Introduction: Benzopinacol can be prepared from benzophenone in presence of sun light (photochemically) using isopropanol as the reducing agent in presence of acetic acid. Acetic acid is added to prevent the cleavage of benzopinacol to benzophenone and benzhydrol by the alkali derived from the glass container used for the reaction. Benzopinacol obtained in the first experiment is converted to benzopinacolone by heating under reflux (5 minutes) with glacial acetic acid containing trace amount of iodine

time, I taught the children in the classroom how the Polaroid camera works and explained to them the process of taking photographs with the camera. Using instant film is unique because unlike film photography, it does not need to be processed with chemicals or in a darkroom; the film develops right before your eyes. Using this kind of film allowed the children to watch each photograph develop. I explained to the children that over time photography has changed and the materials and formats we use have

Fundus Camera Reticle Setup (Mydriatic) An often overlooked and critical step in obtaining sharp images is to set your reticle. The reticle is the adjustable viewfinder crosshairs and is unique to each operator’s eye visual acuity. To adjust, place a white piece of paper in front of the camera (alternatively, you can use the camera lens cap on), raise the illumination light to highest and while looking through the viewfinder, turn the eyepiece clockwise and counter-clockwise until crosshairs are

A significant part of the movie was when Everett, Pete, and Delmar discovered a mysterious group of people dressed in white walking in one direction towards some unknown destination. The camera panned around the three as they take in the scene, staring in awe at the swarm of people around them (Cohen, 0:17:10). The main protagonists had no idea what was going on, and neither did the audience. The camera in this scene was probably shot mounted to a dolly, as the movement was smooth and clearly controlled

Soon after during the early 1930’s, the Technicolor Motion Picture Corporation released the first three-color Technicolor technology. This color process needed a unique type of camera that was able to split the image into three different sections of the film. Filters that were red, blue, and green were used to position the light to the matching filter, once the recording was done the different strips were then combined and developed into a solo color strip that was played through a projector. This

Technicolor Process Number Three was developed in 1928. The major change to Technicolor Process Number 3 is that it no longer included the projection print that was made out of cement. Instead it used a print created by dye imbibition. It still used the red and green filters from the previous phases. Through this phase, Technicolor continue to grow their corporation. “As evidence of the increased color mindedness throughout the industry, Technicolor had the contracts for the ten months beginning

In The Matrix, a science fiction film based in a post-apocalyptic world after a Terminator Scenario (Where machines attack humans) aligned event, the birth of a hero is shown. Nothing is what it seems in the Matrix, as it stands only as a device to distract people from realizing their cattle like existence, which is in essence an illustration of the ideology of Karl Marx, where reality and the way of life in the Matrix is maintained, oppressed, discovered, and eventually explained. There are various

Question 1 (50 Marks) • Subject Matter 1: Portraits of the Hill tribes Jason wants to spend some time taking half body portraits of the long neck ladies, I would recommand him to consider investing in a telephoto lens.

For portrait photography, in my opinion, prime lens with focal length between 70-135mm are

As we learned in class, the Motion Picture Patents Company was originally formed to resolve conflicts among the competing members of the motion picture industry. However, it ultimately lost its position as the dominating force controlling the industry only ten years later. As we read about in Scott Curtis’s essay, the reasons for the MPPC’s decline varies, but can be summarized by focusing on three major causes: the influence of litigation; competition from independent companies; and mistrust amongst

Tim Burton is an animator, screenwriter, director, and illustrator, best known for the dark, twisted, cinematic flair that his films contain, along with a smooth blend of horror and fantasy. Inspired by animator Walt Disney, and writers Roald Dahl and Edgar Allan Poe, it’s no surprise that many of Burton’s films focus on fairy tales. But, unlike many fairy tales, Burton’s fairy tales contain dark tones and moods that many fairy tales lack. Burton emphasizes these dark tones by manipulating lighting

Let’s go back in time. Let’s think how we get all these amazing pictures that hold so many memories to us. As they say a picture is worth a thousand words. Who invented photography?

BUSINESS STUDIES FILM RREVIEW: THE INFORMANT! NIVASHA BUDHRAM 12 One of the many baffling wonders of Steven Soderbergh’s lively dark comedy The Informant! is that it is always clear what the main character is thinking. This therefore presents a challenge to viewers to decode the main character and get an understanding of his thoughts and understand him as a person. For example, in high-stress situations, his mental processes are nervy, hilarious murmurs of daydreams about polar-bear hunting

George Eastman, J.P. Morgan, John Rockefeller, and Andrew Carnegie were all Captains of Industry. They were very successful and created innovations and inventions that had an influence on America. Many of their innovations are still used today and have been innovated more over time. George Eastman, the founder of Kodak, invented film to make photography easier.

In 1880 a young bank clerk, George Eastman, founded a company to manufacture photographic dry plates in Rochester, New York.

For the early days of film in the 1800’s a lot of interesting things happened. It was about developing the tools to capture your art. This art also went through, and still is, going through development. Reading up about the history and development of the Kinetoscope interested me. In 1891, Thomas Edison and William Kennedy Laurie Dickson made a single-viewer peep-show device in which film moved past light called Kinetoscope. National Federation of Women’s Club had the honor of the first public demonstration
