I've been following this thread with interest although I'm none the wiser as to what a master really is.
I love to follow the Hasselblad Masters on their website
And to quote hasselblad.se
"The Hasselblad Masters represent photography at its finest; at its most inspired, most communicative, most beautiful. They are young, old, western, eastern, classical, experimental, traditional, modern, and futuristic. They have perhaps but one thing in common: they are masters at conveying an instant, an emotion, with images. Masters of the art and craft that is photography."
