An underwater photomosaic technique using Adobe Photoshop™

A simple technique for taking systematic runs of vertical underwater photographs is described. Computer-based procedures for rectifying, matching, and assembling the photographs into mosaics using Adobe Photoshop™ software are then explained.     

From policy to platform: the digitization of Danish Cultural Heritage

This article scrutinizes the dominant discursive formations within digitization of cultural heritage in Danish cultural policy, with the ‘Danish Cultural Heritage’ portal serving as a case. The paper analyzes how the portal frames users’ participation potentials and how this relates to the objectives of the portal and official Danish digitization strategies issued in the period of 2007–2015. Furthermore, the article incorporates interviews with experts working with the portal and the digitization strategies in order to gain a closer understanding of the transformation from policy to reality. Even though discourses on participation and user engagement are detected within official cultural policy documents, the dominant discourses are those of administrative and managerial effectiveness and cooperation as well as increased production, innovation, and competition. A similar pattern emerges on the portal, where focus is on digitization and preservation rather than access and use. The interactions between technology, user/usage, and content are thus tailored on premises of ‘read only’ and ‘sit back and be told’ cultures rather than on the user-engaging ‘read write’ and ‘making and doing’ cultures.     

The Deleterious Dominance of The Times in Nineteenth-Century Scholarship

The Times was a mid-nineteenth-century newspaper phenomenon, defeating rival London newspapers through its skilful management, advanced technology, greater editorial resources and access to powerful politicians. Its authority enabled it to make and break governments. However, the uniqueness of The Times limits its usefulness as a historical source. This article begins with a brief history of The Times, before analysing how the newspaper remains centre stage in the historiography of journalism and of nineteenth-century culture more broadly, despite the digitization of provincial and other London papers. Over-dependence on The Times, it argues, has exaggerated the significance of London daily newspapers and underplayed the importance of weekly papers, particularly those published outside London. The Times was unusual because it was a metropolitan rather than provincial paper, with a focus on political news and a dearth of lighter, broader content, or news of events around the UK. Using quantitative analysis of recent scholarship, the article demonstrates that unwarranted conclusions are still drawn from over-use of this source and from a wider view that it was representative of nineteenth-century newspapers in general. The conclusion urges a more geographically and culturally nuanced approach to Victorian newspapers, beyond a metropolitan-focused political and cultural history.     

基于机器学习和图像形态学的彩色近代地图数字化——以近代上海地区地表水体信息提取为例

利用科学测绘技术绘制的近代地图作为一类珍贵的历史地理资料,不同程度上反映着过去的地表覆盖情况,数字化则是复原地图所载地表覆盖信息的重要途径。以《华东·上海》地图为例,实现并验证一种基于机器学习和图像形态学的彩色近代地图数字化方法。结果表明,该方法能够充分挖掘地图中的颜色信息和形态结构信息,以半自动方式快速准确地将彩色近代地图中的地表水体信息提取出来。该方法对数字化一类彩色近代地图具有参考价值,有望为精准复原近代以来地表覆盖变迁,深入理解人地关系变化提供数据和方法基础。

Cultivating digital mediation: The implementation of publicly funded digital museum initiatives in Denmark

ABSTRACT

The aim of this article is to review and re?ect on the factors defining the expected benefits that have influenced the implementation of digital mediation initiatives in publicly funded museums over the course of the last 20 years. The expectations directed towards digital museum mediation are established by taking a closer look at Danish cultural policy implementation and socio-technological development. Examples from a review of cultural policy documents, funding applications and reports, supplemented by articles from a museum practice journal illustrate trends and developments in digital museum mediation. This article identifies a development of digital museum mediation in three phases, from providing access to digitized cultural heritage to more user-oriented communication strategies such as personalization and participation. The analysis shows that, in a cultural political context, the adoption of digital mediation in institutions is part of a higher strategy where technological development acts as a catalyst for innovation in the cultural sector.
