In the aftermath of the 1906 San Francisco earthquake and fire , and the income from his photos , Pillsbury , who had just quit his job with the '' San Francisco Examiner '' to found the Pillsbury Picture Company , was able to fulfill his long-time ambition to buy a studio in Yosemite and purchased the Studio of the Three Arrows later that same year . His background in biology and botany , encouraged by his parents who were both medical doctors , made him aware of the steady reduction in the number and types of wild flowers that blossomed in the meadows there . So in 1912 he built the first lapse-time camera , made the first nature movie showing the dance of a flower raising its face to the sun and managed to persuade the National Park Service to stop the practice of mowing the meadows to produce fodder for their horses
