How does a camera works and who invented it when and how?
Go into a very dark room on a bright sunny day. Now make a small hole in a window cover and look at the wall opposite to that window. You would see magic! You would see everything outside the window, just turned upside down!
This magic is however nothing but simple science. All of you know that light travels in a straight line. Now what happens is that when some of the rays reflected from a bright object pass through a small hole, instead of scattering apart, they reform as an upside down image on a flat surface opposite to the hole.History of the Camera Camera Obscura History
The earliest mention of this type of device was by the Chinese philosopher Mozi in 400 B.C. He is said to have created the first inverted image formed by light rays passing through a pinhole into a darkened room.
The camera obscura was a device working on this principle, consisting of a room or a box with a hole on one side. The first camera obscuras were large rooms and were used for observing a solar eclipse.
The first portable camera obscura was built by Irish scientist Robert Boyle and his assistant Robert Hooke in the 1660s.The First Photograph
The first photograph was taken in 1827 by a man named Joseph Niépce. However, the image required eight hours of light exposure and later faded. A few years later, a Frenchman, Louis Daguerre, partnered with Joseph Niépce and developed the process of creating permanent photographs known as Daguerreotype, in 1829.
