The Warnerke roll (paper) film holder in a camera<\/p><\/div>\n

Toronto<\/strong>. The idea of roll film revitalized the use of sensitized paper (negatives). In fact various roll film mechanisms were developed to use the medium in cameras. An example is the Warnerke Roll Film Holder.<\/p>\n

Editor Robert Lansdale wrote about this use of paper in his issue 27-1 article “Advance of the Paper negative \u2026and the roll film holder”.<\/p>\n

He begins his article, “The use of paper as a base for negative images has played an\u00a0important part throughout the history of photography. At photography\u2019s inception, Fox Talbot\u2019s Photographic Drawing <\/i>of 1834\u00a0captured the shadow image of plants and ferns within the body\u00a0of the paper, while his Calotype <\/i>of 1840 became the system to\u00a0produce multiple positive prints from the prime paper negative.<\/p>\n

“Criticism against fuzziness and lack of detail caused by the\u00a0inherent grain of the paper led to the idea of waxing the paper\u00a0before an open fire to induce translucence to the fibers. Le\u00a0<\/i>Gray\u2019s Waxed Paper <\/i>process of 1851 prepped the paper with\u00a0wax before sensitizing.<\/p>\n

“Glass as a base became desirable with its clarity and stability: albumen became the carrier to the sensitive silver salts. With\u00a0Scott Archer\u2019s discovery of collodion as the carrier in 1851, all\u00a0systems were quickly eclipsed by the Ambrotype <\/i>and Wet Plate\u00a0<\/i>Process. <\/i>The wet plate reigned supreme for some 20+ years due\u00a0to its fine grain and greater speed. Other improvements were\u00a0introduced in 1864 with the invention of collodion-emulsion <\/i>by\u00a0Sayce and Bolton, thus doing away with the necessity of the silver bath, while Dr. Maddox in 1871 substituted gelatin for collodion in emulsions, leading to the Dry Plate <\/i>era.<\/p>\n

“But devotees to the paper negative were still present. William J. Cox in the 1886 BJP Almanac expounded its virtues in ‘Paper Films Versus Glass Plates.’<\/p>\n

“He listed benefits as:
\nstorage of negatives \u2013 250 films equalled one inch of thickness of glass;
\nweight \u2013 two gross of paper negatives weighed less than one dozen glass;
\nfreedom from breakage \u2013 accidents could happen even while in printing frames;
\nfreedom from halation \u2013 it cannot occur, thus leaves and boughs against a bright sky are microscopically sharp;
\nincreased speed \u2013 nearly twice as fast;
\ncost \u2013 half the price of glass and even less on larger sizes;
\ncelerity of development \u2013 many paper negatives may be processed in a dish at the same time;
\neven coating \u2013 paper is pliable thus a more even coating can be obtained than on ordinary glass, and as paper can be applied to a curved surface, lenses of greater curvature of field may be employed; etc.”<\/p>\n
