Camera Lucidas

People who take interest in camera and camera history might know or like to know about the camera lucida. This was an optical tool patented in 1806 by William Hyde Wollaston for use as a drawing support amongst artists. It was a shimmering prism that helped artists to sketch outlines in accurate angle. There was no need of the darkroom and the paper was laid flat on the drawing board, and the artist should look around a lens having the prism, so that he might watch both the paper and a faint picture of the subject to be drawn. He might next fill in the figure. On the other hand, as anyone who has tried using these would be familiar only too well, that too needed artistic expertise as Fox Talbot also revealed. Whilst it looks that this was just an imitation of a tool just about two hundred years prior by Johannes Kepler, the loss of Kepler’s information left doubt and room for Wollaston to get involved and patent the device.

The main scheme of the camera lucida is to superimpose the matter being watched optically onto the surface where the artist is drawing. In simplest type, the artist would gaze down at the drawing surface through a half-silvered mirror angled at forty five degrees, superimposing a direct vision of the drawing under the surface and a reflected view of a picture horizontally in front of the artist. A feeble negative lens makes a virtual image of the scene about the similar distance as the drawing surface, permitting both to be watched in good focus at the same time. For the reason that the artist may watch the scene around the individual in addition to the drawing surface, it is much similar to a photographic double exposure.

Now the artist has the skill to transport a variety of points of recognition from the scene to the drawing surface, creating the drawing more precise and correct in terms of viewpoint. In actual fact, the artist has the alternative of just tracing the objects within the scene must he or she so wish. Due to a washout experience happening with white paper, a lot of users have in the history selected to work with black paper and a white pencil.
