About spherical panoramic images
Panoramic images capture more than a traditional camera frame, while spherical images combine multiple panoramas to cover 360 degrees all around, and 180 degrees above and below. This unusual image can be projected as a sphere around the viewer, with details in every direction, providing an immersive experience. There is no frame to limit the view, or any "behind the camera" area in these carefully composed photo creations.
Adding HDR
Multiple exposures (covering the lightest and darkest parts of the surroundings) are captured by the camera, and later compressed into a single image with high dynamic range. The resulting image file is as close as is possible with current technology to what a person might see while looking at the highlights and shadows with their own eyes. Even the limits of modern cameras are overcome, with a greater color and tonal fidelity than any screen can convey.
