What is the importance/role of photography in Swiss Style?

Hello all,

I'm doing an assignment on the influence of photography in Swiss Style/ITS.
As in how did photography came about in Swiss Style.
I found sources writing it gives an impression of realism and more drama, I found more similar answers but I am looking for a more in-dept answer, I'll really be very grateful if I get your replies.

Thanks in advance for your comments on this topic !
