The Helicam is a remote-controlled mini helicopter used to obtain aerial pictures or motion images using video, still or motion film cameras [1] . The remote controlled camera mount system allows pan, tilt and roll movements. A wireless onboard video transmitter downlinks the live signal to the camera operator, images can be recorded on board, on the ground or both. The system is controlled by two operators with independent controls: the helicam pilot and camera operator [2] .
One of the characteristics of the helicam is the flexibility and small size. The system can be flown practically everywhere providing a small spot of about 4 square meters is available to take off and land. Flight endurance ranges from 15 to 30 minutes, refueling can be done in seconds.
Helicams are used in film [3] , sports [4] and a variety of media [5] .
In filmmaking and video production, a crane shot is a shot taken by a camera on a moving crane or jib. Filmmaker D. W. Griffith created the first crane for his 1916 epic film Intolerance, with famed special effects pioneer Eiji Tsuburaya later constructing the first iron camera crane which is still adapted worldwide today. Most cranes accommodate both the camera and an operator, but some can be moved by remote control. Crane shots are often found in what are supposed to be emotional or suspenseful scenes. One example of this technique is the shots taken by remote cranes in the car-chase sequence of the 1985 film To Live and Die in L.A. Some filmmakers place the camera on a boom arm simply to make it easier to move around between ordinary set-ups.
An unmanned aerial vehicle (UAV), or unmanned aircraft system (UAS), commonly known as a drone, is an aircraft with no human pilot, crew, or passengers on board. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include aerial photography, area coverage, precision agriculture, forest fire monitoring, river monitoring, environmental monitoring, policing and surveillance, infrastructure inspections, smuggling, product deliveries, entertainment, and drone racing.
Steadicam is a brand of camera stabilizer mounts for motion picture cameras invented by Garrett Brown and introduced in 1975 by Cinema Products Corporation. The Steadicam brand was acquired by Tiffen in 2000. It was designed to isolate the camera from the camera operator's movement, keeping the camera motion separate and controllable by a skilled operator.
Telerobotics is the area of robotics concerned with the control of semi-autonomous robots from a distance, chiefly using television, wireless networks or tethered connections. It is a combination of two major subfields, which are teleoperation and telepresence.
Aerial photography is the taking of photographs from an aircraft or other airborne platforms. When taking motion pictures, it is also known as aerial videography.
A camera operator, or depending on the context cameraman or camerawoman, is a professional operator of a film camera or video camera as part of a film crew. The term "cameraman" does not necessarily imply that a male is performing the task.
Motion capture is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots. In films, television shows and video games, motion capture refers to recording actions of human actors and using that information to animate digital character models in 2D or 3D computer animation. When it includes face and fingers or captures subtle expressions, it is often referred to as performance capture. In many fields, motion capture is sometimes called motion tracking, but in filmmaking and games, motion tracking usually refers more to match moving.
A professional video camera is a high-end device for creating electronic moving images. Originally developed for use in television studios or with outside broadcast trucks, they are now also used for music videos, direct-to-video movies, corporate and educational videos, wedding videos, among other uses. Since the 2000s, most professional video cameras are digital.
A camera phone is a mobile phone that is able to capture photographs and often record video using one or more built-in digital cameras. It can also send the resulting image wirelessly and conveniently. The first commercial phone with a color camera was the Kyocera Visual Phone VP-210, released in Japan in May 1999.
A high-speed camera is a device capable of capturing moving images with exposures of less than 1/1 000 second or frame rates in excess of 250 frames per second. It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion. Early high-speed cameras used photographic film to record the high-speed events, but have been superseded by entirely electronic devices using an image sensor, typically recording over 1 000 frames per second onto DRAM, to be played back slowly to study the motion for scientific study of transient phenomena.
Time-lapse photography is a technique in which the frequency at which film frames are captured 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.
Videography involves capturing moving images on electronic media, and can include streaming media. It encompasses both video production and post-production methods. Historically Videography was considered the video counterpart to cinematography, which involved recording moving images on film stock. However, with the advent of digital video recording in the late 20th century, the distinction between the two has become less clear as both use similar intermediary mechanisms. Today, any video work can be referred to as videography, while commercial motion picture production is typically termed Cinematography.
Video assist is a system used in filmmaking that allows filmmakers to view and distribute a video version of a take immediately after it is filmed. On set, the location where the assist is reviewed is called a video village.
High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive frames. High-speed photography can be considered to be the opposite of time-lapse photography.
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.
The Nikon D90 is a 12.3-megapixel digital single-lens reflex camera (DSLR) model announced by Nikon on August 27, 2008. It is a prosumer model that replaces the Nikon D80, fitting between the company's entry-level and professional DSLR models. It has a Nikon DX format crop sensor.
A unit still photographer creates still photos specifically for use in publicity and marketing of feature films and television productions. In addition to creating photographs for the promotion of a film, the still photographer contributes daily to the filming process by creating set stills. With these, the photographer is careful to record all details of the cast wardrobe, set appearance and background.
A television production truck or OB van is a small mobile production control room to allow filming of events and video production at locations outside a regular television studio. They are used for remote broadcasts, outside broadcasting (OB), and electronic field production (EFP). Some require a crew of as many as 30 people, with additional trucks for additional equipment as well as a satellite truck, which transmits video back to the studio by sending it up through a communications satellite using a satellite dish, which then transmits it back down to the studio. Alternatively, some production trucks include a satellite transmitter and satellite dish for this purpose in a single truck body to save space, time and cost.
A camera stabilizer, or camera-stabilizing mount, is a device designed to hold a camera in a manner that prevents or compensates for unwanted camera movement, such as "camera shake".
In cinematography, remote heads, also known as 'hot' heads, or robos are motorized mechanical and/or electronic devices that are used as a mount for film, video or digital cinema cameras and can be controlled from a distance. In most cases this refers to control not only of the physical orientation of the camera body, such as pan (horizontal), tilt (vertical), roll, but also control over many or all camera functions – focus, zoom, color balance, gamma correction, camera menus and other related functions.
