I've heard it's forbidden to photograph on gigs with systems camera without a somekind of permission from the band or something like that
That's not true, at least not for the Poets and this venue. I take my DSLR to their gigs all the time. The only thing the guys do not allow is flash photography (and I'm not sure about professional video cameras), but less than that they are pretty easy going about pictures. soemtimes the venues won't allow system cameras though (e.g. the Nosturi in Helsinki does not). As for other bands - have no idea.
Ok, I just wanted to know because I got a systems camera as a birthday gift and I wasn't sure if it is allowed to take pictures on the gig with that kind of camera (my dad told me something about photographing with that kind of camera isn't allowed usually), so I brought my digital camera with me instead. And before the gig day I looked Virgin Oil's site for the frequently asked questions about photographing and there said something like this: "Photographing is allowed with regular cell phones and digital cameras. If you want to use video or systems camera, you'll have to contact to the band's agent if it's ok to use those kind of devices to photograph or film."
But thanks about the information you gave me redbossfan, good to know for the future gigs
Btw, I have to say that I'm embarassed, because I took some pictures with the flash but this was my first time using it and I won't do that again, I'll be nice next time
