I have really been enjoying a recording of U2 Rattle & Hum from MHD. I like the music and I am very impressed by the artistic quality of the photography during the concert portions. I had a production process inquiry that some folks here may know the answer to. I have seen live productions going to air where the director chooses which camera shot goes to air. I am wondering if a similar process is used for concerts like this, where only one camera shot is ever recorded to a master. Or is it the case that many of the camera shots are recorded and then the editing is done later to pick a good assortment of shots? I realize that the answer could vary depending on the specific concert. Any insights by experts in the know are appreciated. Thanks in advance.
