Letters to Lillian (Photogaphy)

People used photography to record special events or social gatherings. Photographs need need oral texture or explanation otherwise images become fractured and imperfect. In the early nineteenth century most pictures were taken in a studio with a studio photographer. Very few people owned a camera or developed their own photographs The most commen type of photograph was the wet collodion process. This entailed coating of glass plate with a mixture of collodion and potassium iodide, sensitizing the plate in a bath of light sensitive sliver nitrate particles; putting it in a dark room for coating and developing plates. The wet collion process was too involved and messy for anyone but professional photographers. In 1888 Kodak announced that they know have handheld that could hold enough film for 100 exposures. By the end of the 19th century more people were seeking instruction on photographic techniques and methods. Towards the end of the 19th century women were starting to get in to photography. 1902 appeared an article in the Halifax Daily Echo there is advice to pursue photography as a hobby. A tripod camera dose allow longer exposure if lighting conditions demands it. To operate a camera in the the early 20th century, a black cloth was drawn over the head, and the lens cap removed the image would appear upside down. There is a piece of glass located at the back of the camera that you can move to focus. when the photographer is satisfied with the scene the lens is recapped, the thumb screw tightened to hold the groud glass and plate containing the unexposed plate placed in the camera the slide in the holder was drawn back and the exposer time is counted off. When the plate is had been exposed to the photographers satisfaction the slide is placed in the holder. The exposed plate can be put in a carrying case for later development. Plates were developed inthe dark room, with the aid of a ruby lantern; a lantern with red glass whose light helps photographers see what they are doing. An article in the Halifax Daily Echo explain how a woman moon night scene uses a cutting out a tiny circle of a white piece of paper and plastering it to the the glass side of the negative to make it look like night time. You can also fabricate by placing a negative with a landscape scene against another negative and exposing both to a blast, the black and white the ground and trees will appear to have snow. To make prints from the plates, a printing frame was used to insert both paper and negatives. The printing frame was exposed to the sun for a period of time allowing the image to appear on the paper. Dry plate process with dark room development would soon disappear; devlopment of both negatives and prints became the direction of commercial use.

The first commercially successful photographic process were based on an proprty of chemical that turns from a light silvery gray to black when exposed to light. Some experiment reason that a sheet of paper or glass coated with silver nitrate and exposed to light show a shadow would develop in a image as ligt turn to black. Pictures can be reproduced indefinately by placing the negtive and image produced. Paper is based in the use of the negitive the image is produced in much less sharper image. Daguerreotype is a less popular method of photography and needs liensing to use. Next development was the glass plate negitive, which was also coated in silvser nitrateon the surface of a glass plate. the clear glass overcame the fuzzinness that sometimes appeared in the image, and made it easier to make coppies of of each picture using the negitive to make paper prints. the plate had to be used before it dried, this process is known as wet plate photography. The next major development was the dry plate negitive which made taking a picture cumbersome. This was replaced by coated papers which served as backing to hold the emulsions for negitves. No londer have to rely on photosensitive chateristics of silver nitrate. Carbon prints are hardened slightly when exposed to light. With glass plates; placing plate against ba sheet of paper and letting light pass throgh negitve, producing a  photo size negitive. Due to the to a tendency to curl film and they producded in 1903 non-curling variety was developed, and began to be highly used. 1913 film began to complete with the the glass plate negitive, which eventully supplanted. History of photography touch many mainstream important trends.

1940 the autographic freature was on most models, enables th photographer to write on the film with a metal stylus through the backing paper and special tissue. the feture was accessible via a flap on the bak of the camera. Speed graphic of 4×5 inch plate camera dominated photojournalismin America during the 1930’s. The speed graphic was introduced in 1912; was manufactured by Graflex, a New York based camera maker. The Single Lens Reflex designs comes from the 17th Century camera obscuras. Twin Lens Reflex design where the image is viewed through a second lens; to was to cumbersome for for plate cameras. In the 1930’s they started to appear in small role cameras. Franke and Heidecke intro duced the first Rolleiflex TLR in 1929. Cheaper Rolleicord was intro duced in 1933. In 1913, Oskar Barnack a German design enginer, introduced a prototype 35 mm camera. 1924 the camera went into production at the Leitz factory in Germary. In 1934 Kodak produced their first 35 mm camera The Retina 1.
