Is there a general consensus that I'm not aware of regarding the etiquette of holding foot traffic up to take a photo in public?
This is most apparent where it is a group photo with a public monument in the background, the photographer maybe 2 to 5 metres away usually perpendicular to the general flow of foot traffic on a sidewalk. Thereby causing an invisible but apparently socially powerful barrier to passage.
It seems that the bigger the group, the more pressure there is not to interrupt it. Often happening around public venues/concerts, places of interest, university graduations, public transportation. Busy places.
Personally, unless the photo is clearly about to be taken, I just walk through the foreground. Otherwise, experience has made it clear that there is always some reason not to take the photo 'quite yet', and you'll be waiting for someone to adjust settings on the camera, get the group to huddle more, someone's missing, so and so's phone just rang etc.
What prompts this question is that I think I may be in the minority? Other folks will stand and wait (!), to the point that there is an impenetrable barrier of actual people that I cannot get through even if I wanted to.
Often the photographer will be gracious at the end, but often enough there is zero gratitude and they simply 'allow' the people who have been waiting to continue their way - which is rude, in my opinion.
When should one wait to cross and when should you just go?
