Advanced High Dynamic Range Imaging, 2nd Edition

Preface

The human visual system (HVS) has not changed much in the last 40,000 years. Imaging techniques, on the other hand, have changed dramatically in just the last 5 years, since the first edition of this book appeared. While the HVS is able to see up to 20 f-stops of lighting in a scene with minimal eye adaption, and from starlight through to bright sunshine with full adaption, traditional imaging (or low dynamic range [LDR] aka standard dynamic range [SDR]) techniques are only capable of capturing 8 stops. This is now rapidly changing. As Figure 1 shows, high dynamic range (HDR) is providing a step change in imaging with its capablity of capturing and displaying detail in the very brightest and very darkest parts of a scene simultaneously. ...
