In the 1970s it seemed common for tv shows to be shot on video in the studio but on film outside, perhaps because video cameras were too large or sensitive for outdoor use. The audience simply became accustomed to the large difference in appearance between indoors and outdoors in tv shows. IIRC, Doctor Who and Benny Hill went through this change during episodes frequently. It also reminds me of the first time I went over to a friend's house who had a large tube standard def tv after I had switched to HD. The scanlines that had always been invisible to my brain were suddenly very obvious. Funny how we adjust.
