Its solid-fuel rocket motor was prepared from nitrocellulose. He reached for the nearest cloth, a cotton apron, and wiped it up. He hung the apron on the stove door to dry, and, as soon as it was dry, there was a flash as the apron ignited. His preparation method was the first to be widely imitated—one part of fine cotton wool to be immersed in 15 parts of an equal blend of sulfuric and nitric acids. After two minutes, the cotton was removed and washed in cold water to set the esterification level and remove all acid residue. By coincidence, a third chemist, the Brunswick professor F.

I recently had a very unproductive E-mail exchange with Kodak in regards to their printers default behavior to disable my printer as soon a low ink notification shows up. Any chance anyone knows how they monitor the ink level in the ESP series , or even more importantly, how to override it, so I can continue to print until the cartridge is actually empty?

Resetting the cartridge counter [if one has a defective chip or a manually refilled cartridge]: Apparently,it is a circuit that carries the count of pages printed to a counter. The instructions I read were to ‘insert the blade under the line. I had to do it in daylight; you may have better eyes.

There are several different lists of Kodak movie film date codes published, and one of these appears to be correct for 35mm and mm still camera film, both safety and nitrate. I have reviewed numerous versions of this list and checked them against factory records and internal correspondence dating back to .

Phoenix Indian Shool band, postcard ca From the collection of Jeremy Rowe, Mesa, Arizona. This photographic campaign dovetailed perfectly with the documentary project of Edward S. Curtis who, like many earlier “ethnographic documentation” projects, injected editorial control by adding or modifying the costumes and props that appear in the images.

Curtis called photography an “art-science” defining a role of the documentary photographer that went beyond notions that photographs were “documents” in the sense of “objective representations of what his subjects were” [Lyman, Curtis selected subjects that seemed to him to be noble primitives and carefully posed them to reinforce that perception. From time to time Curtis manufactured costumes or dressed his subjects in"Indian” clothes that he carried around in a trunk; he used scrims and tents, depth of field and framing to eliminate signs of modern life from his shots; he similarly retouched, cropped, and manipulated images in the dark room Lyman The close analysis of Curtis’s photographs performed by Christopher Lyman, demonstrates how he consciously created a vision of the"untutored savage” and a"vanishing race.

This is a dedicated thread placed here so it is easier to find based upon the discussion from here. The following data was archived from Thomas Robinson’s website which is here. This information is useful to determine the date the film was slit. This is the point of manufacture where the large sheets of raw film are cut and perforated. These date codes are imprinted at that time. Most film, especially color, was exposed and developed within a few years of this date.

The Kodak Medalist was an unusual design for a medium format camera when it was introduced in Most rollfilm cameras of this vintage were folders, similar to the Kodak Tourist shown in this site. The Medalist, however, was a rigid cast-aluminum body design with a unique double helical lens tube in place of the conventional cloth bellows.

Never for instantaneous exposures. For or"Time” exposures outdoors in cloudy weather. The smaller the stop the sharper the picture. Absolute failure will be the result if you use the smallest stop for instantaneous exposures. Flash-Light Pictures By the introduction of Eastman Flash Sheets, picture taking at night has been wonderfully simplified.

A package of flash sheets, a piece of cardboard, a pin and a match complete the list of essential extras, although a Kodak Flash Sheet Holder is a great convenience. With flash sheets, no lamp is necessary, there is a minimum of smoke, and they are far safer than any other self burning flash medium, besides giving a softer light that is less trying to the eyes. Many interiors can be taken with the flash sheets that are impracticable by daylight, either by reason of a lack of illumination or because there are windows in a direct line of view which cannot be darkened sufficiently to prevent the blurring of the picture.

Evening parties, groups around a dinner or card table or single portraits may be readily made by the use of our flash sheets, thus enabling the amateur lo obtain souvenirs of many occasions which, but for the flashlight, would be quite beyond the range of the art Preparation for the Flash – The camera should be prepared for time exposures as directed on page 11 of this manual except that the No.

Strong, founded the Eastman Dry Plate Company in In celluloid roll film was introduced, and in , the company name was changed to its final form, the Eastman Kodak Company. The first cameras were simple wooden boxes, with the shutter cocked by a No. Eastman was greatly aided in his camera development by Frank Brownell, a cabinet maker who turned to the manufacture of cameras in the early s.

Brownell designed most of the early Kodak cameras, and was responsible for the design of the famous Brownie cameras, which for the first time brought snapshot photography within reach of the masses.

After printing hundreds of photos of landscapes and portraits and comparing them under high magnification, we think the Epson Expression is the overall best photo printer available right now. It outperformed more expensive large-format printers in our quality tests, .

Trainers Pubpages has been retired Starting in at least , and maybe earlier, the University of New Hampshire has had a service to allow students, faculty, and staff to have a personal home page. Pubpages was the home of many a student homework assignment along with personal sites from faculty and staff about their research work, teaching, and personal interests.

