Eastman Kodak’s Slow-Developing Bankruptcy Moment (New York Magazine)
Eastman Kodak is bankrupt, and nobody should be surprised. The company that
more or less invented photographic film and once controlled 90 percent of the
market knew the digital revolution was coming. In fact, one of its own
employees, a guy named Steve Sasson, invented the digital camera in 1975, and
correctly calculated that it would be a marketable product in about twenty
years.
Yet when digital finally swept in, it happened fast, and Kodak as a company
had always been sluggish to embrace change. (In the mid-twentieth century, it
took Big Yellow twenty years to realize that a little company called Polaroid
had carved off a big chunk of the amateur-photo market.) Kodak couldn't simply
shift to making digital cameras, because that's a much lower-margin business
than film, and companies that were better at electronics (Sony, Canon, Nikon)
were going to eat Kodak's lunch anyway. Its executives kept casting about to
find areas where its expertise could dominate -- chemicals, cleaners, online
photo-sharing. Nothing took off. The latest effort is inkjet printing, where
Kodak thinks it can succeed by underpricing its competition, and one hopes
it's right. We all hate paying $30 for Hewlett-Packard ink ...
First Impressions: Canon Powershot ELPH 300 HS
A digital camera is basically a digital device that enables images to be captured. by Nicholson
A digital camera is basically a digital device that enables images to be captured. Digital camera images are stored electronically rather than on film. This process involves converting light into electrical charges, and then translating this back into the image that was seen through the digital camera LCD. Although the digital camera is a recent addition to the world of photography, the concept of the possibility of a digital camera was begun in the 1950s.
The early concept of the digital camera was closely linked to television technology. It began with digital images being recorded on scanners and in the form of digital video signals. In 1951 broadcasting companies were recording images as electrical impulses and onto magnetic tape from their television cameras, and this paved the way for digital camera technology to begin. By 1956 electrical impulse recordings were common practise within film industry, and camera manufacturers began to dream of a digital camera device.
The first record of a patent for a type of digital camera was in 1972 when Texas Instruments patented a camera that did not require film. However, the patent revealed a more analog based design rather than a digital camera, and there is no record of whether the camera was actually created. What the patent does show, however, is that interest towards a digital camera was growing with the idea that the need for film could be removed. A pioneer in the history of digital camera was Steve Sasson, an engineer at Kodak. Digital images were of the moon were being transmitted via satellite by NASA, using a mosaic photo sensor, and he saw the possibility of a digital camera for commercial use. In 1972 he began to group together available equipment used within the film industry to create an image digitally rather than on film.
Central to this early concept of the digital camera, and still used by digital cameras today, is the Charged Coupled Device. The CCD detects light and colour intensity and then converts this information into electrons. The value of each cell in the image is then read, and converted to binary format to make the image computer compatible. Steve Sasson produced his first digital camera image in 1979. The image took a total of 23 seconds to take, and a further 23 seconds to read from the playback unit. Although the digital camera image was less than perfect, it showed that the digital camera was a possibility. Kodak had developed a camera that developed picture from light, but it was never manufactured for the public.
The first camera to be marketed was the Sony Mavica electronic still camera in 1981. It was not a true digital camera as the image was recorded on mini disc, and then attached to a television or video. It was more a freeze frame video camera but it greatly influenced people's attitude to the recorded image. It made public the possibility of a camera that stored images using techniques other than film. It still used more television technology but was the first hand held with the general idea of digital camera usage. Cameras that could transmit images via satellite became popular, but were used by the media only due to the expense incurred. The possibilities were becoming apparent and images were used for news coverage. The first camera for general use with a computer was the Apple Quicktake 100 camera which appeared in1984. In 1986 the Canon RC-701 was used for coverage of the Olympics, with quality images printed in the newspaper. This showed the possible quality, and the desire for the digital camera was born.
The first mega pixel sensor was invented in 1986. It contained 1.4 million pixels and was suitable for a digital camera image measuring 5x7 inches. In 1987 accessories for storing, printing, manipulating, transmitting, and recording digital images came onto the market, with the Fuji DS-P1 arriving in 1988. This is arguably the first true digital camera as recognised today, boasting a 16MB memory card. With the arrival of JPEG and MPEG standards in the 1990's, the face of the digital camera was changed for ever. Kodak marketed the first readily available digital camera that met all standards, with the Kodak DC40 in 1995.
