Welcome to my world!

Photographing in the redwoods usually means exposures of 15 seconds to 30 minutes. One's hair on arms and legs (I usually wear shorts) become hypersenstitive wind meters!

Mid-day, as the down slope winds reverse themselves and become up canyon winds, one can often sneak in a photo or two during the stillness of the change.
