Career Ponti opened an optician’s shop in Piazza San Marco 52, near the Caffè Florian, producing high quality instruments, for which he had sole rights, for astronomy and physics and photographic lenses, especially those used for panoramas, as well as selling products of other companies. On 30 May 1854 he was awarded a silver medal for his photographic equipment at the Esposizione Industriale Veneta. As a photographer and editor Ponti published photographic prints, both his own and others, building an international clientele. From this time he systematically photog ...

Depth Perception
Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions. Depth perception happens primarily due to stereopsis and accommodation of the eye. Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. Depth perception arises from a variety of depth cues. These are typically classified into binocular cues and monocular cues. Binocular cues are based on the receipt of sensory information in three dimensions from both eyes and monocular cues can be observed with just one eye. Binocular cues include retinal disparity, which exploits parallax and vergence. Stereopsis is made possible with binocular vision. Monocular cues include relative size (distant objects subtend smaller visual angles than near obj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
