Interesting thing about Ansel's later prints is the way his printing changed. As he got older, his printing edged towards higher contrast. During a Q & A with John Szarkowski, at the end of his talk on Adams, I asserted as Adams aged, his eyesight changed and so that is why his prints became more contrasty. Szarkowski brushed me off, rather arrogantly. John died a year later. ... A few months ago, I revisited Windows and Mirrors. I don't think that book has stood the test of time.
