My first thought is always of light.
I think landscape photography in general is somewhat undervalued.
These days, most nature photographers are deeply committed to the environmental message.
There is no question that photography has played a major role in the environmental movement.
Today, I'm very careful not to mention very specific locations when I write or give captions.
And most of my early pictures failed but about one in a 100 somehow looked better than what I saw.
Wanting to take a light camera with me when I climb or do mountain runs has kept me using exclusively 35 mm.
When we tune in to an especially human way of viewing the landscape powerfully, it resonates with an audience.
A lot of people think that when you have grand scenery, such as you have in Yosemite, that photography must be easy.
I began taking pictures in the natural world to be able to show people what I was experiencing when I climbed and explored in Yosemite in the High Sierra.
