Pinhole Camera
The first photographic equipment was the pinhole camera. It
is a simple camera/box/chamber (light=proof box) without a lens but with a tiny
aperture/opening. Invented in the 10th century, by Ibn al-Haitham (Egyptian
Scientist). Here the Light
from a scene passes through the aperture and projects an inverted image on the
opposite side of the box, which is known as the camera obscura effect.
Camera Obscura
A pinhole camera with a lens for its tiny opening. Artists
used it to get the shape and proportion of images right. Scientists kept
discovering and using better optics and lenses to manipulate the image. Images
kept improving, but not able to retain images permanently.
First Recorded, and Surviving Photograph
The First Photograph |
The first recorded Heliograph (photograph) was by Nicéphore Niépce (1826), France. The exposure took about 8 hours. He used a chemically coated metal plate to capture and retain the image. In 1833, Louis Daguerre also used a metal plate but with reduced exposure time, called, the Daguerreotype. It took about half an hour for exposure. It was William Fox Talbot who first used translucent negative for capturing and retaining the image in 1835, and in 1841 he got it patented. It was called Talbotype/Calotype. It first produced the camera negative, and from it a positive image could subsequently be printed, and make many copies. Talbot’s negative-positive process dominated photography up to the digital age.
In 1888,
Kodak commercial cameras came in market, with dry, transparent, flexible
photographic film that came in a roll. It was invented by invented by George Eastman. Polaroid Instant Image Camera made its
appearance in 1848. It was discovered by Edwin H. Land.
