I have added some new quotations to http://billallsopp.com/photography-quotes-2/
The first is perhaps the best to date.
One eye of the photographer looks wide open through the viewfinder, the other, the closed looks into his own soul.
To be ready is one thing, to be able to wait is another; but to seize the right moment is everything.
Make visible what, without you, might perhaps never have been seen.
I give the moment permanence.
Manuel Álvarez Bravo
To make the essence of man visible in the exposure is the highest art of photography.
