The rules on this page originally comprised two main categories. Alcohol slide rule by J Long, London, made of boxwood and probably dating from the early twentieth century. The rule is almost certainly from a box containing a Sikes hydrometer, which it would have been used in conjunction with see Miscellaneous instruments pages. This appears to be primarily a gauging rule for determining the content of casks whether standing or lying and also functions as a comparative rule. Nine inches long, boxwood and brass.. The upper face is used for costing and the lower face for reducing. A two foot, two- fold rule. A boxwood and brass, three foot, four- fold rule, probably dating from the early twentieth century.

I’ve had pretty good luck using a Canon flat bed scanner, but how about the experience of others? Publish Preview kdanvers 7 years ago I use a Canon CanoScan f for all of my negative scanning and I like the results. I simply lay the lantern slide on the scanner bed and scan them as positives, doing my best to make sure they are as straight as can be. I also use Canon’s Toolbox and driver for the scanning.
Yes kids, you can make your own lantern and slides. It’s easy and fun. In the “Entertainment” video of the Introduction section you can see a real magic lantern being operated, and some real slides like the ones you can make by following these instructions.

After measuring the I-V curve from 0 to ma and ploting in Excel shows the first few points coming up from zero to be off the straight line you get afterwards, so eliminating them and plotting from to ma gives this straight line: Testing a PR4 lamp rated 2. When the voltage gets to 3. Although given for currents close to the rated current these relationships give a feel for how incandescent lamps work.
Important as camera obscuras are to the history of screen projection, the invention known as the magic lantern was associated far more closely with projection screens – because it is, in effect, a slide projector by another name, as well as ‘the forerunner of all film screens’ (Kittler 70).
Posted on Wednesday 5th April, by broadlandmemories Followers of Broadland Memories on Twitter and Facebook will have seen mention of the recent purchases for the archive of two sets of photographs of the Norfolk Broads from the late 19th century. These fascinating images document family holidays during the early years of the boat hire industry, providing a wonderful snapshot of boating during that era, and they include some incredibly rare photographs of pleasure wherries and the Broadland landscape.
The first collection were bought as a group of three lots of loose pages from an album which had been split apart by a dealer. Precise dating has been difficult, but researching the landscape scenes via contemporary guide books, census returns and trade directories, and the subtle changes in ladies fashions during the latter decades of the 19th century, led me to the conclusion that they are c The presence of a photograph of the Norwich Angling Club annual dinner menu also provided an initial starting point for that date.
The collection features a very well to do, probably extended family group aboard two pleasure wherries and a larger steam ship called Phoenix. I think they they were possibly taken during more than one trip. Sadly, there are no names, or real clues to where they came from. Other photos from the pages I bought include three or four which were taken on the Dutch and Belgian Canals, plus a couple of London scenes.
The first wherry is named as The Eagle — not a wherry name that I have come across before, nor can find mention of in the usual book sources, but it looks to be a quite rough and ready conversion from a trading wherry. The family group are pictured aboard The Eagle in the photograph above.

The slides were used in initiatory rites and for general instruction. A complete set of Masonic slides, including those relevant to Scottish Rite, York Rite and Eastern Star and all the related appendant bodies would number well over slides. This Magic Lantern dates to the late ‘s. These were the days before electricity and light bulbs. The base of the lantern was filled with kerosene and the wick was lit and adjusted similar to a hurricane lantern. The slides were slid onto the track one at a time projecting the image on a wall or screen.
Created as a set of 24 slides based on Sir John Tenniel’s original illustrations for the Lewis Carroll classic but altered to avoid copyright conflicts, these gems were meant for viewing on a magic lantern, or Laterna Magica — a primitive projector dating back to the 17th century, consisting of a concave mirror in front of a light source.

By the end of the 18th, it was being used to entertain audiences in the United States. During the second half of the 19th century it was a very popular form of mass entertainment, until motion pictures replaced it early in the 20th. Oxygen and hydrogen were burned on a limestone surface to produce limelight, which was projected through colored scenes hand-painted on glass slides, resulting in brilliant images that could be shown to up to hundreds of people at a time.
Stowe’s novel was apparently translated into this medium as early as September, A brass band was stationed on the balcony to attract the stranger. All that’s known is that it organized the story into 3 parts and 25 pictures. The various kinds of slides available below were all manufactured later in the century by the C.
They were designed in by Joseph Boggs Beale, America’s leading magic lantern artist.

History[ edit ] There probably existed quite a few other types of projectors than the examples described below, but evidence is scarce and reports are often unclear about their nature. Spectators not always provided the details needed to differentiate between for instance a shadow play and a lantern projection. Many did not understand the nature of what they had seen and few had ever seen other comparable media.
Projections were often presented or perceived as magic or even as religious experiences, with most projectionists unwilling to share their secrets. Joseph Needham sums up some possible projection examples from China in his book series Science and Civilization in China  Prehistory to CE[ edit ] Main article: Shadow play usually does not involve a projection device, but can be seen as a first step in the development of projectors.
The history of animation started long before the development of have probably attempted to depict motion as far back as the paleolithic period. Shadow play and the magic lantern offered popular shows with projected images on a screen, moving as the result of manipulation by hand and/or some minor mechanics.

I have a very untidy computer desktop. If I right-click on a jpeg, I can choose to open it with one of fifteen different applications, or I can share it on one of eight different online platforms. If I move from my desktop to the internet and right-click on an image, I can perform twelve different operations on it, one of which is saving it back to my desktop. We are all familiar with the latest statistics, with their proliferating number of zeroes at the end, telling us how many photographs are taken and shared every minute.
Much ink has been spilled, some even by me, on the implications of all of this for photography. Usually the talk is of rupture. There is only one Coliseum or Pantheon; but how many millions of potential negatives have they shed,—representatives of billions of pictures,—since they were erected!
