A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.
In electronics, a remote control is an electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other digital home media appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for the user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside.
Kite aerial photography (KAP) is a type of photography. A camera is lifted using a kite and is triggered either remotely or automatically to take aerial photographs. The camera rigs can range from the extremely simple, consisting of a trigger mechanism with a disposable camera, to complex apparatus using radio control and digital cameras. On some occasions it can be a good alternative to other forms of aerial photography.
The Bulb setting on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button. The Bulb setting is distinct from shutter's Time (T) setting, which is an alternate-action mode where the shutter opens when the shutter-release button is pressed and released once, and closes when the button is actuated again.
In photography, a tripod is a portable device used to support, stabilize and elevate a camera, a flash unit, or other videographic or observational/measuring equipment. All photographic tripods have three legs and a mounting head to couple with a camera. The mounting head usually includes a thumbscrew that mates to a female-threaded receptacle on the camera, as well as a mechanism to be able to rotate and tilt the camera when it is mounted on the tripod. Tripod legs are usually made to telescope, in order to save space when not in use. Tripods are usually made from aluminum, carbon fiber, steel, wood or plastic.
In photography, through-the-lens metering refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure, it can also be used to control the amount of light emitted by a flash unit connected to the camera.
A hot shoe is a mounting point on the top of a camera to attach a flash unit and other compatible accessories. It takes the form of an angled metal bracket surrounding a metal contact point which completes an electrical connection between camera and accessory for standard, brand-independent flash synchronization.
Aviation photography is the act of taking images of aircraft, either in flight, or on the ground. Types of aviation photography include air-to-air, ground-to-air, ground-static, and remote photography. Military aviation photography, especially air-to-air, requires additional skills, as the photo and target aircraft often fly at velocities of over Mach 1, while under moderate to high G.
Wildlife photography is a genre of photography concerned with documenting various forms of wildlife in their natural habitat.
The following outline is provided as an overview of and topical guide to photography:
Nature photography is a wide range of photography taken outdoors and devoted to displaying natural elements such as landscapes, wildlife, plants, and close-ups of natural scenes and textures. Nature photography tends to put a stronger emphasis on the aesthetic value of the photo than other photography genres, such as photojournalism and documentary photography.
Sports photography refers to the genre of photography that covers all types of sports.
Most digital cameras support the ability to choose among a number of configurations, or modes for use in various situations. Professional DSLR cameras provide several manual modes; consumer point-and-shoot cameras emphasize automatic modes; amateur prosumer cameras often have a wide variety of both manual and automatic modes.
Fireworks photography is the process of taking photographs of fireworks at night. It is a type of night photography, specifically using available light of the fireworks instead of artificial light. Without using the flash on the camera, the photographer often exposes the image for a period of time, known as long exposure. Brighter fireworks sometimes support shorter exposure times.
A camera trap is a camera that is automatically triggered by motion in its vicinity, like the presence of an animal or a human being. It is typically equipped with a motion sensor – usually a passive infrared (PIR) sensor or an active infrared (AIR) sensor using an infrared light beam.
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.
Landscape photography shows the spaces within the world, sometimes vast and unending, but other times microscopic. Landscape photographs typically capture the presence of nature but can also focus on human-made features or disturbances of landscapes. Landscape photography is done for a variety of reasons. Perhaps the most common is to recall a personal observation or experience while in the outdoors, especially when traveling. Others pursue it particularly as an outdoor lifestyle, to be involved with nature and the elements, some as an escape from the artificial world.
The Nikon D5100 is a 16.2-megapixel DX-format DSLR F-mount camera announced by Nikon on April 5, 2011. It features the same 16.2-megapixel CMOS sensor as the D7000 with 14-bit depth, while delivering Full HD 1080p video mode at either 24, 25 or 30 fps. The D5100 is the first Nikon DSLR to offer 1080p video at a choice of frame rates; previous Nikon DSLRs that recorded 1080p only did so at 24 fps. It replaced the D5000 and was replaced by the D5200.
A selfie stick is used to take photographs or video by positioning a digital camera device, typically a smartphone, beyond the normal range of the arm. This allows for shots to be taken at angles and distances that would not have been possible with the human arm by itself. The sticks are typically extensible, with a handle on one end and an adjustable clamp on the other end to hold the device in place. As their name suggests, they are most commonly used for taking selfies with camera phones.
Cactus is a brand owned by Harvest One Limited, a Hong Kong company specialized in the design and engineering of photographic wireless lighting equipment including wireless flash triggers, wireless flashes, portable softboxes and studio umbrellas. Its headquarters is in Tuen Mun, Hong Kong.
