Nature photography seems like such a sincere occupation. A nature photographer can never be a selfish artist because one has to sit in the cold in a wee hut for hours on end to get any results. One has to really love the subject at hand.
For example, Erlend Haarberg:
"The symphony orchestra of the forest is broadening every single day with a new instrument, as the migrating bird species arrive back to their nesting areas and fill the forest with the sound of life. In the dark hours, the hornlike sound of the cranes breaks the silence, and then at 5 o'clock in the morning, nature awakens to the echoing concert of the black grouse, starting suddenly out of nowhere."
