HiHoSilver, it is stunning and mind boggling to read that you had not heard of Irving Penn. Absolutely one of the most important photographers of all time. He established a portrait style that persists to this day as well as a fashion photography style. His enlarged platinum prints are in every museum in America. He has several large well made books that I think I own most all of. When he was still alive I flew from Portland to Chicago to see his show in the Art Institute, a range of prints that he donated (I think he donated). There is a book of that show as well. He is probably the greatest Platinum printer ever to live. I had a chance here in Portland to hold in my hands a couple of 16x20 unframed platinum prints mounted on aluminum plates, I got to carry them over to the window and study them. It is no exaggeration to say they changed my life forever. You really should spend some time studying him if you care about the finest art of photography.
