Wow, here's a loaded question. So many answers. Examples in photography, Ansel Adams, Edward Weston, Galen Rowell. Muse, my wife. Gushy, I know, but she makes me feel like I can do anything. I love her. I guess my Inspiration, my divine breath (spiritus) is myself. I got into photography with delusions of grandeur. Now, I must like what I capture or I fell I have wasted something. I suppose it is the legacy of memories I want to leave to those who follow.
