“What the newer landscape artists see in a circle of a hundred degrees in Nature they press together unmercifully into an angle of vision of only forty-five degrees. And furthermore, what is in Nature separated by large spaces, is compressed into a cramped space and overfills and oversatiates the eye, creating an unfavorable and disquieting effect on the viewer.”
