Rephotography
Rephotography is the act of repeat photography of the same site, with a time lag between the two images; a diachronic, "then and now" view of a particular area. Some are casual, usually taken from the same view point but without regard to season, lens coverage or framing. Some are very precise and involve a careful study of the original image. Rephotography and photogrammetry in the sciences Since the 1850s techniques were developed for surveying and scientific study, especially in systems (Paganini, 1880; Deville, 1889; Finsterwalder, 1890) of photogrammetry in which precise measurements made from triangulation of points in numbers of photographic records are made in order to track changes in ecological systems. Rephotography continues to be used by the scientific world to record incremental or cyclical events (of erosion, or land rehabilitation, or glacier flow for example), or to measure the extent of sand banks in a river, or other phenomena which change slowly over tim ...

Sebastian Finsterwalder
Sebastian Finsterwalder (4 October 1862 – 4 December 1951) was a German mathematician and glaciologist. Acknowledged as the "father of glacier photogrammetry"; he pioneered the use of repeat photography as a temporal surveying instrument in measurement of the geology and structure of the Alps and their glacier flows. The measurement techniques he developed and the data he produced are still in use to discover evidence for climate change. Life Sebastian Finsterwalder was born 4 October 1862 in Rosenheim, son of Johann Nepomuk Finsterwalder, a master baker from Antdorf near Weilheim, Upper Bavaria, and Anna Amman of Rosenheim. He died 4 December 1951 in Munich). He was a Bavarian mathematician and surveyor. In 1892 he married Franziska Mallepell (d. 1953) from Brixen, South Tyrol. Their two sons worked in similar fields; Richard Finsterwalder (1899-1963), Professor at the Technical University in Hanover and Munich, and Ulrich Finsterwalder (1897-1988), a civil engineer.

Time-lapse Photography
Time-lapse photography is a technique in which the frequency at which film frames are captured (the frame rate) is much lower than the frequency used to view the sequence. When played at normal speed, time appears to be moving faster and thus ''lapsing''. For example, an image of a scene may be captured at 1 frame per second but then played back at 30 frames per second; the result is an apparent ''30 times'' speed increase. Similarly, film can also be played at a much lower rate than at which it was captured, which slows down an otherwise fast action, as in slow motion or high-speed photography. Processes that would normally appear subtle and slow to the human eye, such as the motion of the sun and stars in the sky or the growth of a plant, become very pronounced. Time-lapse is the extreme version of the cinematography technique of ''undercranking''. Stop motion animation is a comparable technique; a subject that does not actually move, such as a puppet, can repeatedly be move ...

William Notman
William Notman (8 March 1826 – 25 November 1891) was a Scottish-Canadian photographer and businessman. The Notman House in Montreal was his home from 1876 until his death in 1891, and it has since been named after him. Biography Notman was born in Paisley, Scotland, in 1826, and he moved to Montreal in the summer of 1856. An amateur photographer, he quickly established a flourishing professional photography studio on Bleury Street, a location close to Montreal's central commercial district. His first important commission was the documentation of the construction of the Victoria Bridge across the St. Lawrence River. The bridge opened with great fanfare in 1860, attended by the Prince of Wales and Notman's camera. The gift to the prince of a maple box containing Notman's photographs of the construction of the bridge and scenes of Canada East and Canada West so pleased Queen Victoria that, according to family tradition, she named him "Photographer to the Queen."

Photographic Techniques
Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...

1850s Introductions
Year 185 ( CLXXXV) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Lascivius and Atilius (or, less frequently, year 938 ''Ab urbe condita''). The denomination 185 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Nobles of Britain demand that Emperor Commodus rescind all power given to Tigidius Perennis, who is eventually executed. * Publius Helvius Pertinax is made governor of Britain and quells a mutiny of the British Roman legions who wanted him to become emperor. The disgruntled usurpers go on to attempt to assassinate the governor. * Tigidius Perennis, his family and many others are executed for conspiring against Commodus. * Commodus drains Rome's treasury to put on gladiatorial spectacles and confiscates property to suppor ...

Landscape History
Landscape history is the study of the way in which humanity has changed the physical appearance of the environment – both present and past. It is sometimes referred to as landscape archaeology. It was first recognised as a separate area of study during the 20th century and uses evidence and approaches from other disciplines including archaeology, architecture, ecology, aerial photography, rephotography, local history and historical geography. Origin and scope In England, landscape history emerged as an academic discipline following the publication of ''The Making of the English Landscape'' by W. G. Hoskins in 1955, although some topics that are now considered part of landscape history had been identified earlier. Darby, for example, gives many early examples of regional characterisation of landscapes. Following Hoskins, landscape history expanded in various directions. There are published landscape histories of a number of English counties. Other authors have studied the landsc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Melbourne
Melbourne ( ; Boonwurrung/Woiwurrung: ''Narrm'' or ''Naarm'') is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in both Australia and Oceania. Its name generally refers to a metropolitan area known as Greater Melbourne, comprising an urban agglomeration of 31 local municipalities, although the name is also used specifically for the local municipality of City of Melbourne based around its central business area. The metropolis occupies much of the northern and eastern coastlines of Port Phillip Bay and spreads into the Mornington Peninsula, part of West Gippsland, as well as the hinterlands towards the Yarra Valley, the Dandenong and Macedon Ranges. It has a population over 5 million (19% of the population of Australia, as per 2021 census), mostly residing to the east side of the city centre, and its inhabitants are commonly referred to as "Melburnians". The area of Melbourne has been home to Aboriginal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structure From Motion
Structure from motion (SfM) is a photogrammetric range imaging technique for estimating three-dimensional structures from two-dimensional image sequences that may be coupled with local motion signals. It is studied in the fields of computer vision and visual perception. In biological vision, SfM refers to the phenomenon by which humans (and other living creatures) can recover 3D structure from the projected 2D (retinal) motion field of a moving object or scene. Principle Humans perceive a great deal of information about the three-dimensional structure in their environment by moving around it. When the observer moves, objects around them move different amounts depending on their distance from the observer. This is known as motion parallax, and from this depth information can be used to generate an accurate 3D representation of the world around them. Finding structure from motion presents a similar problem to finding structure from stereo vision. In both instances, the correspo ...
