"Accidents" do happen.
I saw a photographer knocked down the "Long Fong" candles from the altar. He was moving backwards at that moment while trying to take photos of my friends returning home for tea ceremony. The two candles actually fell onto the ground and extinguished!
I take wedding photography sometimes too, just feel that you need to be extra sensitive and considerate during those times, especially when u r not the only person covering the event. There are times you are so engrossed in the job that you "forget" about other people or things happening around you. Just like the lady in the video.
There was once i covered a wedding. This videographer was so dominating during the shoot that he kept zooming the camera in and out. When i said "zoom", he din used the zoom function on the camera. He was in fact physically moving in and out, all the times, in a small HDB house. He can even moved like close to 10cm from the subject!! Most of the times, I was trying very hard to avoid getting him into the pictures. He seemed to forget that there's another person trying to take pictures too.
That's the reason why sometimes i need to remind myself to give some space and opportunities for others too, while concentrating my photo takes. Well, guess we are all trying to get our job done after all.
Having said all that, if one day i am videotaped, i hope i wouldn't behave like those irritating photographers caught on tape!!!!
