They blur NCIS because they want to make Mark Harmon look a little less old than he really is. I have always hated that about the show. I love the show , but really hate the picture quality. Even brand new episodes look faded and blurred out like an old show. Reminds me of when Barbra Walters is on the View and the set looks sharp till you see Barbra and then it looks like a vaseline blurred mess on her face. She is in her 80s so I guess they are trying to hide what an hd camera would do to her .
You hit the nail on the head. Many stars HATE HD for that reason, and Harmon has a face like the surface of the moon. Probably both star and producers are in agreement with how soft to shoot the show, or it can be done in post production, keeping the source sharp for, say Blu-ray release.
FWIW, if you remember the old Bob Newhart show from the 1980's named
Newhart (set in a Vermont Inn), the first season of that show was VIDEOTAPED. However, Bob Newhart thought he looked too old, so he had the producers switch to FILM, which soften things quite a bit. Ironcially, all they had to do was switch the "DETAIL" off at the video control and it would have softened things up quite (Detail was shut off on quite a few shows in that era) well enough, but "old" Bob knew film, and demanded FILM. I always thought the Videotaped episodes of
Newhart looked superior with much better nuance on the lighting for warmth and effect, but once they decided to make the comedy on
Newhart childishly silly along with the switch to film, they just threw light EVERYWHERE and brightened everything as flat, just like one would on silly sit-coms and game shows.
