Cognition: the Limit to Organization Change; a Case Study of Eastman Kodak
COGNITION: THE LIMIT TO ORGANIZATION CHANGE; A CASE STUDY OF EASTMAN KODAK A THESIS Presented to The Faculty of the Department of Economics and Business The Colorado College In Partial Fulfillment of the Requirements for the Degree Bachelor of Arts By Noah Simon April 2011 COGNITION: THE LIMIT TO ORGANIZATION CHANGE; A CASE STUDY OF EASTMAN KODAK Noah Simon April 2011 LAS: Leadership Abstract The following thesis examines an incumbent firm affected by change. It seeks to deepen the understanding of the dynamic capabilities model by proposing cognition and not previous resource deployment is the limit of change. Two similar companies, Eastman Kodak and Polaroid will be compared during the shift from film to digital photography to determine what separated the two companies.

KODAK MILESTONES 1879 - Eastman Invented an Emulsion-Coating Machine Which Enabled Him to Mass- Produce Photographic Dry Plates
KODAK MILESTONES 1879 - Eastman invented an emulsion-coating machine which enabled him to mass- produce photographic dry plates. 1880 - Eastman began commercial production of dry plates in a rented loft of a building in Rochester, N.Y. 1881 - In January, Eastman and Henry A. Strong (a family friend and buggy-whip manufacturer) formed a partnership known as the Eastman Dry Plate Company. ♦ In September, Eastman quit his job as a bank clerk to devote his full time to the business. 1883 - The Eastman Dry Plate Company completed transfer of operations to a four- story building at what is now 343 State Street, Rochester, NY, the company's worldwide headquarters. 1884 - The business was changed from a partnership to a $200,000 corporation with 14 shareowners when the Eastman Dry Plate and Film Company was formed. ♦ EASTMAN Negative Paper was introduced. ♦ Eastman and William H. Walker, an associate, invented a roll holder for negative papers. 1885 - EASTMAN American Film was introduced - the first transparent photographic "film" as we know it today. ♦ The company opened a wholesale office in London, England. 1886 - George Eastman became one of the first American industrialists to employ a full- time research scientist to aid in the commercialization of a flexible, transparent film base. 1888 - The name "Kodak" was born and the KODAK camera was placed on the market, with the slogan, "You press the button - we do the rest." This was the birth of snapshot photography, as millions of amateur picture-takers know it today. 1889 - The first commercial transparent roll film, perfected by Eastman and his research chemist, was put on the market. -

“Dark Chamber”
The Word Camera Is From Latin “Camera Obscura” Which Means “Dark Chamber”. National Camera Day is observed each year on June 29th. This day commemorates photographs, the camera, and their invention. A camera is an irreplaceable tool used to record and replicate memories, events, and people/places. Before the invention of the camera, the only resource to document a vision was a painting. There are very few who can perfectly capture the image of a person or a place in a drawing. The power of a camera provided many with a simple, inexpensive and fast solution. George Eastman, also known as “The Father of Photography,” brought the camera to the masses. While he did not invent the camera, he did invent many additions that improved the use, ease, and production of the camera, making it widely available to homes around the world. The original camera was large and bulky but has now evolved into something that can be as small as a pen. Cameras have many features and variations, making them appealing to men and women of all ages for personal and professional use. Joseph Niépce was a French inventor; he is most noted as one of the inventors of photography and was a pioneer in the field. He developed the heliograph; a technique used to produce the world’s first known photograph in 1825, the view from the window at Le Gras the families estate. In 1839, Louis Jacques Daguerre took the first fixed image that didn’t fade. He is recognized for his invention of the daguerreotype process of photography. -

What Is a DSLR (Digital SLR)? DSLR Stands for “Digital Single Lens Reflex”
Camera Basics, Principles and Practices Course Code MCD 401 What is a DSLR (Digital SLR)? DSLR stands for “Digital Single Lens Reflex”. In simple language, DSLR is a digital camera that uses mirrors to direct light from the lens to the viewfinder, which is a hole on the back of the camera that you look through to see what you are taking a picture of. 1) What do DSLR cameras consist of? Take a look at the following image of an SLR cross section (image courtesy of Wikipedia): Lens Reflex mirror Shutter Image sensor Matte focusing screen Condenser lens Pentaprism Eyepiece/Viewfinder 2) How do DSLR cameras work? When you look through the viewfinder on the back of the camera, whatever you see is exactly what you are going to get in the photograph. The scene that you are taking a picture of passes through the lens in a form of light into a reflex mirror (#2) that sits at a 45 degree angle inside the camera chamber, which then forwards the light vertically to an optical element called a “pentaprism” (#7). The pentaprism then converts the vertical light to horizontal by redirecting the light through two separate mirrors, right into the viewfinder (#8). When you take a picture, the reflex mirror (#2) swings upwards, blocking the vertical pathway and letting the light directly through. Then, the shutter (#3) opens up and the light reaches the image sensor (#4). The shutter (#3) remains open for as long as needed for the image sensor (#4) to record the image, then the shutter (#3) closes and the reflex mirror (#2) drops back to the 45 degree angle to continue redirecting the light into the viewfinder. -
History of Photography
History of Photography ancient times: Camera obscuras used to form images on walls in darkened rooms; image formation via a pinhole 16th century: Brightness and clarity of camera obscuras improved by enlarging the hole inserting a telescope lens 17th century: Camera obscuras in frequent use by artists and made portable. 1727: Professor J. Schulze mixes chalk, nitric acid, and silver in a flask; notices darkening on side of flask exposed to sunlight. Accidental creation of the first photo-sensitive compound. 1800: Thomas Wedgwood makes "sun pictures" by placing opaque objects on leather treated with silver nitrate; resulting images deteriorated rapidly, however, if displayed under light stronger than from candles. 1816: Nicéphore Niépce combines the camera obscura with photosensitive paper 1826: Niépce creates a permanent image View from Niepce’s Window at Le Gras. 1834: Henry Fox Talbot creates permanent (negative) images using paper soaked in silver chloride and fixed with a salt solution. Talbot created positive images by contact printing onto another sheet of paper. 1837: Louis Daguerre creates images on silver-plated copper, coated with silver iodide and "developed" with warmed mercury; Daguerre is awarded a state pension by the French government in exchange for publication of methods and the rights by other French citizens to use the Daguerreotype process. 1841: Talbot patents his process under the name "calotype". Known also as “Tintypes” 1846 Associated Press 1851: Frederick Scott Archer, a sculptor in London, improves photographic resolution by spreading a mixture of collodion (nitrated cotton dissolved in ether and alcohol) and chemicals on sheets of glass. Wet plate collodion photography was much cheaper than daguerreotypes, the negative/positive process permitted unlimited reproductions, and the process was published but not patented. -
