Academic literature on the topic 'Early colour photographic processes'

The Himalaya is the greatest mountain range on Earth: the highest, longest, youngest, the most tectonically active, and the most spectacular of all. Unimaginable geological forces created these spectacular peaks. Indeed, the crash of the Indian plate into Asia is the biggest known collision in geological history, giving birth to the Himalaya and Karakoram, one of the most remote and savage places on Earth. In this beautifully illustrated book, featuring spectacular color photographs throughout, one of the most experienced field geologists of our time presents a rich account of the geological f

This chapter discusses one of few women documentary filmmakers of the Arctic, Danish Jette Bang. A prolific photographer and filmmaker in Greenland throughout her career, Jørgensen shows how the early color film Inuit (1940) was nimbly shot and cinematographically deliberate. Made for the 1940 International Polar Year, the film and accompanying photo book created substantial media coverage when it premiered in Copenhagen. Bang’s later films, including her depictions of a changing Greenlandic society in the 1950s and 60s, this chapter argues, were made with the intent to both document Greenlandic life in the post-war era and as a testament to Denmark’s benevolent colonial rule of Greenland. Bang’s films thereby showcase the welfare state and industrial modernization processes imported Greenland, while maintaining an interest in ‘traditional’ practices and customs.

As noted in the first edition of Geography in America, the term “remote sensing” was coined in the early 1960s by geographers to describe the process of obtaining data by use of both photographic and nonphotographic instruments (Gaile and Wilmot 1989: 46). Although this is still a working definition today, a more explicit and updated definition as it relates to geography can be phrased as: “remote sensing is the science, art, and technology of identifying, characterizing, measuring, and mapping of Earth surface, and near Earth surface phenomena from some position above using photographic or nonphotographic instruments.” Both patterns and processes may be the object of investigation using remote sensing data. The science dimension of geographic remote sensing is rooted in the fact that: (1) it is dealing with primary data, wherein the investigator must have an understanding of the environmental phenomena under scrutiny, and (2) the investigator must understand something of the physics of the energy involved in the sensing instrument and the atmospheric pathway through which the energy passes from the energy source, to the Earth object, to the sensor. The art dimension of geographic remote sensing has to do with the creative ways that the scientific interpretations are presented for visualization and measurement. The technological dimension of geographic remote sensing has to do with the constantly evolving hardware, software, and algorithmic manipulation and modeling involved in the collection, processing, and interpreting of data regarding the Earth phenomena under investigation. It is the rapidly advancing combination of these three dimensions over recent decades that has brought remote sensing to be a vibrant and dynamic part of the discipline of geography today. We wish not to dwell at length on the historical aspects of remote sensing as it relates to geography. This has been done quite adequately in the first edition of Geography in America as well as in other publications, such as the American Society of Photogrammetry and Remote Sensing (ASPRS) Manual of Remote Sensing series (e.g. Colwell 1983), that is now going through a third edition and complete update, and is being presented as a compendium of individual volumes that deal with specific aspects of remote sensing science.

As an alternative to radiography, a field-proven mechanized ultrasonic inspection system is discussed. Called Rotoscan, this system has been developed for inspection of girth welds during construction of long-distance pipelines, both on- and offshore. It is characterized by high inspection speed and instant recording of results. Unlike prevailing radiography, it provides immediate feedback to the welders. Recent technical improvements in flaw sizing and recording have allowed the application of rejection/acceptance criteria for weld defects based on fracture mechanics principles. The developme
