Aerial photography (or airborne imagery ) is the taking of photographs from an aircraft or other airborne platforms. When taking motion pictures , it is also known as aerial videography .
85-554: Talbert "Ted" Abrams (August 17, 1895 – August 25, 1990) was an American photographer and aviator known as the "father of aerial photography ". Born in Tekonsha, Michigan , Abrams learned to fly at the Curtiss Aviation School while working as a mechanic for Curtiss . He was issued Fédération Aéronautique Internationale pilot's license number 282. The certificate was signed by Orville Wright . He joined
170-656: A Standard J-1 , fitted it with cameras, and founded the Abrams Aerial Survey Corporation (sold to Aerocon in 2003). Over the next few years, he formed the Abrams Instrument Corporation to develop better cameras and instruments for his work, and the Abrams Aircraft Corporation in 1937 to develop specially designed aircraft. He got his first income from aerial photography when he took a photo of

In the 1980s a small number of high-quality replica Doppel-Sport cameras were made by Rolf Oberländer. One was acquired in 1999 by the Swiss Camera Museum in Vevey. Modern technology allows extension of the principle to video cameras. In
425-572: A 624 square miles (1,620 km ) area in Palestine as an aid to correcting and improving maps of the Turkish front. This was a pioneering use of aerial photography as an aid for cartography . Lieutenants Leonard Taplin , Allan Runciman Brown , H. L. Fraser, Edward Patrick Kenny , and L. W. Rogers photographed a block of land stretching from the Turkish front lines 32 miles (51 km) deep into their rear areas. Beginning 5 January, they flew with
510-404: A balloon between Hammam-Lif and Grombalia . The first use of a motion picture camera mounted to a heavier-than-air aircraft took place on April 24, 1909, over Rome in the 3:28 silent film short, Wilbur Wright und seine Flugmaschine . The use of aerial photography rapidly matured during the war, as reconnaissance aircraft were equipped with cameras to record enemy movements and defenses. At
595-403: A balloon. As photographic techniques made further progress, at the end of the 19th century some pioneers placed cameras in unmanned flying objects. In the 1880s, Arthur Batut experimented with kite aerial photography . Many others followed him, and high-quality photographs of Boston taken with this method by William Abner Eddy in 1896 became famous. Amedee Denisse equipped a rocket with
680-416: A battery-powered camera designed for espionage pigeon photography; details of its use remain classified . The construction of sufficiently small and light cameras with a timer mechanism, and the training and handling of the birds to carry the necessary loads, presented major challenges, as did the limited control over the pigeons' position, orientation and speed when the photographs were being taken. In 2004,

In a short book published in 1909 Neubronner described five camera models: In a 1920 pamphlet, Neubronner described his last model as weighing slightly more than 40 grams (1.4 oz) and being capable of taking 12 exposures. In 2007, a researcher remarked that only little technical information is available about lenses, shutters and
850-850: A business with major contracts in Africa and Asia as well as in the UK. Operations began from the Stag Lane Aerodrome at Edgware, using the aircraft of the London Flying School. Subsequently, the Aircraft Manufacturing Company (later the De Havilland Aircraft Company ), hired an Airco DH.9 along with pilot entrepreneur Alan Cobham . From 1921, Aerofilms carried out vertical photography for survey and mapping purposes. During

Homing pigeons were used extensively in the 19th and early 20th centuries, both for civil pigeon post and as war pigeons . In the Franco-Prussian War of 1870, the famous pigeon post of Paris carried up to 50,000 microfilmed telegrams per pigeon flight from Tours into the besieged capital. Altogether 150,000 individual private telegrams and state dispatches were delivered. In an 1889 experiment of

