With increasingly accessible camera technology, crowdsourced public media projects abound like never before. Such projects often seek to secure a snapshot of a single day in order to establish communities and create visual time capsules for the future. Mass Photography: Collective Histories of Everyday Life assesses the potential of these popular moment-in-time projects by examining their current day prevalence and their historical predecessors. Through archival research and interviews with organisers and participants, it examines, for the first time, the vast photographic collections resulting from such projects, analysing their structures and systems, their aims and objectives, and their claims and promises. The central case study is the 55,000 photographs submitted to One Day for Life in 1987, which aimed, in its own time, to be ‘the biggest photographic event the world had ever seen’.
An empirical analysis was performed on data for 2000 sporadic meteors. A bimodal log-normal equation was found for unaccelerated velocity distribution, by empirical curve fitting to match observed velocity distributions for meteoroids within 10 ranges of mass with due regard to failure of observation of faint meteors. An exponent of -1.34 was confirmed in the equation for cumulative influx rate of meteoroids relative to mass. An exponent of -3.87 was established for meteoroid velocity relative to Earth's atmosphere as used in an earlier weighting factor for correction of biasing effects of velocity and mass. Earlier theoretical results were closely approximated.
"John Ingledew: Photography provides a basic introduction for students across the visual arts. This accessible, inspirational guide to creative photography explores the subjects and themes that have always obsessed photographers and explains technique in a clear and simple way. Embracing the whole spectrum of photography from traditional to digital, it introduces the work of the masters of the art as well as showing fresh, dynamic images created by young photographers from all over the world. An essential resource, the book also provides a valuable overview of careers in photography and a comprehensive reference section, including a glossary of technical vocabulary."--BOOK JACKET.
