Transition of Art to Photography in Terms of Realism Essay

Transition of Art to Photography in Terms of Realism - Essay Example Presently, such a world seems unimaginable thanks to photography: it comes with visual souvenirs; pictures of common and prominent people; advertising pictures that create a desire within the public while, at the same time educating them concerning all products the modern consumer culture is capable of offering; medical, diagnostic devices; incredible perceptions of exotic places, together with the outer space; world news pictures; and most significant, pictures of the events, as well as intimate moments of personal life (Keil 19). The photography technology is partly chemical and partly optical, dating back in 1839. Shortly after its instantaneous discovery by William Henry Fox Talbot of England, together with Louis Jacques Mande Daguerre of France, photography get used in documenting foreign places of interest like India, the American West and the Holy Land. Apart from that, it got applied in portraits along with photographs of kings, statesman, as well as theater or even literary personalities. However, during the 19th century, cameras were in most cases in the hands of either professionals or entrepreneurs who were self-educated thereby trying photography as a trade. Photography does not require professional licensing or even guild membership; therefore, in the mainstream, anyone has the capability of buying the equipment, obtaining the directions, and proceeding. This directness of the medium makes photographic practice liberated from the traditions, which had grown up throughout painting or a variety of printmaking arts (Keil 32). With the introduction of precoated dry plates in 1878, the tiresome and cluttered coating of glass plates inside the darkroom or even dark tent, for those photographers out in the field got eliminated, and with the availability of precoated photographic papers, printing of photographs turned out to be much easier, while, at the same time, more predictable. As a result, photography could be exercised by hobbyists or amateurs, mor e so by lovers of the medium since the majority of the people, who had the leisure for an advanced hobby such as this one, were not only educated, but also sophisticated, and desired to come up with photographs resembling Art (Keil 47). In the past, film cameras filters got used in the modification of both the spectral content i.e. color, intensity of light, while, at the same time, generating outcomes like soft focus. However, digital cameras tend to operate differently when it comes to color; there is a possibility of performing color modification in camera with ease by setting white balance. Therefore, for film warming, as well as cooling filters, or those filters capable of converting fluorescent light unto daylight where necessary, digital has the ability of achieving the same effects through internal operation of the digital data. There as a number of filters needed for digital including a polarizing filter, special effect filter, a UV filter, filters for infrared effects, a n eutral density filter plus a given graduated neutral density filter. It is impossible to digitally simulate the results of a

Enviromental issues (carbon footprints) Essay Example | Topics and Well Written Essays - 2250 words

Enviromental issues (carbon footprints) - Essay Example According to the American Meteorological Society (AMS, 2007), the direct human impact on the climate change is through the enhanced concentration of trace gases such as carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor which, collectively, are known as the greenhouse gases. With the enhanced amounts of greenhouse gases in the earth’s atmosphere, the infrared radiation emitted by the earth and its atmosphere is blocked by the thickening blanket of greenhouse gases, resulting to increased warmth in the earth’s temperature in its attempt to equalize the incoming and outgoing flows of energy. AMS (2007) further reports that Carbon dioxide (CO₂) accounts for about half of the human-induced greenhouse gas contribution to global warming since the latter part of 1800s. CO₂ concentration has been increasing mainly from fossil fuel burning and partly from clearing of vegetation. Significant part (50%) of the increased CO₂ emissions remains in the atmosphere, while the rest of the earth absorbs continually the remaining 50%. Interestingly alarming is that the atmospheric CO₂ concentration has been increasing at a much faster rate than any other observed in the past several thousand years’ geological record. The World Wildlife Fund (WWF, 2009) reports that around 97 percent of the CO₂ emitted by the western industrialized nations is mainly coming from burning coal, oil and gas energy. The western industrialized nations spew into the atmosphere approximately 25 billion metric tons of CO₂ each year, which is enough to cause temperature build-up that seriously disrupts the world climate’s natural balance. As the scientific community continues to understand, monitor and discover things about the environmental changes happening around the globe, it also tries to translate scientific discoveries into