Vertical photographs are often used to create orthophotos , alternatively known as orthophotomaps , photographs which have been geometrically "corrected" so as to be usable as a map. In other words, an orthophoto is a simulation of a photograph taken from an infinite distance, looking straight down to nadir . Perspective must obviously be removed, but variations in terrain should also be corrected for. Multiple geometric transformations are applied to
1105-481: A fighter escort to ward off enemy fighters. Using Royal Aircraft Factory BE.12 and Martinsyde airplanes, they not only overcame enemy air attacks, but also had to contend with 65 mph (105 km/h) winds, antiaircraft fire, and malfunctioning equipment to complete their task. The first commercial aerial photography company in the UK was Aerofilms Ltd, founded by World War I veterans Francis Wills and Claude Graham White in 1919. The company soon expanded into

Aerial photography was first practiced by the French photographer and balloonist Gaspard-Félix Tournachon , known as "Nadar" , in 1858 over Paris , France. However,
1275-409: A lower height. The Prussian War Ministry was interested, but some initial skepticism could only be overcome through a series of successful demonstrations. The pigeons proved relatively indifferent to explosions, but during battle a dovecote may need to be moved, and pigeons can take some time to orient to their new position. The problem of making carrier pigeons accept a displaced dovecote with only
1360-929: A mass of more than 20 kg are termed 'Large Model Aircraft' – within the UK, large model aircraft may only be flown in accordance with an exemption from the ANO, which must be issued by the CAA. Photographs taken at an angle are called oblique photographs . If they are taken from a low angle relative to the earth's surface, they are called low oblique and photographs taken from a high angle are called high or steep oblique . Vertical photographs are taken straight down. They are mainly used in photogrammetry and image interpretation . Pictures that will be used in photogrammetry are traditionally taken with special large format cameras with calibrated and documented geometric properties. Aerial photographs are often combined. Depending on their purpose it can be done in several ways, of which
1445-518: A minimum of retraining had been tackled with some success by the Italian army around 1880; the French artillery captain Reynaud solved it by raising the pigeons in an itinerant dovecote. There is no indication that Neubronner was aware of this work, but he knew there must be a solution as he had heard of an itinerant fairground worker who was also a pigeon fancier with a dovecote in his trailer . At
1530-563: A new "double sport" combining carrier pigeon fancying with amateur photography. (Neubronner later learned that his pigeon had been in the custody of a restaurant chef in Wiesbaden .) After successfully testing a Ticka watch camera on a train and whilst riding a sled, Neubronner began the development of a light miniature camera that could be fitted to a pigeon's breast by means of a harness and an aluminum cuirass . Using wooden camera models which weighed 30 to 75 grams (1.1 to 2.6 oz),
1615-597: A perception of depth that could aid in cartography and in intelligence derived from aerial images. The Royal Flying Corps recon pilots began to use cameras for recording their observations in 1914 and by the Battle of Neuve Chapelle in 1915, the entire system of German trenches was being photographed. In 1916 the Austro-Hungarian Monarchy made vertical camera axis aerial photos above Italy for map-making. The first purpose-built and practical aerial camera
1700-521: A practical test at a maneuver in Strasbourg , followed by the state's acquisition of the invention. These plans were thwarted by the outbreak of the war. Neubronner had to provide all his pigeons and equipment to the military, which tested them in the battlefield with satisfactory results, but did not employ the technique more widely. Instead, under the novel conditions of attrition warfare , war pigeons in their traditional role as pigeon post saw

Neubronner's mobile dovecote found its way to the Battle of Verdun , where it proved so advantageous that similar facilities were used on a larger scale in the Battle of the Somme . After the war, the War Ministry responded to Neubronner's inquiry to the effect that the use of pigeons in aerial photography had no military value and further experiments were not justified. The International Spy Museum in Washington D.C. includes
1955-468: A replica of a pigeon camera in its collection. Despite the War Ministry's position immediately after the First World War, in 1932 it was reported that the German army was training pigeons for photography, and that the German pigeon cameras were capable of 200 exposures per flight. In the same year, the French claimed that they had developed film cameras for pigeons as well as a method for having
2040-573: A sanatorium in nearby Falkenstein via pigeon post. He delivered urgent medications up to 75 grams (2.6 oz) by the same method, and positioned some of his pigeons with his wholesaler in Frankfurt to profit from faster deliveries himself. When one of his pigeons lost its orientation in fog and mysteriously arrived, well-fed, four weeks late, Neubronner was inspired with the playful idea of equipping his pigeons with automatic cameras to trace their paths. This thought led him to merge his two hobbies into

