As regards cameras, I was honestly surprised to see that flash photography was allowed. I think this does an injustice to the skaters. It blinded me when I saw it, so I can just imagine what it must do to the skaters, competition can be won or lost by being blinded by a bright flash.
Thank goodness the guy I was sitting next to had a camera that did not have a flash. In fact one of the workers at the event came up to our first row seats, him specifically, and asked if he was using flash photography. She said there had been complaints by fellow attendees whom thought the flash was coming from our section, and we all said emphatically "N-O". It wasn't us. I just had my digitial camera, my niece her cell phone, and the guy next to me his fancy expensive camera without a flash. That's it.
