The document provides an introduction to HDR (High Dynamic Range) panoramic photography, highlighting its historical techniques and the challenges in displaying HDR images on traditional screens. It discusses the need for tone mapping to adapt HDR images to low dynamic range displays and lists essential tools and software for capturing and processing panoramic photographs. Additionally, it emphasizes the importance of using manual settings and specific camera equipment for optimal results.

3. 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

4. Under and Overexposed Images

5. 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)

6. 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
