I know the importance of highly trained awareness of the “moment” and the immediate and intuitive response of the photographer. It should be obvious to all that photographers whose images possess character and quality have attained them only by continued practice and total dedication to the medium.

The next time you pick up a camera think of it not as an inflexible and automated robot, but as a flexible instrument which you must understand to properly use. An electronic and optical miracle creates nothing on its own! Whatever beauty and excitement it can represent exist in your mind and spirit to begin with.

We who are gathered here may represent a particular delete, not of money and power, but of concern for the earth for the earth's sake.

The great rocks of Yosemite, expressing qualities of timeless yet intimate grandeur, are the most compelling formations of their kind. We should not casually pass them by, for they are the very heart of the earth speaking to us.

The ‘machine-gun’ approach to photography – by which many negatives are made with the hope that one will be good – is fatal to serious results.

The skies and land are so enormous, and the detail so precise and exquisite that wherever you are you are isolated in a glowing world between the macro and the micro.

I am always surprised when I see several cameras, a gaggle on lenses, filters, meters, et cetera, rattling around in a soft bag with a complement of refuse and dust. Sometimes the professional is the worst offender!
