I need your help and advice once again! I will be an official photographer on the classical music concert on Saturday night! the music was written by Penderecki - well know Polish composer, and he will also conduct the concert! The whole city knows about this event... and the ticket price is very high... that's why I'm very happy that I will be there and I will take pictures officially. Also I may shoot backstage and before the concert. I know that the light would be very good - the cocert is in the harbour - because of the anniversary of strikes there in 70's and 80's (a few people died there). and the person who directs the light is a pro - he did it for most concerts around Poland. So... i need any advice which you can provide... if you have an experience in such photography PM me or write tips'n'tricks below thank you in advance Cheers! P.S I need even tiny advice such as what to wear... should I wear something... smart? or no? People there will be in official suits and what about me?
