrinsics.

A few days ago, Microsoft announced via the Windows Insider blog some new AI features and improvements for the Photos app. Among the new features is "Relight," which lets you adjust the lighting in a photo by placing up to three virtual light sources that can each be adjusted for color, intensity, and direction. There are also several built-in preset styles for quicker adjustments. With Relight, you can use the power of AI to dramatically change the mood, tone, and appearance of any photo. However, you'll need a Snapdragon-powered Copilot PC to take advantage of this feature right now.

Image relighting is the task of showing what a scene from a source image would look like if illuminated differently. Inverse graphic schemes recover an explicit representation of geometry and a set of chosen intrinsics, then relight with some form of renderer. But error control for inverse graphics is difficult, and inverse graphics methods can represent only the effects of the chosen intrinsics. This paper describes a relighting method that is entirely data-driven, where intrinsics and lighting are each represented as latent variables. Our approach produces SOTA relightings of real scenes, as measured by standard metrics.

Over the course of the last few years, Skylum made a name for itself with a set of photo-editing apps like Aurora HDR and Luminar. With Luminar AI, it is now launching a brand-new photo editor, starting at $79. The new application, available as a standalone product for Mac and Windows and as a plug-in for Lightroom and Photos for MacOS, was built from the ground up and offers many of the traditional photo-editing features you're probably familiar with from the likes of Lightroom. The focus, though, is on its new AI-based tools, with a special focus on editing landscapes (and skies in general) and portrait shoots. In total, Skylum added 13 AI features to the application.
