For Cardboard VR headsets, view still 3D photos of Mary Kate modeling for a fashion photo shoot.
Click on screen or use remote bluetooth controller Enter key to advance to the next photo.
By default the app is in Zoom mode. Pressing the volume up key toggles between zoom or fixed modes. In Zoom mode you roll your Cardboard VR headset right to zoom in (magnify) and roll left to zoom out (shrink). Reposition to an area of interest by moving the headset up/down or left right. Press the volume up key again to save the zoom level and continue viewing photos at your preferred fixed magnification level. Or stay in Zoom mode and advance to the next photo with the Enter key and reposition as you like.
In either zoom or static mode you can use a bluetooth game controller in "game" mode to zoom and move within the photo. See controller key layout at http://www.tekla3d.com/3d-vr-reel-controller-keys.html
The Mary Kate fashion photos are stored as 4K images. With a high resolution phone like the Samsung Galaxy S6 or S7 you will be able to see finer dress detail when you zoom in.
