During the day I shoot like 1000-2000 frames. Stats- members of public calling Police- av 0% Pictures with POs including selfies ab 15-30 a day. Pictures of people assulting me by pointing middle finger at me ... countles. That is what community give back to documentalists back... Don't mention 2000 Pounds of damaged equipment this year aloneie when trying to avoid phisical assoult by a member of public or rushing to get that frame. And when you look closer at the crowd you will find out how many people do this sort of photography. I never sneek with the camera hidden- to show that my intentions are good. There's that many styles as photographers in the world and this make positive diversity. There's no bad or good methods as far as at the end of the day you get that picture you doing it for.
