Self-Portrait Essay In my freestyle English class I was assgined to create a personal essay about myself. This essay was to help me discover my true identity, who I really am not just to my friends and famlity, but to myself as well.

Etymology[ edit ] The coining of the word "photography" is usually attributed to Sir John Herschel in Camera obscura Principle of a box camera obscura with mirror A natural phenomenon, known as camera obscura or pinhole image, can project a reversed image through a small opening onto an opposite surface.

This principle may have been known and used in prehistoric times. The earliest known written record of the camera obscura is to be found in Chinese writings called Mozidated to the 4th century BCE.

Until the 16th century the camera obscura was mainly used to study optics and astronomy, especially to safely watch solar eclipses without damaging self portrait writing assignment format eyes. In the later half of the 16th century some technical improvements were developed: In Giambattista della Porta advised using the camera obscura as a drawing aid in his popular and influential books.

Della Porta's advice was widely adopted by artists and since the 17th century portable versions of the camera obscura were commonly used - first as a tent, later as boxes.

The box type camera obscura was the basis for the earliest photographic cameras when photography was developed in the early 19th century. History of the camera Before Turin Shroud and light sensitive materials[ edit ] The notion that light can affect various substances - for instance the suntanning of skin or fading of textile - must have been around since very early times.

Ideas of fixing the image seen in mirrors or other ways of creating images automatically may also have been in people's mind long before anything like photography was developed. The actual method that resulted in this image has not yet been conclusively identified. It first appeared in historical records in and radiocarbon dating tests indicate it was probably made between and Georg Fabricius —71 discovered silver chloridelater used to make photographic paper.

He also noted that paper wrapped around silver nitrate for a year had turned black.

After experiments with threads that had created lines on the bottled substance after he placed it in direct sunlight for a while, he applied stencils of words to the bottle. The stencils produced copies of the text in dark red, almost violet characters on the surface of the otherwise whitish contents.

The impressions persisted until they were erased by shaking the bottle or until overall exposure to light obliterated them. Schulze named the substance "Scotophorus", when he published his findings in He thought the discovery could be applied to detect whether metals or minerals contained any silver and hoped that further experimentation by others would lead to some other useful results.

The first effect of this cloth is similar to that of a mirror, but by means of its viscous nature the prepared canvas, as is not the case with the mirror, retains a facsimile of the image. The mirror represents images faithfully, but retains none; our canvas reflects them no less faithfully, but retains them all.

This impression of the image is instantaneous. The canvas is then removed and deposited in a dark place. An hour later the impression is dry, and you have a picture the more precious in that no art can imitate its truthfulness. The hour of drying in a dark place suggests he possibly thought about the light sensitivity of the material, but he attributes the effect to its viscous nature.

Scheele's forgotten chemical fixer [ edit ] Inthe chemist Carl Wilhelm Scheele was studying the more intrinsically light-sensitive silver chloride and determined that light darkened it by disintegrating it into microscopic dark particles of metallic silver.

Of greater potential usefulness, Scheele found that ammonia dissolved the silver chloride but not the dark particles. This discovery could have been used to stabilize or "fix" a camera image captured with silver chloride, but was not picked up by the earliest photography experimenters.

Fleeting detailed photograms ? He originally wanted to capture the images of a camera obscura, but found they were too faint to have an effect upon the silver nitrate solution that was advised to him as a light-sensitive substance.

Wedgwood did manage to copy painted glass plates and captured shadows on white leather as well as on paper moistened with a silver nitrate solution. Attempts to preserve the results with their "distinct tints of brown or black, sensibly differing in intensity" failed.

It is unclear when Wedgwood's experiments took place. He may have started before ; James Watt wrote a letter to Thomas Wedgwood's father Josiah Wedgwood to thank him "for your instructions as to the Silver Pictures, about which, when at home, I will make some experiments".

This letter now lost is believed to have been written inor Davy added that the method could be used for objects that are partly opaque and partly transparent to create accurate representations of for instance "the woody fibres of leaves and the wings of insects".Assignment Writing Service; Coursework Writing Service; Essay Outline/Plan Service Self-Portrait Essay.
