Well I got a point and shoot and I never use flash unless the artist says with their own mouth it's OK. (At an Imogen Heap concert, she put on her sunglasses and posed so everyone could get a great pic with flash
) Mostly though, it's just so annoying! If you are right near the stage though, (Which I'm gonna do, because I always get to general seatings early :D ) you don't even need flash because of the lights. If all else fails, if they so no cameras at all, and I see people getting in trouble when they take theirs out and snap away, I keep it in my pocket.
One last question for you guys. I blog... ALOT...and I was thinking to make things easier... Would you guys like me to make a seperate Myspace, just for my concert travels? I was thinking that way all the pictures, vids, and blogs are right there! Just artists! :)
