Painting and tracing without a lightbox is like painting on a canvas without an easel. The light box is a translucent surface uniformly backlit by LEDs. It allows you to paint with the highest precision no matter where you are. Illustrators can use the tracing lightbox to color comic strips directly from pencil sketches without the need for tracing or carbon paper.
In addition to being great for drawing and tracing, photographers can also use light boxes to view slides or negatives. Light boxes are also very handy tools for crafts.
