The combination of pictures and words together can be really effective, and I began to realise in my career that unless I wrote my own words, then my message was diluted.

I began to realise that film sees the world differently than the human eye, and that sometimes those differences can make a photograph more powerful than what you actually observed.

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.

I looked at Rembrandt and Superman, Matisse and Bugs Bunny, and began to make my own pictures.

These days, most nature photographers are deeply committed to the environmental message.

My life and career is my own adventure.
