I believe Paul Rowland is a photographer, at least from what I Googled. It does seem to say he’s an agency boss on the one photo with a caption. Maybe a modeling agency?
UPDATE: Thanks to Jessika, we have some information on Paul Rowland!
The caption in the last pic says that he is a model agency boss. I Googled him and found the following on the website of the German Elle Magazine:
Paul Rowland founded the model agency Woman Management in 1988. The agency’s vision was to represent “unconventional beauty”. In their first years the agency was looking for women, who didn’t correspond to the typical ideal that dominated the fashion scene of the 80s. Even today extraordinary models like Agyness Deyn are listed in the agency. Women Management has it’s headquarters in New York. They have further offices in Paris and Milan.

They also say that they have launched the career of Kate Moss (among others).

And here is a blog post about him:
He also was a model and is now a photographer.
