'Doon of Photography'....................................?

You're going to have to clarify that before anybody can give you a reasonable answer.

I'm assuming you meant to say "Don of photography"

If this is the case, and you're attempting some colloquial metaphoric comparison, then take your pick of whatever renown photographer you like.

There is no single photographer these days that dominates every facet of the craft as a Don of the mafia would rule his world of organized crime...
