Linkin Park photos analyzed

These are more Linkin Park photos, but this time I had the advantage. Even though my gear isn't what it used to be when I shot concert photos with a still camera, especially when you really need to have a lens that opens up with a wide aperture of at least a 2.8, which I don't have, I did alright. I lose out on the action shots which become less sharp with the slowed down shutter speed, but I did make up with access. In a normal large concert, I guess the limit is three songs in the front area which is in front of the crowd and in front of the security staff as well. One thing I didn't know is when a person crowd surfs, the security guards who recognize it, raise their arm like in a “Heil” type of position. Perhaps it's the alert the guard next to him that someone is on their way and could end up in their zone.
