Closing the Gap Between Photojournalist Research and Photojournalism Practice: Exploring the Motivations of the Subjects of Sensitive Photo Essays

This study is the first to inquire about the factors that influence people’s willingness to allow professional photojournalists to tell their stories through the medium of the photo essay. Guided by Self-Disclosure Theory, in-depth interviews were conducted with the subjects of 15 peer-judged award-winning photo essays. These were drawn from the multiple picture categories of the National Press Photographers Association (NPPA) Monthly Clip Contest, the annual NPPA Best of Photojournalism Contest, and the annual World Press Photo Contest between 2013 and 2017. The topics of the photo essays were sensitive in nature. Analysis reveals support and appreciation amongst photo-essay subjects for the profession of photojournalism. Motivations derived from the sensitivity and professionalism with which each interviewee was initially approached, a need to tell a different side of the story, a desire to inspire others or invoke change, and the memory-keeping and permanence afforded through published professional photojournalism.     

Semantic categorization of digital home photo using photographic region templates

In this paper, a semantic categorization method in generic home photos is proposed. In recent years, the semantic categorization of image has been a challenge due to the proliferation of digital home photos. Our approach is to detect semantically meaningful concepts contained in a photo. The proposed method incorporates an intermediate level of concepts, called local concept, so that it catches well semantic meaning of local regions of image as bridging the semantic gap of the low-level features and high-level category concepts. To detect the local concepts from the home photo, region segmentation by photographic region template and concept merging is also proposed. The efficacy of the proposed semantic categorization method was demonstrated with 3828 general home photos. The experiment results showed the proposed categorization method would be useful to detect multiple semantic meaning of the home photos.     

Unix环境下编译调试HD Photo

微软公司自行研发了HD Photo图片格式,HD Photo可以支持高达32 bit的色彩深度.在Windows系统中使用Cygwin工具构造Unix虚拟环境,配置编译HD Photo所需要的编译环境,然后用这个编译环境对HD Photo工具包内的编解码算法进行编译,并产生二进制可执行文件.通过可视化GDB工具Insight对可执行文件进行调试,可以用Insight连接终端设备并将可执行文件下载到终端设备上.     

国立北平图书馆拍摄及影印出版敦煌遗书史事钩沉

本文钩稽排比国家图书馆旧档中有关拍照影印敦煌遗书的档案文件,辅以其他资料,发覆掘隐,再现了国立北平图书馆20世纪30年代拍照并计划影印敦煌遗书的史实,认为此举不仅有力地推动了流失海外敦煌文献的回归,促进了中国早期敦煌学的发展,而且对今天流失海外的古籍文献的回归也具有借鉴意义。     

历史照片保存问题探析

历史照片比文字资料更加真实地记录与还原了历史,但是由于照片材质的特殊性,其保存更易受到外界环境的影响。国家图书馆不仅对馆藏历史照片分类保存,而且调整照片库房排架方式,严格选择与限定照片的装具,其馆藏历史照片的保存方式及保护方案值得借鉴和学习。     

Depicting Experiences

This paper argues that photography is a helpful tool in understanding the ways people experience the world. Five arguments are presented in order to support this statement, each built on the methodological idea that respondents are asked to take, or produce, their own pictures related to a particular phenomenon under investigation. The arguments are: new unconventional methods enhance educational inquiry; photos can serve as communication bridges between strangers; photography makes it easier to represent a situation; photos can be regarded as complex expressions of the photographer's relation to the world; finally, photos enhance the expressing of feelings. These arguments are further discussed in the context of outcomes of a study, which used photography to probe ecological understanding. It is concluded that a deliberate use of the methodology will enhance not only the way photos might be used in research but also enrich educational research aiming at capturing the way people experience and relate to the world surrounding them.
