    • HDR Photography
      • Set of Techniques with origins dating back to 1850s
      • Allows greater ranges of luminance between light and dark areas of an image
      • Achieve details in the highlights and shadows of an image at the same time
    • Under and Overexposed Images
    • Viewing Problem
      • Traditional screens (CRTs, LCDs) and printers display a low dynamic range (LDR) of luminance (300 levels)
      • Human eyes have a high dynamic range of luminance detection (50,000 levels)
      • We don’t have a good way to view real HDR images (yet)
    • Tone Mapping
      • Until display and print technology catches up we have to map HDR images to LDR images
      • Global and local algorithms
      • Tries to balance strong contrast reduction and image details in shadows/highlights
    • Tone Mapping Demo
    • Panoramic Photography
      • Elongated field of view (160° x 75° or greater)
      • Techniques dating back to 1850s
      • Rotate camera about the nodal point
        • the optical point from which the focal length is measured
      • Eliminate parallax
