A light box[light box?:light box] consists of a backlit piece of plexiglass or frosted glass. Many visual artists use light boxes in their daily work for things like looking at photographic negatives and tracing.
Another term for a light box is a light table. Usually, a light box is distinguished from a light table because it is much more portable and it lacks legs. In some cases, a light box can be very large, making it technically difficult to move, while in other instances a light box may be designed around a lightweight briefcase or tablet so that it can easily be ported from place to place. A light box tends to be substantially less expensive than a light table, since it does not have a complex framework of legs.
The placement of the lights in a light box is very important. The goal is to achieve even, crisp lighting without hot spots. The glass or plexiglass is usually fogged or shaded to reduce glare from the lights underneath. The whole assembly of the light box is enclosed in a sturdy frame, which often features drawers or divots for storing tools.
