Blocked shadows, английский
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.
1080i, английский
Similar to 1080p video, the “i” stands for “interlaced,” which differs from 1080p (progressive) video in that each frame contains two fields of data (but typically has double the frame rate). while progressive video is too large for broadcast, 1080i exists primarily for broadcast use, as the lower frame rate allows the signal to be sent over 60 hz systems. the signal is 60i for ntsc or 50i for pal.
