may be frosted mylar or acrylic, or as many photographers have discovered, white plastic shower curtains. The shower curtains are inexpensive, and may be easily hung on a wire, or suspended from the ceiling. The clip-on lights are then located behind the curtains. If you do not have light stands, simply clip the lights onto chair backs. For the back lighting, temporarily tape a section of frosted material over the lamp.

With the indirect method of lighting, as illustrated in Fig. 2, light is bounced off walls or other surfaces to illuminate the object. By "bouncing" the light it is diffused. This is the same technique utilized by professionals, who sometimes use reflective "umbrella" lamps. In fact, the principle of indirect lighting is similar to billiards. Angles must be carefully calculated and the lights arranged respectively, in order to best take advantage of the "bounce" effect. A small room with light colored walls is an ideal setting for this system of lighting.

Be aware however, that any wall color may transfer or reflect some tint to the negatives. Even various shades of white could subtly alter an object's true color, and for this reason it is best to experiment first with some test shots. In fact, when all the variables that can adversely impact on the finished photos are taken into account, these test shots take on added importance. They are an indespensible tool for insuring good quality final photos that accurately and effectively represent your work.

Whichever method of diffused lighting you select, check repeatedly through the viewfinder to ascertain that the object is evenly lighted, without shadow or glare. Considerable adjustment of the lighting may be necessary before this optimal condition is achieved. You should also experiment with the object at various angles and positions. Most pieces look best when they are photographed at an angle and from a slight elevation.

Back lighting is another important aspect of photographing your work. Often a light can be positioned directly behind a piece so it will not be visible. If this is not possible, back lighting may be done from above. Never use a flash unit. Intensity of illumination may be adjusted by moving the lights in tight or further away.

Take at least a dozen shots of each piece from various angles, and when shooting remain absolutely still, since any floor vibration could effect the camera.

For developing and printing your film, it is best to find a local lab with which you can communicate directly. The ability to communicate instructions could mean the difference between average pictures, and pictures that meet your highest expectations.

The equipment mentioned in this feature should be available at your local camera shop. If not, here are two mail order sources for photographic supplies:

Calumet Photographic, Inc.

Arkin Medo, Inc. 131-27 Fowler Avenue Flushing, NY 11355

For those interested in more information about lighting, an excellent book is Techniques of Photographic Lighting, by Norman Kerr. W\\j
