Historical Photographic Processes Essay Example for Free

Historical Photographic Processes Essay The Cyanotype, also known as the blue print process, was invented by Sir John Herschel in 1842 and made popular in the field of photography by Anna Atkins, a British botanist and photographer, who did a series of leaf prints and published a series of limited edition books of cyanotype prints (Rosenthal). The earliest examples of cyanotype photographs, therefore, consist of prints of leaf species. Cyanotypes are named for its blue-green (cyan) hue. It uses light sensitive Ammonium iron (III) citrate and potassium ferricyanide to reproduce an image. The Division of Rare and Manuscript Collection of Cornell University explains the process in its website: A piece of paper is first sensitized with a solution of ferric ammonium citrate (an iron salt) and potassium ferricyanide (a crystalline iron salt) and dried. The prepared paper is then contact, or placed in direct contact with the negative, and exposed to sunlight until an image begins to appear on the paper (usually about fifteen minutes). As contact prints, they are always the same size as their negatives. In the final step, the print is washed in water to oxidize the iron salts and draw out the cyanotype’s brilliant blue color (A. D. White Project). Since the 1980s up to the present, the blue print process is still used by some architects and engineers because of its simple process and low cost. The Albumen Print Process The albumen print process was invented by in 1850 by Louis Desire Blanquart-Evrard and became the popular photographic printing process for the next half decade A. D. White Project). It uses the albumen in egg whites to bind photographic chemicals to paper. The process begins by mixing the albumen with iodide of potassium and water. After the mixtures has been allowed to set for some time it is poured over a glass plate (or later on, on paper) which, in turn, is immersed in a bath of nitrate of silver and glacial acetic acid to sensitize it and make it ready for exposure in the camera. The plate is removed from the camera and poured with a saturated solution of gallic acid, followed by a solution of hyposulphite of soda, and then washed over a stream of water. When dry, the picture is ready for printing (Ross). Albumen prints are prone to fading. The general tone is yellowish with cream-colored highlights and deep chocolate brown shadows (A. D. White Project). Cited Works A. D. White Project. Division of Rare and Manuscript Collection, Cornell University. 14 April 2005. http://cidc. library. cornell. edu/adw/cyanotype. htm.

The Authenticity of Hecate in Macbeth Essay -- Macbeth essays

The Authenticity of Hecate in Macbeth      Ã‚  Ã‚   The authenticity issue of Macbeth's Hecate endures. Recent critics still argue about whether the scenes are Shakespearean, why they are or are not, and what the implications are one way or the other. Some critics cling to the authenticity of the Folio while others wave their copies of Middleton's "The Witch" in protest. The modern director and reader then will find no clear direction to read or not to read from textual scholarship. Instead, would-be travellers to the world of Macbeth had better consider their options and ask specifically: what does Hecate add with her appearance and how do these additions impact the play?    Some critics have made the mistake of trying to dismiss Hecate as a fetching song-and-dance girl. In his Introduction to Macbeth, editor Kenneth Muir remarks: "The Hecate passages were clearly invented to introduce the songs and Middleton is usually blamed for these insertions" (xxxiii). But more recent critics like Henri Suhamy take umbrage with both the form and the substance of this argument. Suhamy notes: "the direction printed in italics in the Folio, after line 33 (III,v)--"Musicke, and a Song"--does not mention any identifiable song, contrary to what is indicated by most editors" (274). Stallybrass seems also to believe that Hecate is there to dance, but at least he credits her with a particularly important number: "the dance of Hecate and the six Witches gives a concrete dramatization of the 'deed without a name' (IV.i.49) which reverses the whole order of 'Nature'" (200). What Hecate's interpolation really supplies, however, is order and much more: balance, authority, direct ion, and reason are all part of the substance she provides.    .. ...ologie."

Waze-Analytical Proposition

Strategic Value of Information Technology – CRM / Analytics Waze- Analytics Proposition 1. waze currently gathers the following data on its clients: GPS data – where users are and when, the application learns the users driving routes in order to give them the best personalized route to their destination. 2. We propose to add new data regarding user’s personal characteristics and consumer preferences. Once the system detects that the user has stopped in a spot of interest – shopping center, gas station etc. a short questionnaire will pop up.This will include 2-4 questions regarding user characteristics and preferences relevant to specific place. In return to answering the questions user will receive points – user who gains a certain number of points will receive an e-coupon as an incentive to cooperate. For example – User stops at a specific shopping center and following questionnaire pops up: 1. Gender: Female / Male 2. Age group: 18-22 / 23- 30 / 30-40 / 40-50 / over 50 3. What stores do you plan to shop at? A list of participating stores in the shopping center 4. A specific question regarding one of the stores chosen by user in Q3.The final lists of questions will, of course, be devised by our marketing specialists. 3. Together with current user data regarding – time and place the additional demographic data and consumer preferences collected provide businesses with a unique set of valuable marketing information. Waze can collect the information and sell it to different businesses which will analyze it for their specific need. An example of how this data can be useful: â€Å"Paz† and their â€Å"Yellow† convenience stores might decide to purchase consumer data from waze.Then they might find out that at a certain location between 2 to 4 PM a large amount of mothers of young children consistently stops at the competing â€Å"Delek† gas station across the street. Then â€Å"Paz† will dec ide to advertise via waze a diapers sale at â€Å"Yellow† at this location during these hours, thus attracting the mothers to fill their tanks at â€Å"Paz† and shop at â€Å"Yellow†. This way waze wins twice – first it gets paid for the data that they collect and then they get paid again for the focused advertising through their application.

Cubism and Multiplicity of Narration in the Waste Land

Cubism and Multiplicity of Narration in The Waste Land Abstract The aim of this essay is to consider the multiplicity of narration in The Waste Land and its relationship in enrichment of content and meaning in the poem. There is an attempt to convey the Cubist traits and find concrete examples in the poem. This study will try to specify evidences for conformity of cubism and multiplicity of narration in the poem. While Eliot juxtaposed so many perspectives in seemingly set of disjointed images, there is â€Å"painful task of unifying .., jarring and incompatible perspectivesâ€Å" in The Waste Land. Like a cubist painting, there is a kind of variety of narration in unity through the poem. The usage of different languages and narrations in the poem†¦show more content†¦Part of this sense of the totality of the modern self adding up to a fractured variety emerges, not just from the shifting sense of the images and the multiplicity of narration , but also from the variety in the verse style. Its as if in the modern age, there cannot be a single authoritative way of expressing how one feels. There is not enough confidence in the forms of language itself. Just as the traditional community has become the unreal city, a vision of a modern inferno. So The Waste Land is abundant with multiplicity of narration in different language and set of seemingly disordered images. The images in The Waste Land are supported by two distinct ways of narration. The lyric voice opening the poem uses metaphoric, often symbolic images and speaks in repetitive, stylized syntax. It has suggested on the one hand order and propriety, and on the other hand stasis. This voice speaks with authority and finality as it recurs in scenes throughout the poem where the vision of barrenness and revulsion from life is intensely clear and controlled. This voice contrasts with many voices speaking in metonymically rendered narrative scenes full of movement and change. These other voices resist categorization. These voices rang from vivid characters such as Marie, the hyacinth girl, Stetson’s friend, Madame Sosostris, the nervous woman, the pub woman, Tiresias, and the Thames daughters,