At the end of December , all Pubpages addresses were permanently redirected to this webpage to help any remaining visitors following old links to pubpages. UNH now has a new service for faculty, staff, and students to make personal webistes using a modern content management system. That system is known as myPages and is avaialble at mypages. Many faculty and staff who had old Pubpages sites now have new ones in myPages. There is not any definitive list, though, to map from the old site names to the new ones.

Still, if you wound up here looking for something specific, you might still be able to find it by checking the sites within myPages.

He says that he found the sign"in the loft of one of my father’s chemist shops. I was probably no more than 14 years old when I came across it clearing out that roof space which had been untouched for decades.

The baddeleyite U—Pb ages of multiple drill core samples of troctolite and gabbro indicate that all of the mafic rocks studied from different components of the Voisey’s Bay intrusion: On the basis of combined geological and geochronological evidence, it is suggested that the Voisey’s Bay Ni—Cu—Co deposit was formed during the same period.

The zircons coexisting with the ca. The zircons from normal troctolite and some of the olivine gabbro samples are coeval with the baddeleyite, while zircon from the varied textured troctolite and feeder olivine gabbro are much younger at The identical ages of the younger zircon population and the Voisey’s Bay syenite that cuts the mafic rocks indicate a link between zircon growth in the mafic rocks and contact metamorphism, related to the emplacement of the syenite.

Various mechanisms of zircon growth were probably involved, including reaction of the Ma baddeleyite with a silica-enriched fluid with formation of a secondary polycrystalline zircon, and zircon crystallization from syenite micro-veins in the mafic rocks.

I am scanning over 1,"Kodachrome Transparency” color positive slides that my late father shot years ago. Luckily he hand-numbered the slides in order shot, however, at the top of most of the slides in the white paper border there are date stamps, either in ink or actual impressions in the slides, e. What are these dates? Or are they slide expiration dates?

I am trying to determine if I should append the date to the slide number after each scan. Probably a stupid question for the old salts, but here goes.

With the invention of the dry plate process and roll film, amateurs started taking pictures in great numbers. So many companies started up to supply them that they depressed the entire market. To survive in this highly competitive climate Eastman developed a complete and easy to use camera system he named Kodak, -You press the button, we do the rest. This marketing strategy not only allowed him to survive but also propelled him to the top of his field.

While the first known real photo postcard made its appearance in , they did not begin to be made in number until Eastman bought the rights to Velox photo paper with a pre printed postcard back, and began to seriously market it in A year later he put an inexpensive folding camera on the market that produced negatives the same size as postcards allowing for simple sharp contact printing.


The Brownie was a box camera first introduced in as a very simple leather-covered cardboard camera with a meniscus lens and no viewfinder, and can thus be considered as the first point-and-shoot camera. Kodak sold millions of them, making money from the film they sold, not the actual cameras. Not dissimilar to the strategy employed these days by inkjet printer manufacturers!

A wide range of models were produced, using several different film formats. The No 2 Brownie used rollfilm, which is still produced to this day, so this is the best model to go for if you want to try out this camera yourself. It was first introduced in and went through several incarnations until the start of WWII.

Inkjet prints[ edit ] For inkjet prints, pigment -based inks last generally longest when used with specific paper types, whereas dye -based inks can be optimal on more types of paper. Ink-jet paper types include swellable paper, porous paper, and cotton rag paper. Older chromogenic papers undergo more rapid fading compared to modern materials. For example, Fujifilm ‘s Crystal Archive papers have a quoted longevity of sixty years dark storage.

Very significant advances in stability were made in case of Kodak prints in , , and in the early s. These changes can often be used for the dating of color prints, and can be correlated with manufacturing changes documented in the technical literature. Some black-and-white prints are produced using ink-jet printers, or colour photographic paper using the RA 4 process.

Gelatin silver prints[ edit ] To achi[ edit ]ng lifespan, gelatin silver prints must be thoroughly fixed and washed. Besides rendering the image insensitive to further light exposure, fixer converts undeveloped silver salts in the emulsion into products that can easily be washed away.

Early history[ edit ] Adverti[ edit ]or Ansco Speedex Film, The company was founded in pre-dating Kodak in the photography business as E. That year the company headquarters relocated to Binghamton, New York. This was already a site of one of Ansco’s photographic paper manufacturing facilities. Just after that, in it settled a landmark patent infringement case against Eastman Kodak, which had been violating the Goodwin flexible film patent Hannibal Goodwin of Newark, New Jersey held by Ansco.

The settlement received from Eastman Kodak was very small compared to the damage done to Ansco, which already had financial problems as a result of business lost to Eastman Kodak. April During the period before the U. The Agfa-Ansco interests in the U. To assist the war effort, the company experts used available information to develop a similar product, first called Ansco Color, later Anscochrome.

After the war, Anscochrome was widely distributed, but met with limited commercial success in competition with Kodak products.
