Items in a display or exhibit should present a professional appearance. Mount
all illustrations and photographs. Although not mandatory, consider matting
and framing the work. Arrange the material either chronologically or by a
theme. Pay attention to the way you direct the viewer's line of sight.
Hang material to a common reference point. The four basic reference points
are the vertical or horizontal center line, the flush base or top, the grid
arrangement or a stepped arrangement. Place all material at the eye level of the
average viewer. Leave a large amount of space between each item. Make sure
all presented work is clean and free of defects. Keep the exhibit room quiet,
scrupulously clean, and the room temperature cool.
VERTICAL or HORIZONTAL CENTER LINE: A vertical or horizontal
arrangement of elements is the strongest presentation. Vertical arrangements
are more active than horizontal arrangements. A horizontal center line of an
image is its optical center which is approximately 1/10th above the
mathematical center. Locate the horizontal axis of a horizontal arrangement
approximately 5 1/2 feet from the floor.
Figure 4-1 shows a horizontal arrangement and a vertical arrangement.
