I think Examples and The Making of 40 Photographs are referring to the same book?
One of my favorites for his landscapes if The Portfolios of Ansel Adams:
"A good photograph is one that makes the viewer so aware of the subject that they are unaware of the print."- Kodak
"...if you find afterwards that you made a mistake, the price of the film and chemicals was...tuition!"
"The hard part isnít the decisive moment or anything like that Ė itís getting the film on the reel!"
- John Szarkowski
