History of the Camera

!±8± History of the Camera

Early cameras of the 16th and 17th century were able to task images onto paper or glass but the study of capturing, processing and printing the images took many more years. Up until the 17th century, scientists believed that light was composed basically of the 'white' that is perceived by the human eye. It took the explore done by illustrious physicist Isaac Newton to gawk that light is for real composed of a spectrum of colors. While he made a big offering to the study of optics (that is at the core of camera advances) with this discovery, Newton did not for real have anyone to do with camera amelioration per se.

The early camera that first became a phenomenon was a dinky more than a pinhole camera and can be traced back to 1558. It was called the Camera Obscura. The Camera Obscura was seen as a drawing tool for a clearer and realistic portrayal of objects. It was in the early 19th century that an invention named the Camera Lucida was introduced by Cambridge scientist William Hyde Wollaston that consisted of an optic gadget that could help an artist view a distant scene or man or object on a paper surface that he or she was using to draw. In other words the artist gets to view a superimposed image of a subject on paper and this image could be effectively used to attempt to draw, trace or paint it. Both the Camera Obscura and the Camera Lucida in case,granted an image that was temporary, which could not be lastingly captured on to paper for later reference.

Studies any way prolonged well into the 1800's on how to for real capture the image onto material. It was while this time, nearby 1822 that French researcher Joseph Nicephore Niepce, created the first photograph by using paper that was coated with a chemical. The image would not stay permanently on the paper and would disappear after a short while. Even so, despite the short-lived nature of the image, the belief of photography was born with this experiment and paved the way for additional study and amelioration in this field.

Capturing images to support them longer and permanently became the next big quest for researchers. Someone else Frenchman Louis-Jacques-Mandé Daguerre partnered with Joseph Nicéphore Niépce in 1829, to form the process of creating permanent photographs. Joseph Niépce died in 1833 but Daguerre prolonged with the work and succeeded in 1837 after many long years of experimentation. The process of capturing photographic images that would not fade away, introduced by Daguerre came to be known as the 'daguerreotype'.

The word 'photography' was coined by scientist Sir John F.W. Herschel in 1839 and it is for real is derived from two Greek words 'photos' meaning light and 'graphein' meaning draw.

A slightly more advanced version of the daguerreotype called the Calotype process that makes manifold copies potential using the negative and confident formula became available very soon after. In fact, it was while the 1840's that the use of photographic images in advertisements first started and cameras made their mark on the power of optic communication. It was not much later, in the 1850's that photographers first started experimenting with underwater photography of seascapes.

Up until 1850, the process of capturing images was cumbersome requiring upto half an hour of light exposure. The discovery made in 1851 by Frederick Scott Archer was a blessing since the new formula termed the Collodion process called for just 2-3 seconds of light exposure to capture an image.

Prior to 1871, photographers went through a amelioration process where they had to coat the plate with wet chemical each and every time and process the image immediately. With the invention the gelatin dry plate silver bromide process by Richard Leach Maddox, negatives did not have to be advanced immediately. This was an foremost discovery since up until then the captured image had to be processed instantly.

Kodak created in 1888 by George Eastman has been a contemporary day pioneer of sorts in cameras and photography for the masses. George Eastman and the scientists who worked with him at Kodak advanced the photographic film in 1889 and made it available in rolls for the mass use of consumers. An foremost milestone in our entertainment and communication history was the amelioration of transparent roll film by Eastman. This amelioration led to Someone else key invention - the motion photograph camera by Thomas Edison's in 1891.

-->Modern Times

During the 20th century the pace of technology amelioration in cameras and photography prolonged at an accelerated pace much like many other key technology developments. While some key inventions like car, telephone and the gramophone article happened in the later half of the 19th century, it is the last 100 years that saw major developmental work in many areas of communications technology and as well as in other fields - Tv, aircrafts, Pcs, digital technology, digital cameras, mobile phones, fax machines and the internet, to name a few.

In the case of the camera, the developments simplified the whole process of photography, manufacture it accessible to one and all at affordable prices and the camera business denizens of our times made it into a mass phenomenon. The first mass use camera became available at the turn of the 20th century and can be traced back to the year 1900. There are hundreds of models of cameras available today both for the amateur as well as the professional and the camera is an foremost part of any family's repertoire of must have gadgets.

-->20th century chronology in the history of the camera:

1913: 35 mm still-camera created

1927: The flash bulb introduced by normal galvanic Co. (The belief of camera flash existed much before but was based on the use of a flash light powder that was invented by German researchers)

1935- 1941: Kodak starts marketing Kodachrome film and subsequently launches Kodacolor negative film. Canon released the Hansa Canon in 1936, the first 35mm focal-plane shutter camera.

1948: The belief of the Polaroid camera is introduced in the market. American scientist Edwin Land advanced the process for instant photography. Later Polaroid Corporation advanced the 'instant color' film nearby 1963.

1957: Frenchman Jaques Yves Cousteau invented the first waterproof 35mm camera for underwater photography named the Calypso Phot. The actual camera was advanced by the Belgian airplane technical designer Jean de Wouters based on the blueprint and suggestions given to him by Cousteau.

