I don't get why people analyze HCB to death. Just because he did something, doesn't mean every street photographer needs to do the same. Many street photographers are actually quite introverted and the techniques HCB used may be too daunting for them. The bottom line is, if you get the shot without dehumanizing your subjects, who cares how you got it? People fixate far too much on how and with what a street photographer got their iconic photograph. Going up to people and asking is alright sometimes, but to create a nice balance, real candids need to be in any street photographer's portfolio. Real candids don't need you provoking people by using your expensive camera as a yo-yo.
