1) GO TO A PROFESSIONAL. All piercings should be carried out by professionals â including the common ear lobe piercings â but it is especially important that cartilage piercings, and piercings on other sensitive body parts are carried out by trained professionals who do such piercings for a living.
Camera obscura is Latin for dark chamber.. It is the name given to a simple device used to produce images that would lead to the invention of photography. The English word for today's photographic devices is merely a shortening of this name to  camera .
The term camera obscura was first used by the German astronomer Johannes Kepler in the early 17th century. He used it for astronomical applications and had a portable tent camera for surveying in Upper Austria. The development of the camera obscura took two tracks. One of these led to the portable box device that was a drawing tool. In the 17th and 18th century many artists were aided by the use of the camera obscura. Jan Vermeer, Canaletto, Guardi, and Paul Sandby are representative of this group.
