"The close-up abstracts by cutting out the extraneous information through careful framing. You may want to take a close-up photograph of an institutional building to convey monumentality or coldness. With the detail of a gnarled tree you may wish to express delicate sensuality or painful convulsions. A caption (or title) can help direct the viewer to an understanding of your metaphoric intent, but should never become a substitute for it. You should always aim to express the metaphor visually by careful use of exposure, juxtaposition of objects, and lighting.” ― Paul Hill, (Paul Hill, ‘Chapter One: Seeing and Thinking Photographically’, Approaching Photography, 2nd Edition, 2004, Photographers' Institute Press, ISBN 1 86108 323 8, p27)
