How to Take Screenshot in Windows Mixed Reality in Windows 10
Mixed reality blends real-world and virtual content into hybrid environments where physical and digital objects coexist and interact.
Mixed reality capture (MRC) lets you capture your mixed reality experience as either a photograph or a video. This lets you share the experience with others by allowing them to see the holograms as you see them. Such videos and photos are from a first-person point of view.
Mixed reality capture photos are saved as a 1408x792px (HoloLens) or 1920x1080px (Immersive headsets) .jpg file to your Camera Roll folder (C:\Users\<username>\Pictures\Camera Roll).
This tutorial will show you how to take a screenshot while in Windows Mixed Reality using an immersive headset in Windows 10.
