I'm not a big Testino fan but your comment is a bit perplexing so I just have to say that while a brand might rely heavily on the visual cliché his customers expect in order to follow them as an ideal of what's "British", I don't think the team that worked to achieve the concept should necessarily be measured by nationality, especially not someone like Testino who's been around long enough to prove he's a highly skilled photographer that hasn't cowardly cornered his work by photographing only his own "exotic" (?) background and is certainly NOT recognised for that but more for his ability to digest and explore different aesthetics and scenarios and translate it all into memorable imagery, which might explain why he was chosen by Burberry as he's probably experienced enough to know what a customer could expect from an All-British label instead of using the now-so insipid David Sims to take a photograph worthy of a studio ed for either Japanese or American Vogue as his work hardly exhibits his identity as a photographer, even more less as an English man IMO.
I can understand how a model or a landscape speak more than a thousand words but a passport over skill for those behind the lens?, a bit limiting, don't you think?.