One of its first government contracts was an aerial survey of New Mexico to study soil erosion. A year later, Fairchild introduced a better high altitude camera with nine-lens in one unit that could take a photo of 600 square miles with each exposure from 30,000 feet. In 1939 Sidney Cotton and Flying Officer Maurice Longbottom of

Michel's plan to sell his camera to the Swiss Army failed, as he was unable to find a manufacturer to produce it in quantity; only about 100 of his cameras were constructed. After the outbreak of the Second World War Michel patented a shell and harness for the transport of items such as film rolls by carrier pigeon. Between 2002 and 2007 three of his cameras were auctioned by Christie's in London. The Musée suisse de l'appareil photographique at Vevey holds around 1,000 photographs taken for test purposes during

3315-540: The RAF were among the first to suggest that airborne reconnaissance may be a task better suited to fast, small aircraft which would use their speed and high service ceiling to avoid detection and interception. Although this seems obvious now, with modern reconnaissance tasks performed by fast, high flying aircraft, at the time it was radical thinking. They proposed the use of Spitfires with their armament and radios removed and replaced with extra fuel and cameras. This led to

In 1920, the Australian Milton Kent started using a half-plate oblique aero camera purchased from Carl Zeiss AG in his aerial photographic business. Another successful pioneer of the commercial use of aerial photography was the American Sherman Fairchild who started his own aircraft firm Fairchild Aircraft to develop and build specialized aircraft for high altitude aerial survey missions. One Fairchild aerial survey aircraft in 1935 carried unit that combined two synchronized cameras, and each camera having five six inch lenses with

The idea was briefly resurrected in the 1930s by a Swiss clockmaker , and reportedly also by the German and French militaries. Although war pigeons were deployed extensively during World War II , it is unclear to what extent, if any, birds were involved in aerial reconnaissance. The United States Central Intelligence Agency (CIA) later developed

5695-534: The hands of field commanders in record time. Frederick Charles Victor Laws started aerial photography experiments in 1912 with No.1 Squadron of the Royal Flying Corps (later No. 1 Squadron RAF ), taking photographs from the British dirigible Beta . He discovered that vertical photos taken with a 60% overlap could be used to create a stereoscopic effect when viewed in a stereoscope, thus creating

Orthophotos are commonly used in geographic information systems , such as are used by mapping agencies (e.g. Ordnance Survey ) to create maps. Once the images have been aligned, or "registered", with known real-world coordinates, they can be widely deployed. Large sets of orthophotos, typically derived from multiple sources and divided into "tiles" (each typically 256 x 256 pixels in size), are widely used in online map systems such as Google Maps .

To take an aerial photograph, Neubronner carried a pigeon to a location up to about 100 kilometres (60 mi) from its home, where it was equipped with a camera and released. The bird, keen to be relieved of its burden, would typically fly home on a direct route, at a height of 50 to 100 metres (160 to 330 ft). A pneumatic system in the camera controlled

