Who invented the photographic invention daguerreotype?
The Daguerreotype was supposedly invented by a Frenchman named Louis Daguerre. He may have stolen the idea from his partner, Nicephore Niepce who invented the heliograph and the first permanent camera photograph in 1826. As an aside, Daguerre's name is one of the 72 names inscribed on the Eiffel tower. ...

Did Thomas Edison invent photography?
No Thomas Edison did not invent photography. Employing data from the researches of Johann Heinrich Schulze-who, in 1727, discovered that silver nitrate darkened upon exposure to light-Thomas Wedgwood and Sir Humphry Davy, early in the 19th cent., created what we now call photograms. The French physicist, Joseph Nicéphore Niepce, made the first negative (on paper) in 1816 and the first known photograph (on metal; he called it a heliograph) in 1826. ...

How long did the Camera Obscura take to develop the first picture?
Call me a nit-picker, but the camera obscura was not really a camera in the sense that it was not invented for the purpose of making photographs, and cameras don't develop pictures. If you're asking how long it took to make the first permanent exposure, it was about 8 hours. That being said, the camera obscura was used to make the first permanent photographic image (an image taken in nature). The first permanent image was a reproduction of an engraving and was...
What is meant by the culture of telecommunication?
telecommunication is the assisted transmission over a distance for the purpose of communication. In earlier times, this may have involved the use of smoke signals, drums, semaphore, flags or heliograph. In modern times, telecommunication typically involves the use of electronic devices such as the telephone, television, radio or computer. Early inventors in the field of telecommunication include Alexander Graham Bell, Guglielmo Marconi and John Logie Baird. Telecommunication is an important part of the world economy and the telecommunication industry's revenue was estimated to be...

What signaling device was named after the sun god Helios?
The instrument is called a Heliograph. It reflects sunlight to a remote station and is used in signaling and surveying by reflecting and then blocking the sunlight to create flashes of light, a bit like morse code but without the sound. The communication itself is called a Heilogram. This device was used primarily by the military in the 19th and early 20th century. It was invented by Sir Henry Christopher Mance (1840-1926) of the British Army Signal Corps in 1869, and was...

What is heliography?
Quoted from Wikipedia: Heliography (in French, héliographie) is the photographic process invented by Joseph Nicéphore Niépce around 1825, and which he used to make the earliest known permanent photograph from nature, View from the Window at Le Gras (c. 1826). The process used bitumen, as a coating on glass or metal, which hardened in relation to exposure to light. When the plate was washed with oil of lavender, only the hardened image area remained. The word has also been used to refer to...

What was the first world's photo?
Joseph Nicéphore Niépce is credited with producing the world's first photograph, a picture of buildings visible from the rooftop of his home made sometime in the summer of 1827. (It should be noted that some scholars suspect that the Shroud of Turin may be a photographic image, but if it is, it probably was not intentional. Niépce's image certainly was intentional.) The photograph is not much to look at, since the exposure lasted all day and the shadows swept across the whole scene...
