Obscura: Known to ancient times, described by greats Mozi, Aristotle, Euclid, al-Kindi and others. Which one is better? LetвЂ™s settle this grudge match by pitting them head-to-head: Camera obscurae also still exist as tourist destinations or curiosities, like the вЂњGiant CameraвЂќ in San Francisco. Contemporary photographers like Abelardo Morell, Shi Guorui, and Vera LutterВ make large obscura images then either photograph their findings or expose the obscura image directly onto light-sensitive paper. But while the camera lucida feel into obscurity, the camera obscura still enjoys moderate popularity. In this version, the artist has now left the dark chamber and works from the outside of the box.ДЄt this point in the mid-19th century, not only had the camera lucida been invented, both lucida and obscura were now joined by the photographic camera.

And it was universally known: MoziВ in China, AristotleВ in Greece, al-KindiВ in the Muslim Arab world all separately remarked on pinhole images. The greatest of ancient minds observed and pondered the effect. The physical and optical principle behind the camera obscura was known in ancient times. (вЂњCameraвЂќ still means вЂњroomвЂќ in Italian, which is why Italians call your point-and-shoot a вЂњmacchina fotograficaвЂќ-photographic machine). This is where we get the word вЂњcameraвЂќ from when referring to the photographic device. The вЂњcameraвЂќ in the name is latin for вЂњchamberвЂќ. By contrast, the camera obscuraВ is an optical device that projects a realtime image through a small pinhole (or lens) into a darkened room. The camera lucidaВ is an optical device which merges an image of a scene and the artistвЂ™s hand on paper for tracing. The camera lucida and camera obscura: whatвЂ™s the difference?
