To access the Pictures library folder, you will need to set the Pictures Library capability in your project. To do this in Unity, go to Edit > Project Settings > Player. Then in the Inspector, select the Windows Store icon (the green one), expand Publishing Settings and check PicturesLibrary.
You can get an instance to the folder (a StorageFolder object) from KnownFolders.PicturesLibrary.
Thanks!

Do you want to do this from within the app or from outside the app? Within an app you can get images from the WebCam. In Unity you aren't yet able to automatically include holograms on the image. From outside the app you can use the rest API on the developer website. @DavidKlineMS has experience with some of the rest API, but I don't recall if he implemented getting live frames from the device.

Here's how to access the webcam from Unity:
https://developer.microsoft.com/en-us/windows/holographic/locatable_camera_in_unity
and some general information:
https://developer.microsoft.com/en-us/windows/holographic/locatable_camera
THank you both for the information. Yes, this is inside the App. I would like to add barcode scan to my App. Is there any lib I can use for barcode scan?
@Pentose, I copied the camera code from https://developer.microsoft.com/en-us/windows/holographic/locatable_camera_in_unity to my project and it ran file. Ｉcan see that it said "Saved photo to disk!". However, how can I find this photo on hololens? I could not found it in the Photo App.
Thanks,

@Fireman, within your application, can you see the file? The sample code you mention saves the file into your application's persistent data store (Application.persistentDataPath).
Thanks!

If you want to view the picture in the Photos app, you'll have to save it to the Pictures folder. See this thread for more information: http://forums.hololens.com/discussion/comment/1661/#Comment_1661
@Pentose, I checked the thread, one post mentioned that the photo App path is something c:\xxx. Is this right? I do not expect a "C" drive on hololens
HoloLens runs Windows 10. There's a C drive and a user and the user has a pictures folder just like on desktop Windows.
