There are three main factors that control the size of a camera lucida's image: the size of the mirrors, the distance between the drawing surface and the lucida's view hole and factor X.
You could set a lucida ten feet away from the drawing surface and get a huge image, but no one could reach that far to draw. You could increase the size of the mirrors to get a larger image, but then the lucida would be big and bulky.
The LUCID-Art is light, compact and portable, yet you still get a jumbo sized image because we discovered a new way of increasing the size of the image without increasing the size of the mirrors and maximize the size of the image at every height; we call it factor X, but sorry we cannot disclose how it works.
Here are the results, even at its lowest possible height, 16in (41cm) from the drawing surface, you get a large 13in x 26in (33x66cm) image, which is larger than any other camera lucida available--and it just goes up from there. Set at 21in (53.5cm) high the image is 18in x 31in (46x79cm). And at the highest height, 24 ½ in (62cm), you get a mammoth 20in X 37in (51x94cm) image.
