Term for lack of, or loss of, shadow detail in a photographic image, usually the result of underexposure or images captured by a lower resolution (and less dynamic) imaging sensor. Although lost shadow detail can often be (partially) reclaimed in photo-editing applications, HDR (High Dynamic Range) imaging—in which two or more bracketed images are sampled and combined into a single image file containing increased levels of shadow, highlight, and mid-tone detail—has become an increasingly common in-camera solution for retaining both shadow and highlight detail.
