I don't get why the designers don't intervene and tell the photographers to knock it off, by designers I don't mean the person we all know, but someone from the media relations / event planning / public relations side of the design house. Forget the models, they should be concerned about the buyers, editors, valued customers and other VIPs in attendance. I know models are supposed to look stoic and perhaps it's my imagination, but a number of the models at the Fall 2009 Pucci show look uncomfortable especially at the beginning of the video. Now it could be the photographer or not understanding the gameplan, but a few of them, top girls at that, just don't look very "with it."
I cannot believe that the design houses have any real fear that the photographers will boycott their show or take crappy pictures if they are asked not to yell and to be respectful. I assume that Vogue is the biggest media outlet and I think even they would think twice about getting shirty over a request to not yell or be rude, after all it is in their best interest to remain a go to source for runway pictures from the big shows. IIRC there was a situation where Lagerfeld wanted photographers to dress a certain way and the photographers balked at that, now I don't think that making such a request is unreasonable (within reason), but I can see there being pushback - I don't remember what the final outcome of that was, but again asking photographers not to yell and be rude is not a ridiculous, diva-fied request.
Now I can see the photographers getting frustrated if the layout and "choreography" do not allow for them to get good footage. I was very frustrated a couple of seasons ago when it seems like the "in" thing for the runway shows was what I called the conveyor belt method - the models would walk to the end of the runway and make a smooth turn - there was no stop-and-pose step. Again frustrating, but hollering at a model following instructions isn't the way to go.
