There are a few other places we would like to direct you to for support, both from Microsoft and from the community.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality.

If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.

And always feel free to hit us up on Twitter @MxdRealityDev.

    This isn't something the HoloLens does natively. Though you could try saving an image with the RGB camera, enlarge it and place it in your scene.

    There's no zoom on the rgb camera so I think the best you can do is enlarge a small area of the captured image.

    Instead of a single frame you could get access to the video feed from the camera. From there you can get the users gaze and determine which part of the video stream (which pixels) the user is effectively looking at by using the APIs for converting application-specific coordinate system to camera pixel coordinates. From there you could zoom in on that area of the feed, copy a block range out, scale it up, and present it in some way.

    I don't have code for this, but from the samples I've seen it should be possible in theory. I would start with this article here on the Locatable Camera.
