Dear Dangar Publishers,
The first photograph above is one of the many photographs taken by Jack Flange. Jack Flange is a famous photographer particularly specialises in photographing light and surfaces. The scientific value contained in his photograph above will be discussed and hopefully you will be convinced that the photographs taken by Jack is of high standard and the scientific ideas about reflection, transmission and refraction are well demonstrated.
In his photograph, the lower right hand side of the wood image shows the wood being reflected. Reflection happens when light bounces off an object (Science Hub, 2012). Particularly Jack’s photograph describes specular reflection, that is reflection off of smooth surfaces such as mirrors and in this case a calm body of water. Water is a reflective surface and when it is very still, the reflection of the landscape is perfect. However, if there are ripples or waves in the water, the reflection becomes distorted (Science Hub,

Particularly the photograph taken by Jack is of the form diffuse transmission. It is produced when light goes through a transparent or semi-transparent object with texture. Light, in this case, instead of going in one direction, is redirected to other directions, which are further discussed as refraction (Easycourseportal.com 2017). In jack’s photograph since the water is transparent, visible light is transmitted easily and the image of the wood in the water can be seen clearly. In the second photograph, the intensity of the transmitted light is smaller than the intensity of the incident light. This happens because of the transmittance of light in water. Transmittance describes the proportion of the intensity of the transmitted light to the intensity of the incident light (Gallik, 2011). In practice transmittance ranges from 0 to 1 (Gallik, 2011), therefore it results in a lower intensity of the transmitted light in the
New York City is known for its extensive collection of art museums ranging from the Metropolitan Museum of Art which is usually the most renowned to others such as the the Solomon R. Guggenheim or the Whitney Museum of American Art which are popular in their own rights. This abundance of art museums makes the city very attractive for foreign visitors. However, this abundance of choice can overwhelm even the most informed visitors who have a finite amount of time to explore what the city has to offer. Although all of the above mentioned museums have great collections of their own, the often unheralded Frick Collections might trump them all in terms of exceptional works which include some of the world's most celebrated Western artists, such as Goya, Manet, Monet, Rembrandt, and Renoir.
Jacob was an African-American artist, who eventually flourished in the art world during the Depression of 1920s, painting African-Americans life in Harlem, making social statements and thus, explaining their life during that time. Additionally, this made his art significant to spectators who praised his works. With no formal training in painting, it was easy for Jacob to ignore the rules that set him apart from other African-American painters and others, before him and in his time, such as Palmer C. Hayden, and Archibald Motely, Jr to whom he was compared. Jacob Lawrence artwork communicated historical data and his perspective of people he was familiar with in his culture. His work expressed how African- Americans struggled for health and social justice, how they were ignored by the Republican administrations, racial equality and eventually, why African-American voters would shift to the Democratic Party.

Tim Jenison, the man behind the documentary film entitled Tim’s Vermeer set out to replicate a painting in the style of the beloved artist Johannes Vermeer. In order to do this, Jenison replicated a system of lenses that he believed Vermeer had used hundreds of years before him for the sake of duplicating the correct light variations around the objects of his muse. The course of the documentary showcases Jenison as he first constructs this hypothesis of Vermeer mastering light, moves on to Jenison's development of his lense device, and finally to Jenison using his device to paint a work of art in hope that it will be comparably close enough to the work of Vermeer that his hypothesis can be proven. Whether or not Jenison succeeded can be debated and was one of the topics that the panel of professors including Professors Baugh, Gorchoff, Myers, Willhardt, and Wright discussed at the convocation.
There is, however, a slight opposition to this intense realism. It can be seen in Wood’s representation of foliage. The trees that appear in the upper left corner look like large green lollipops peeking over the roof of the house. The viewer knows that trees do not naturally look like that. Wood has depicted them as stylized and modern, similar to the trees seen is Seurat’s Sunday Afternoon on the island of La Grand Jatte. After viewing other works by Wood, it is clear that he has adopted this representation for the trees in many of his paintings.
It is where people can enjoy the water splashing on the shore while they stand on the warm sand. Looking out upon the ocean helps create a sense of wonder because it appears to go on forever and blends into the natural sky. While soothing sensation occurs as the waves approach and splash on the beach. Through the use a focal point, which appears to be the small children in the red shirts, the artist evokes feelings from many viewers who have visited the beach before. This brings back fond memories for those who have spent countless hours as children swimming in the ocean and enjoying the beach. It also brings back times of being relaxed by the soothing sounds of the ocean waves as the come onto the beach. The artist uses the element of color to help bring out more positive emotion. The white tips of the ocean waves help make the painting appear more realistic, the red shirt brings out the warmth and enjoyment of being on the beach, and the blue background brings out the cool soothing emotions with the natural beauty of the water and sky. These color help connect the audience into being reminded of all the fun going to the beach
Prior to the invention of the daguerreotype, the Camera Obscura was the main optical instrument that was used to project images onto paper. The Camera Obscura was a device in the shape of a box that allowed light, which was being reflected from the images that the user was intending to capture, to enter through an opening at one end of the box to form an image on a surface and an artist would then trace the image to form the most accurate impression of an image at that peri...

Books are still an ideal Christmas gift, so here are two suggestions for photographers that want to read about more that the technical aspects of photography, from authors Guy Tal and Bruce Barnbaum.
This painting is apart if a series of paintings by Jacob Lawrence which are separated in between two museums, The Museum of Modern Art and the Phillips Collection. The painting documents one of the most historical events in American history, the migration of African Americans from the agricultural south into the industrial north. Painting show a variety of geometric shapes and flat areas of color. The scene above showcase one of the biggest race riots in St.Louis. With the African American community being to crowded the urge to expand caused rioting up North.Lawerence brought a visual vocabulary that is well versed in
Twain's detailed images of the "gold," (1) "tinted... opal," (1) and "silver" (1) river, paint the beauty he finds in the surroundings. The "graceful curves, reflected images, woody heights, soft distances; and... marvels of coloring" (1) depict the opinion Twain has of the river. This beauty has been learned and appreciated through the years of living along the river and is revealed through his images.
Shadowgraphy - an optical measurement technique is a field measurement method (image forming method) based on variation of refractive index in the flow field. The density of a fluid varies with temperature, salinity, and pressure. And, the index of refraction changes with fluid density. If a screen is placed opposite the light source, these effects create shadows on the screen creating an image called a Shadowgraph. The image ca...
In optics, if a beam of light hits a boundary at a certain critical angle, all the light will be reflected back. In classical physics none of the light crosses the boundary, but is instead reflected back perfectly. If the light is viewed as a potential wave, however, the probability of the particle's location decays inside the second material. This means there is a chance the photon exists within the restricted area, but it does not propagate there. The distance that the decaying, or evanescent, wave travels into the second medium is determined by the change in refractive index at the boundary. The evanescent wave will be changed if it interacts with a particle after crossing the boundary. This change in the wave can be observed by a change in the amount of light reflected back on the side of the first material.
The Chinese and Greek are the first recorded people to figure out that when light shines through a small hole it creates an image on the opposite side of the incoming light. In about 330 BC the next person to study these optic laws was Aristotle, a great and respected philosopher, when he noticed that when light shined through a square hole it made a circular image. Aristotle studied the optic laws and figured out that if there was a box with
