Remote sensing - Essay Example 239) have defined the remote sensing as a field of science or art that makes use of energy reflected from the Earth that is later processed, evaluated and applied in order to assist one in retrieving information regarding the surface of Earth without physically having to be on it. Sun is the fundamental source of energy for all the creatures on earth. Sun rays falling on earth are partly reflected which are captured by the satellites for generating information. The first condition without which, the process of remote sensing can not take place, is the provision of electromagnetic energy as waves to a specific place or to a study area. Although there are many electromagnetic energy sources, yet the sun is fundamentally the best source of energy. Basically, the energy travels from a source to a target through a medium or vacuum. When it comes to the earth, the energy interacts with the atmosphere, and this interaction gets repeated when the energy is reflected from the study area to the sensor. After the electromagnetic waves have passed the atmosphere from some source, they interact with the study area. This interaction depends on the characteristics of the study area and also on the electromagnetic radiation sent to it. After the electromagnetic waves interact with the study area, part of them is absorbed and the rest is reflected back to the space. Recording and collecting the reflected electromagnetic waves requires a special type of sensor which is familiar with the reflective waves. The last step of this operation is to understand, disclose and apply the information that has been retrieved from the study area. The problem can be solved by conducting its comparison with the real information. In 1864, the British physicist Clark Maxell predicted the existence of electromagnetic waves and supposed that the magnetic and electric fields work together to produce radiant energy. In addition to that, he described the visible light to be composed of

Analysis and Meaning of Dante Gabriel Rossettis The Bocca Baciata Essay

Analysis and Meaning of Dante Gabriel Rossettis The Bocca Baciata - Essay Example Bocca Baciata can be said to the beginning of Rossetti’s shift in terms of style and medium in his paintings that later became the signature of his work. Bocca Baciata marked Rossetti’s beginning of painting singular female figures that evoke seduction and earthly pleasure. According to a fellow cofounder of the Pre-Raphaelite Brotherhood William The painting, just like Rossetti’s previous painting bore inscription that wrote; Bocca baciata non perde ventura, anzi rinnova come fa la luna. ‘The mouth that has been kissed does not lose its savour, indeed it renews itself just as the moon does2 II. Evolution of Dante Gabriel Rossetti as an Artist To fully understand, appreciate and decipher the meaning of Bocca Baciata on how it relate to Rossetti, it would be necessary to understand Rossetti as an artist to contextualize the meaning of the Bocca Baciata and fully understand the painting in the process. Rossetti as an artist did not employ a single theme in hi s works although the nature of his subjects primarily centred on women. His subject (the female) and how they were depicted evolved and it served as a mark on Rossetti’s growth and maturity as an artist and this has a significance in understanding Rossetti’s final paintings (Bocca Baciata was one of them) that became the signature of Rossetti’s work. ... hift of style is significant because Rossetti was not only one of the most accomplished artists during his time but also cofounded the Pre-Raphaelite Brotherhood which was a movement towards a particular painting style of stressing the importance of nature3. Bearing in mind Rossetti’s involvement with the Pre-Raphaelite movement is important because Rossetti’s later works that include the Bocca Baciata was still assessed under the standard of the artistic style of the brotherhood of whom he cofounded even when he attempted to depart from it. This resulted to the harsh criticism of his later works that led many critique of the Victorian painting to judge that the best of Rossetti’s works were those whom he had painted earlier. a. The first phase (from 1848 to 1853) The female has always been a central subject among Dante Gabriel Rossetti’s work. This was already evident from his very first public artwork which was The Girlhood of Mary Virgin. What differed from Rossetti’s later work such as the Bocca Baciata is not how the subject changed but rather, on how the rendering of the subject shifted. Bocca Baciata can be said to be similar with Rossetti’s first major work The Girlhood of Mary Virgin in many aspect although not necessarily on how the women were depicted. Bocca Baciata was Rossetti’s first work that marked his shift in terms of rendering the female while The Girlhood of Mary Virgin was Rossetti’s first work that made him prominent in having the female as subjects. Rossetti as an artist during the first evolution of his works can be likened to the growth of a boy to a man where the perspective about the female change as the boy grows to puberty and become a man. In The Girlhood of Mary Virgin, Rossetti’s boyish and impressionable nature was
