Summary
[edit]| Description |
English: View through a camera lucida. The image of the drawing hand is real, the image of the candles is virtual. The image here is near perfect and was realized by illuminating the scene, in a darkend room.
A camera lucida is an optical device used as a drawing aid by artists. The camera lucida performs an optical superimposition of the subject being viewed upon the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure. This allows the artist to duplicate key points of the scene on the drawing surface, thus aiding in the accurate rendering of perspective. At times, the artist can even trace the outlines of objects.Nederlands: Beeld verkregen door een camera lucida. Het beeld hier is uitzonderlijk scherp omdat de scene fel verlicht werd in een verduisterd lokaal.
Een camera lucida was een instrument bestaande uit een verstelbare stang, die met een klem aan de tekentafel werd vastgemaakt. Aan de bovenzijde was een in metaal gevat prisma bevestigd. Door dit prisma juist af te stellen, werd in de gewenste afmetingen het tafereel of het object op tekenpapier geprojecteerd. Het apparaat was vooral in de achttiende eeuw in omloop. |
