Now to consult the rules of composition before making a picture is a little like consulting the law of gravitation before going for a walk. Such rules and laws are deduced from the accomplished fact; they are the products of reflection.
现在,在照相之前先研究构图的规则,有点像在散步之前先研究万有引力定律。这些规则和规律是从既成事实中推导出来的;它们是反思的产物。
