Born in Vancouver in 1946 Wall began drawing and painting at an early age In the mid 1960s he studied art history at the University of British Columbia while continuing to make art inspired by the emerging Conceptual art movement and its anti capitalist creed to decouple art from aesthetic and market value This culminated in Landscape Manual 1969 70 a black and white booklet composed of snapshots and texts documenting a car ride Wall took through Vancouver s gritty suburbs Despite this breakthrough work Wall found himself dissatisfied with the Conceptual direction and from 1971 to 1977 he took a break from artmaking In the meantime he embarked on a doctorate in art history in London where he read voraciously philosophy critical theory and histories of painting sculpture and photography He also immersed himself in European art cinema particularly the narrative films of auteurs such as Robert Bresson Ingmar Bergman and Rainer Werner Fassbinder Upon returning to Vancouver in 1973 Wall set out to make a film with collaborators lan Wallace and Rodney Graham Though the project was never completed this foray into moving image storytelling inspired his cinematographic photograph a concept central to his later practice in which each photograph is carefully staged Word Length 650 700 Total Overview For this bundle your formal analysis must be a sort essay length response of 5 paragraphs in length Your will need to use exactly 3 elements to analyze the photograph in detail in order to make your argument about the photograph Use the Guide to Writing a Formal Analysis and the sample for additional support Keep in mind that the sample is structured differently from the specific format I outline below So make sure you follow the specification outlined below and not the sample Specifications for Constructing the Short Essay Paragraph 1 Introduction Your introduction should include Mid Term Exam ART 3648 History of Photography a Basic details The name of the photographer artist title provenance date and medium b Context A very brief description of the work including what you think the subject is c A road map This is like a movie trailer it gives the reader a preview of your essay d Thesis statement This is a one or two sentence statement where you make your argument s main claim Paragraphs 2 3 and 4 Separate Body Paragraphs Use three different formal elements one per paragraph to analyze the photograph Together these paragraphs constitute the reasons and evidence that supports your overall argument about the meaning the image Begin each paragraph with a topic sentence that addresses the significance of the element ye have chosen The topic sentence should make clear to your reader how the following analysis supports your overall thesis statement Address how and why the key elements used by the photographer artist create meaning Make sure you not only describe the work but use description to support your argume Thus you are using description for the ultimate purpose of interpreting and or evaluating the photogra In this process you should be moving between description and analysis unlike the one paragraph form analysis Bundle 2 where you do all your description first and then move to to the analysis