Under these regulations, unmanned remotely piloted aircraft for commercial are referred to as Remotely Piloted Aircraft Systems (RPAS), whereas radio-controlled aircraft for recreational purposes are referred to as model aircraft. Under CASR Part 101, businesses/persons operating remotely piloted aircraft commercially are required to hold an operator certificate, just like manned aircraft operators. Pilots of remotely piloted aircraft operating commercially are also required to be licensed by
6375-403: The regulations and from September 29, 2016, drones under 2 kg (4.4 lb) may be operated for commercial purposes. 2006 FAA regulations grounding all commercial RC model flights have been upgraded to require formal FAA certification before permission is granted to fly at any altitude in the US. June 25, 2014, The FAA, in ruling 14 CFR Part 91 [Docket No. FAA–2014–0396] "Interpretation of
6460-527: The size and the characteristic launching mechanisms for both the V-1 flying bomb and the V-2 rocket . Cotton also worked on ideas such as a prototype specialist reconnaissance aircraft and further refinements of photographic equipment. At the peak, the British flew over 100 reconnaissance flights a day, yielding 50,000 images per day to interpret. Similar efforts were taken by other countries. Vertical aerial photography
6545-423: The speed of the photographic media, but reported that Neubronner obtained the film for his panoramic camera from ADOX . For this camera he estimated a film speed of ISO 25/15° – 40/17° and a shutter speed of 1/60 s – 1/100 s. The film was cut to the format 30 mm × 60 mm and bent into a concave shape to prevent unnecessary distortion due to the half-circle movement of
6630-407: The start of the conflict, the usefulness of aerial photography was not fully appreciated, with reconnaissance being accomplished with map sketching from the air. Germany adopted the first aerial camera, a Görz , in 1913. The French began the war with several squadrons of Blériot observation aircraft equipped with cameras for reconnaissance. The French Army developed procedures for getting prints into
6715-610: The technique at the 1909 Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the 1910 and 1911 Paris Air Shows . Initially, the military potential of pigeon photography for aerial reconnaissance appeared interesting. Battlefield tests in World War I provided encouraging results, but the ancillary technology of mobile dovecotes for messenger pigeons had
6800-404: The time delay before a photograph was taken. To accommodate the burdened pigeon, the dovecote had a spacious, elastic landing board and a large entry hole. According to Neubronner, there were a dozen different models of his camera. In 1907 he had sufficient success to apply for a patent. Initially his invention "Method of and Means for Taking Photographs of Landscapes from Above" was rejected by
6885-417: The use of similar orthophotos for deriving new map data. Google Earth overlays orthophotos or satellite imagery onto a digital elevation model to simulate 3D landscapes. Aerial photography may be labeled as either "leaf-off" or on "leaf-on" to indicate whether deciduous foliage is in the photograph. Leaf-off photographs show less foliage or no foliage at all, and are used to see the ground and things on
6970-568: Was a failure. In 1978 the Swiss magazine L'Illustré printed an aerial photograph of a street in Basel , taken by a pigeon of Febo de Vries-Baumann equipped with a camera with a hydraulic mechanism. In 2002–2003 the performance artist and pigeon fancier Amos Latteier experimented with pigeon photography using Advanced Photo System (APS) and digital cameras and turned the results into "PowerPointillist" lecture performances in Portland, Oregon . In
7055-457: Was assigned to the Swiss Army 's carrier pigeons service in 1931, and in 1933 he began work on adapting Neubronner's panoramic camera to 16 mm film , and improving it with a mechanism to control the delay before the first exposure and to transport the film between exposures. Michel's camera, patented in 1937, weighed only 70 grams (2.5 oz), and may have been one of the first to have
7140-497: Was at least partially motivated by the prospect of military applications. At the time photographic aerial reconnaissance was possible but cumbersome, as it involved balloons , kites or rockets . The Wright brothers ' successful flight in 1903 presented new possibilities, and surveillance aircraft were introduced and perfected during the First World War. But pigeon-based photography, despite its practical difficulties, promised to deliver complementary, detailed photographs taken from
7225-622: Was invented by Captain John Moore-Brabazon in 1915 with the help of the Thornton-Pickard company, greatly enhancing the efficiency of aerial photography. The camera was inserted into the floor of the aircraft and could be triggered by the pilot at intervals. Moore-Brabazon also pioneered the incorporation of stereoscopic techniques into aerial photography, allowing the height of objects on the landscape to be discerned by comparing photographs taken at different angles.
