The images of nature in general express a need for immediacy and are not subject to conventions, rules, or technical specifications. They are something at once instinctive and concealed. Natural beauty is indeterminate and indefinable. The meeting of day and night, light and darkness, the seasons in the form of atmospheric conditions, creates a kaleidoscopic play of sensations that pleasantly overcomes us. The wonder of seeing and feeling is born of the sense of surprise.