1972: The electronic camera that does not wish film was created and patented by Texas Instruments. This is any way not the same as a digital camera though you don't wish film in digital cameras as well. The embark on of the digital camera is still many years away.

1975: Kodak's experiments with digital imaging kicked off nearby the mid seventies but it will take Someone else 20 years before a digital camera for the home buyer market is launched.

1978 - 1980: Asian players like Konica and Sony begin to make their mark. The 'point and shoot' self-operating focus camera is launched by Konica while Sony starts talking about the camcorder and demonstrates a prototype.

1981: Sony launches a commercially available electronic still camera. Similar to the 1972 invention by Texas Instruments, the Sony electronic camera came with a mini disc on which images were recorded and stored. The recorded images could be later printed or viewed on a monitor using a reader device.

1985: Digital processing technology makes its entry. Digital imaging and processing is introduced by Pixar.

1986: The camera business becomes even more buyer focused and taps the fun and trip connotations behind camera usage, with the embark on of the belief of the disposable single use cameras. Fuji is credited with the amelioration of this concept.

Also in 1986 - 1987, Kodak started taking giant strides in digital development. Digital means, the photographic image is divided into tiny units of dots or squares known as pixels. Pixels are the programmable units of an image that can be processed by computers. Each image could be made up of millions of pixels. The use of pixels in digital technology allows storing large volumes of pixels to deliver high definition print quality.

1990: Kodak introduces Photo Cd's. It is a law of storing photographic images on Cd and then viewing them on a computer. With this amelioration the user-friendly coming of the camera business began to take concrete shape.

1991: Kodak introduces a digital camera targeted at professionals and journalists. Kodak is credited with the invention of a pixel based camera technology known to us as the digital camera. Digital cameras don't use film similar to their predecessor electronic cameras but the storehouse formula is entirely dissimilar and the final photograph is of much higher resolution. In a digital camera photos are recorded and stored in digital form. This digital data can be transferred to a computer and processed for printing. Kodak and Canon are well known digital camera manufacturers and there are also some other key brands as well.

1994: The Apple QuickTake camera, a home use digital camera is launched. This is followed by the embark on of a clutch of home use digital cameras by Casio, Kodak and others in quick succession while 1995 -'96.

-->The digital era:

The amelioration of digital camera technology is thought about to be connected to the amelioration of Tv and Video technology. The law of transmission and recording of audio-visual images using digital electrical impulses finds use in camera imaging as well.

Through the 1990's the developments prolonged in camera technology, the focus now shifting to the field of digital imaging which is where the future lies. Use-friendly features like software that can download digital images directly from camera onto home computers for storing and sharing on the internet is the new norm in the market place.

The camera, the computer, the software business and the worldwide web are today irrevocably interlinked to empower the user in experiencing the benefits of camera usage to full potential. The innovation that sparked many an invention in the camera business found its way into the digital world as well and prolonged among digital camera manufacturers. while 2001, the Kodak and Microsoft partnership ensured that digital camera manufacturers could use the power of photograph replacement Protocol (Ptp) proper through Windows. The digital photo perceive is a key optic driver in the Internet era. Many of Kodak digital camera models with EasyShare capabilities are compatible with Windows Xp. The Kodak EasyShare software enables users to replacement digital camera pictures directly from camera to their computers and then print the pictures or even email them.

Manufacturers in a connected business like the printing business have adapted their products to be in sync with the images created by digital cameras. Cell phone manufacturers have tied up with digital camera manufacturers to form new age camera phones in modern years. These camera phones can capture images and share the images through the cell phone.

Among the 21st century digital developments are the advanced product offerings from digital cameras manufacturers and these are sure to occupy an foremost place in the ensuing history of camera development. For instance, the Kodak professional Dcs Pro Slr/c is a high-end digital camera and the Kodak website calls the Dcs Pro Slr models the most feature-rich digital cameras on the market. It has an image sensor that can cope 13.89 million pixels and this makes it the top resolution digital camera available. High resolution determines the sharpness or level of information in photographic images. This is just a sight of the capabilities that digital technology places in a user's hands. Digital camera sales figures for 2003 show that the two key players Kodak and Canon have recorded impressive growth.

-->What does the future holds for camera users?

The features offered by digital cameras can be quite mind-boggling for the median user and pretty challenging for most pros. Four key ongoing camera developments that are likely to additional heighten the process of photography:

1. Greater resolution from even the simplest, low cost camera models

2. Usage in any type of lighting conditions,

3. Compatibility across a range of software, hardware and image types

4. Rich colors and tone

While the higher-end digital evolution continues, the prices of the straightforward camera have crashed to such an extent that even children and teens are proud owners of straightforward cameras. The camera and photography interest starts young and this creates a truly large audience base for the camera industry.

And throughout history, it is clear that the attempt of researchers and developers has been to make the camera available to a wide section of society. Without camera technology and photography, the other key developments of cinema and Tv would have been delayed and what a boring place the world would have been without Tv and films!!
