A toy trace projector is actually not a bad investment for an artist if their enlargements are not too extensive. The inexpensive cost and easy-to-use features of the projector make it simple to operate. The case on the projector is also designed to be durable enough for rough handling. In a busy art room, space is often a premium and occasionally items are knocked over during the bustle of completing a project.
A standard artist variety trace projector will allow enlargements up to 20 times and is usually capable of receiving images from USB ports and sometimes directly from phones. This gives you great flexibility in the size of your image file and how to transfer the best version of that image to the device. The better the beginning image, the better quality the enlargement. The projector also has a lens which allows you to sharpen and focus the image so the details you want are sharp and clean.
Professional trace projectors are designed to work equally well across a variety of formats. Other features are available, including different lenses and enlargement and reduction capacities. Some models are suggested for particular types of work, such as watercolors or leather crafting. Usually, the store will allow you to compare models side-by-side to see the variations and features in order to assist you in selecting the right projector for your work.
Trace projectors are used to enlarge images and project the enlargement on a larger surface so it can be reproduced. It is also used for composition where more than one image can be combined to create a unique third image. Projected color photographs allow the artist to color correct portraits on the spot. The projector can be moved to duplicate a shape similar to using an outline and a drawing can be corrected by overlaying the original image forms.
