Drone Photography
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. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs or "drones"), balloons, blimps and dirigibles, rockets, pigeons, kites, or using action cameras while skydiving or wingsuiting. Handheld cameras may be manually operated by the photographer, while mounted cameras are usually remotely operated or triggered automatically. Aerial photography typically refers specifically to bird's-eye view images that focus on landscapes and surface objects, and should not be confused with air-to-air photography, where one or more aircraft are used as chase planes that "chase" and photograph other aircraft in flight. Elevated photography can also produce bird's-eye images closely resembling aerial photography (despite not actually being aerial shots) when te ...

Action Camera
An action camera or action cam is a digital camera designed for recording action while being immersed in it. Action cameras are therefore typically compact and rugged, and waterproof at surface-level. They typically use CMOS image sensors, and can take photos in burst mode and time-lapse mode as well as record high-definition video (as of 2019, mid-range to high-end action cameras can record 4K video at 60 fps). Slow-motion video recording at 120 or 240 fps is also a common feature. Overview The camera is typically worn or mounted in such a way that it can shoot from the point of view of the shooter. Some examples of common places to mount an action camera are on a hat or helmet, on the chest, or on the handlebars of a bike or similar vehicle. They may also be mounted on a tripod or on a monopod for handheld use. An action camera is usually designed to require minimal interaction once recording has begun, as this allows continuous capture of the action without having to in ...

Cable-suspended Camera System
A cable-suspended camera system is a system of cables above or along an area to be filmed or videoed, over or along which an attached camera head travels to achieve required camera angles. There are two broad types cable-suspended camera systems: fixed-cable and moving-cable types. Fixed-cable type In fixed-cable type cable-suspended camera systems, the cable is attached at fixed anchor points and a motorized camera head travels along the fixed cable. This kind of system can be advantageous over longer distances and where it might be difficult to set up winches with moving cables, or in no fly zones. Some use cases have a camera head running along the ground in trolley mode for a kind of tracking shot. In recent years, fixed-cable suspended camera systems has become popular for professional live TV broadcast and film production to shoot sport and entertainment events. A widely used system is the Defy Dactylcam, which travels along the cable with a motor, and the Newton stabil ...

Overlook
A scenic viewpoint – also called an observation point, viewpoint, viewing point, vista point, lookout, scenic overlook,These terms are more commonly used in North America. etc. – is an elevated location where people can view scenery (often with binoculars) and photograph it. Scenic viewpoints may be created alongside scenic routes or mountain roads, often as simple turnouts or lay-bys where motorists can pull over onto pavement, gravel, or grass on the right-of-way. Many viewpoints are larger, having parking areas, while some (typically on larger highways) are off the road completely. Viewing points may also be found on hill or mountain tops or on rocky spurs overlooking a valley and reached via a hiking trail. They may be protected by railings to protect the public or be enhanced by a viewing tower designed to elevate visitors above the surrounding terrain or trees in order to offer panoramic views. Overlooks are frequently found in national parks, and in the U.S. along n ...

Telephoto
A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a ''telephoto group'' that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as ''telephoto lenses'', although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group. Telephoto lenses are sometimes broken into the further sub-types of short telephoto (85–135 mm in 35 mm film format), medium telephoto: (135–300 mm in 35 mm film format) and super telephoto (over 300 mm in 35 mm film format) . Construction In contrast to a telephoto lens, for any given focal lengt ...

Elevated Photography
Elevated photography is the process of taking aerial photos using a telescoping pole or mast, or other aerial or elevated support systems, to emulate aerial photographs, or video, taken from a commercially licensed aircraft. In some ways, elevated photography is more flexible than imagery taken from a commercial aircraft, or an orbiting satellite, in that it is capable of getting highly detailed images, from a birds eye view. This method allows for image collection that offers synoptic timelines - making this process a useful tool for construction management, litigation, accident investigation, real estate promotion and much more. The price and flexibility of elevated imaging is generally quite reasonable, and it includes varying degrees of compatibility with related engineering-quality software. Because it does not involve the use of a manned commercial aircraft, the overhead and costs associated with elevated photography should be much lower. Elevated photography has been aroun ...

