Lens Dreare: A Visual Mistake In Photography
Lens flare, a visual mistake in photographs caused by external light, is a very interesting example of atmospheric optics. While hated at first amongst photographers and cinematographers, lens flare is, nowadays, a must-have in photography and films. Starting with Citizen Kane in 1941, lens flare was first used intentionally in film. Lens flare is a result of particulate matter (matter that changes state within the atmosphere) interacting with light and, additionally, getting itself trapped inside a lens.
Atmospheric optics deals with how the unique optical properties of the Earth's atmosphere cause a wide range of spectacular optical phenomena. The blue color of the sky is a direct result of Rayleigh scattering which redirects higher frequency

    In the article Distorted Images: Western Cultures are Exporting Their Dangerous Obsession with Thinness, author Susan McClelland addresses the negative effect that western culture, especially western media, has had upon women in other parts of the world and how it relates to body image, thinness, racial features and even skin color. She interviewed several women who felt pressure to change their appearance to fit into the portrayed standards of Americanized beauty; white and thin. Experts say “cultures that used to regard bulk as a sign of wealth and success are now succumbing to a narrow western standard of beauty” (pg. 431) There is an increase of eating disorders in areas that have never had that problem until recently.…

    Often in life and in literature, people find themselves in overpowering situations. This is what Herodotus was referring to when he wrote, “Men are at the mercy of events and cannot control them.” In other words, people suffer not because of their own actions, but because of the situation in which they find themselves. This is true in considering Of Mice and Men by John Steinbeck because George and Lennie, the two protagonists, and other minor characters suffer due to events beyond their control. Herodotus’ quotation is also true in considering William Shakespeare’s Romeo and Juliet, because the protagonists, Romeo and Juliet, are also overpowered by the forces that surround them. Herodotus’ quote proves particularly true in considering the setting of both novels, the conflicts within the two texts, and the characterization of the protagonists and even the minor characters within the novels.…

    Martin Luther King, JR once said “The ultimate measure of a man is not where he stands in the moments of comfort and convenience, but where he stands at times of challenge and controversy.” This quote means that we only see people’s true color when they are faced with trouble or problems. I agree with this quote because you never know the people’s feelings until you know the problem they are faced with or are facing. Monster by Walter Dean Myers and Speak by Laurie Halse Anderson used theme and setting to prove the critical lens. The main characters in both these novels overcome challenging situations by taking advantage of the opportunities presented to them. In their struggle to make the best of their circumstances, the main character Melinda in Speak and Steve in Monster illustrate the critical lens.…

    Entrepreneurship, Jeff Cornwall at Belmont University defined it as, “A process of identifying, evaluating, seizing an opportunity and bringing together the resources necessary for success.” (www.belmont.edu) There are a wide variety of risks when it comes to starting and running your own business, just some of them are: under capitalization, poor management, market misjudgment, and lack of planning. Two of these go hand – in – hand, lack of planning and under capitalization, and this due to improper planning. For example, when someone says “Just looking!” while searching for an item in a new store, you put yourself in a bad situation because your business is not completely laid out. How can you budget money? If you do get your business up and going should you hire employees…

    Essay On Photorealism

    • 2084 Words
    • 9 Pages

    Photorealism originated in the United States in the mid-1960s in the wake of the Vietnam War. It is an international art movement involving the precise reproduction of a photograph in paint or the replicating of real objects in sculpture. The name Photorealism (also known as Hyperrealism or Superrealism) was coined in reference to those artists whose work depended heavily on photographs, which they often projected onto canvas allowing images to be replicated with precision and accuracy. Photorealism complicates the concept of realism by successfully mixing together that which is real with that which is unreal to a degree not previously achieved prior to it. The exactness was often facilitated further by the use of an airbrush, which was originally designed to retouch photographs. Being entirely representational, photorealism art is a natural counter to contemporary abstraction. Therefore, their canvases remain distanced from reality, both literally and figuratively.…

    In order to answer the title of this essay question I will be undertaking research into the main theme of distortion within photography. On top of this I will be incorporating the background information and series of work from two photographers who also base their work around the theme of diction however they achieve this by using two very different methods. Distortion is the alteration of the original shape (or other characteristics) of something such as an object, image, sound or waveform. Distortion is usually unwanted and seen as a photographic mistake and therefore people strive to eliminate distortion or minimize it. However in photography, distortion, as long as it works effectively, is welcomed more than eliminated. There are two main types of distortion when it comes to photography; these are known as optical distortion and perspective distortion. Optical distortion occurs as a result of optical design, when special lens elements are used to reduce spherical and other aberrations. In short, to create a distortion commonly described as optical this is a…

    Phenomena of Light

    Why is the colour of the clear sky blue ? The fine particles in the atmosphere have size smaller than the wave length of visible light. They can scatter blue light which has a shorter wave length than red light which has a longer wave length. When sunlight passes through the atmosphere, the fine particles in the atmosphere scatter the blue colour more strongly than the red and so the sky appears blue. If the earth had no atmosphere there would not be any scattering of light and the sky would appear dark. The sky appears dark at very high altitudes.…
