While there may some "ambiguity" in the question raised by the threader starter, the essence of his question is totally "non-ambiguous".
Basically, he was trying to find out the prefered working methods of photographers.
And as always, there will be many working methods.
I loathe to work with others. Of course there has to be a subject to be photographed - whether that be still life, landscape, streets, documentary or person/model. In photographing portraits, one of course need a "model". But the essence of my working method is to work "alone". Unlike espn who find working with a model for 20 mins led to the same pose, I actually work with ONE model for at least two hours, if not more. My longest is working with ONE model for a day. No props. No make-up artist. No art director, etc. In fact I am toying with the idea of an extended session working alone with ONE model for several days.
I fing that for my kind of photography, having others around is distracting, and confuses my feelings.
On the other hand, PBS, works with a team of people. Time and again, PBS emphasised that his works are a result of teamwork. And the people who attended his course can attest to this. And I supposed PBS needs to work in a team, because of the type of images he produces (at least those I see here).
So there are different working methods, depending on personality,and the type of images you want to produce.
