Beginning artists often relay on tracing, or copying the outline of an image onto a print medium, while learning painting techniques. A tracer projector and enlarger facilitates the tracing process.

A tracer projector and enlarger is a device that projects images, such as original artwork on film, onto a flat surface such as a screen or canvas. The tracer projector and enlarger also magnifies the image to facilitate tracing and allow it to translate better onto the larger surface.


The tracer projector and enlarger shines a light, via a wattage-powered bulb, through an optical lens, which converges the light beam onto the image. The lens, fitted with an aperture, or opening through which light travels, can adjust the ratio of distance from the film to the optical lens to acquire various degrees of enlargement.


Standard tracer projectors and enlargers allow a copy size of 5x5; offers a projection range between two and fourteen times and a black-and-white or colour projection option. Tracer projectors and enlargers receive wattage via a cable that plugs into a standard outlet.
