You're right, Ray. Here the common rule at any concert is "No sound recorders, no video camcorders, no professional SRL-cameras". Some foreign bands do not allow any cameras at concerts, but it's said to be because of their record labels' orders.
The only time I know Nightwish did ban all cameras (it was well informed before) was at Hartwall Areena in 2005 due the fact that they were filming the EOAE-DVD and didn't want to have a bazillion cameras flashing all the time and ruining the footage. Other than that, it's always been OK to take pics at thier concerts.
Nw.com webmaster Jarmo told us a couple of weeks ago, that they had a talk with the band and the management about how to deal with the mostly poor quality videoclips taken from concerts with digicams and cellphones. Those are unavoidably appearing at YouTube nad similar websites, and they decided not to fight it but rather try to make use of the phenomena by providing some better quality concert footage on their own website when they are ready. Maybe not from this leg of the tour, but sometime later next year. We'll see if/how it will work.

Camera check-in means that you leave your camera at the check-in booth and get a numbered badge or a receipt to collect it on your way out. For the $X charge they guarantee to keep it safe so nobody can steal it. In Finland we are used to have these type of check-ins at every venue, theater, concerthall and at festival gates for all the things you are not allowed or don't want to bring in, like (winter)coats, backpacks and whatnot. Very handy indeed, never need to worry someone stealing your things when you can leave it guarded at the check-in.
