Much inspiration received by reading you guys here. Many thanks.
I went up to "Oh My Gosh Point" last year to shoot a full 360° panoramic VR image of the scene. You can find it at:
http://www.vrphotography.com/yosemitefalls/Use your mouse to click and drag within the image in order to pan and tilt the view. You can also zoom in and out using the Shift and Option/Alt keys on your keyboard. The buttons at the bottom of the screen can be used for navigation, as well. For the best user experience, click on the Full Screen button (press ESC to return to normal viewing). On an iPad or other tablet/smart phone, you should be able to simply move the tablet/phone itself in order to change your viewing direction, and to pinch for zooming in/out.
Once you've had a look around, click on the red target above the top of Yosemite Falls to be transported to another 360° VR view shot from the top of the falls.
Both images were shot with the camera mounted on a long extension pole, in order to give a more interesting perspective from beyond the rail.
I'm in the process of planning a series of similar images from other classic viewpoints in the park. Suggestions are most welcome. Currently on the list: Half Dome summit / cable route, Nevada and Vernal Falls, Fern Ledge, Indian Rock, North Dome, etc.
Thanks again!
