Dance competition set up was a complete fail. The dancers pretty much performed to the judges only. 90% of the crowd only saw mostly the dancers' backs. It would be pretty easy to solve that by placing the judges in the crowd's front row. I'm sure other solution are available too. What made this even more silly is that you had at least 5 official cameras recording it, yet on the projectors you showed input from the cameras that also filmed the dancers' back. That was a really WTF, and ruined that event for me (and many others).
As far as I was aware, the camera at the back (on the sound deck) was the only 'official' one which was being used, at least 3/4 cameras were BBF cameras and then there was my camera (my camera being one which was facing the audience on a tripod) and another one operated by someone else.
The problems with the screen was a pain and I'll agree that having the dances judge facing was a bad move as then all the audience would get is a view of dancing furry backside.
I agree with judges should be in a primer spot in the audience and thusly everyone gets a mostly equal view.