Chase Plane
A chase plane is an aircraft that "chases" a "subject" aircraft, spacecraft or rocket, for the purposes of making real-time observations and taking air-to-air photographs and video of the subject vehicle during flight. Background Safety can be one function of a chase plane; others are to photograph or video the target vehicle, or to collect engineering data from it. Chase planes may be used during flight tests, and for many years the best way to ensure the safety of an experimental aircraft was to fly alongside it and observe the flight. This "chase" airplane's crew would keep a constant lookout for problems with the "subject" or test aircraft, and if problems did arise, they would provide warnings and critical information to the test aircraft's crew, and to the mission controllers on the ground. They would also monitor the surrounding airspace for other aircraft that could pose a hazard to the flight, either by straying into their flightpath or threatening any kind of secre ...

Air-to-air Photography
Air-to-air photography is the art of photographing aircraft in the air, by using another aircraft as a photo platform. It is especially popular among military aircraft photographers and aerobatic pilots flying at air shows. Air-to-air photography requires special skills and experience, as the photo platform and target aircraft often fly low level while under moderate to high G-forces. Looking through his camera, the photographer usually sits looking sideways while the aircraft manoeuvres through the sky, often resulting in airsickness and making air-to-air photography even more challenging. The subject aircraft is photographed while both aircraft are in flight. This allows the photographer to position the subject in specific locations and angles to get the most desirable shot. Some things that must be considered to achieve best results are lighting and background. Proper lighting is achieved through correct placement of the aircraft relative to the sun, and is accomplished flying ...

Earth Surface
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar energy i ...

Landscape
A landscape is the visible features of an area of land, its landforms, and how they integrate with natural or man-made features, often considered in terms of their aesthetic appeal.''New Oxford American Dictionary''. A landscape includes the physical elements of geophysically defined landforms such as (ice-capped) mountains, hills, water bodies such as rivers, lakes, ponds and the sea, living elements of land cover including indigenous vegetation, human elements including different forms of land use, buildings, and structures, and transitory elements such as lighting and weather conditions. Combining both their physical origins and the cultural overlay of human presence, often created over millennia, landscapes reflect a living synthesis of people and place that is vital to local and national identity. The character of a landscape helps define the self-image of the people who inhabit it and a sense of place that differentiates one region from other regions. It is the dyn ...

Bird's-eye View
A bird's-eye view is an elevated view of an object or location from a very steep viewing angle, creating a perspective as if the observer were a bird in flight looking downwards. Bird's-eye views can be an aerial photograph, but also a drawing, and are often used in the making of blueprints, floor plans and maps. Before crewed flight was common, the term "bird's eye" was used to distinguish views drawn from direct observation at high vantage locations (e.g. a mountain or tower), from those constructed from an imagined bird's perspectives. Bird's eye views as a genre have existed since classical times. They were significantly popular in the mid-to-late 19th century in the United States and Europe as photographic prints. Terminology The terms aerial view and aerial viewpoint are also sometimes used synonymous with bird's-eye view. The term ''aerial view'' can refer to any view from a great height, even at a wide angle, as for example when looking sideways from an airplan ...

Remote Operation
Teleoperation (or remote operation) indicates operation of a system or machine at a distance. It is similar in meaning to the phrase "remote control" but is usually encountered in research, academia and technology. It is most commonly associated with robotics and mobile robots but can be applied to a whole range of circumstances in which a device or machine is operated by a person from a distance. The term ''teleoperation'' is in use in research and technical communities as a standard term for referring to operation at a distance. This is as opposed to ''telepresence'' which is a less standard term and might refer to a whole range of existence or interaction that include a remote connotation. History The 19th century saw many inventors working on remotely operated weapons (torpedoes) including prototypes built by John Louis Lay (1872), John Ericsson (1873), Victor von Scheliha (1873), and the first practical wire guided torpedo, the Brennan torpedo, patented by Louis Brenna ...
