Monopod
A monopod, also called a unipod, is a single staff or pole used to help support cameras, binoculars, rifles or other precision instruments in the field. Camera and imaging use The monopod allows a still camera to be held steadier, allowing the photographer to take sharp pictures at slower shutter speeds, and/or with longer focal length lenses. In the case of video, it reduces camera shake, and therefore most of the resulting small random movements. Monopods are easier to transport and quicker to set up than conventional tripods, making them preferable for on-the-go (OTG) photography. An OTG photographer is not able to carry a heavy, bulky tripod around, and when they see a potential shot, there is no time to bother with setting up a complicated tripod. A simple monopod is easy to carry, easy to set up, and enables the photographer to take advantage of the situation they are presented with, all while providing camera support to capture a clear, sharp image.

Tripod (photography)
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. Usage Tripods are used for both still and motion photography to prevent camera movement. They are necessary when slow-speed exposures are being made, or when lenses of extreme focal length are used, as any camera movement while the shutter is open will produce a blurred image. In the same vein, they reduce camera shake, and thus are instrumental in achieving maxim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bipod
A bipod is a V-shaped portable attachment that helps support and steady a device, usually a weapon such as a long gun or a mortar. The term comes from the Latin prefix ''bi-'' and Greek root ''pod'', meaning "two" and "foot" respectively. Bipods are designed to support the weight of the weapon's front portion and barrel, and provide significant stability against unwanted side-to-side movements (i.e. canting) while allowing free movements pivoting around the transverse axis ( pitching). Most modern bipods have foldable and/or telescoping legs, and allow some limited movements around the vertical axis ( panning) and even the longitudinal axis ( tilting). A bipod by itself, with only two supporting legs, is not completely stable and needs to be reinforced by at least one more point of support to be steady, especially against the horizontal shearing force from recoils. This third point of support is typically the buttstock that is firmly pushed/braced against the shooter's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finnstick
A finnstick is the name given by birdwatchers to a stick used to support a binoculars. The one end of the stick is steadily attached to the binocular while the other end rests against the belly. Finnsticks help to keep the binoculars steady especially when they are used for a prolonged time. In addition to keeping the image steady which allows for finer details of the object to be discerned, the use of the stick reduces muscle strain thus enabling longer viewing with less sore muscles afterwards. Some birdwatchers feel that the use of a finnstick does not markedly improve the viewer's ability to resolve detail, but rather improves viewing comfort and prevents premature fatigue. The finnstick is especially useful when watching migration (e.g. seabirds, raptors) when the horizon may be scanned literally for hours to find migrant birds. As the name implies the stick was invented by the Finns but is now also used in other countries, mainly in Europe. Alternative strategies for steadyi ...

Tripod
A tripod is a portable three-legged frame or stand, used as a platform for supporting the weight and maintaining the stability of some other object. The three-legged (triangular stance) design provides good stability against gravitational loads as well as horizontal shear forces, and better leverage for resisting tipping over due to lateral forces can be achieved by spreading the legs away from the vertical centre. Variations with one, two, and four legs are termed '' monopod'', ''bipod'', and ''quadripod'' (similar to a table). Etymology First attested in English in the early 17th century, the word ''tripod'' comes via Latin ''tripodis'' ( GEN of ''tripus''), which is the romanization of Greek (''tripous''), "three-footed" (GEN , ''tripodos''), ultimately from (''tri-''), "three times" (from , ''tria'', "three") + (''pous''), "foot". The earliest attested form of the word is the Mycenaean Greek , ''ti-ri-po'', written in Linear B syllabic script. Cultural use Many cu ...

Jacob's Staff
The term Jacob's staff is used to refer to several things, also known as cross-staff, a ballastella, a fore-staff, a ballestilla, or a balestilha. In its most basic form, a Jacob's staff is a stick or pole with length markings; most staffs are much more complicated than that, and usually contain a number of measurement and stabilization features. The two most frequent uses are: * in astronomy and navigation for a simple device to measure angles, later replaced by the more precise sextants; * in surveying (and scientific fields that use surveying techniques, such as geology and ecology) for a vertical rod that penetrates or sits on the ground and supports a compass or other instrument. The simplest use of a Jacob's staff is to make qualitative judgements of the height and angle of an object relative to the user of the staff. In astronomy and navigation In navigation the instrument is also called a cross-staff and was used to determine angles, for instance the angle between the ...

Shutter Speed
In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time. of a second will let half as much light in as . Introduction The camera's shutter speed, the lens's aperture or f-stop, and the scene's luminance together determine the amount of light that reaches the film or sensor (the exposure). Exposure value (EV) is a quantity that accounts for the shutter speed and the f-number. Once the sensitivity to light of the recording surface (either film or sensor) is set in numbers expressed in " ISOs" (ex: 200 ISO, 400 ISO), the light emitted by the scene photographed can be controlled through aperture and shutter-speed to match the film or sensor sensitivity to light. This will achieve a good exposure when all the details of the sce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selfie Stick
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. Some are connected to a smartphone via its jack plug, while others are tethered using Bluetooth controls. The connection between the device and the selfie stick lets the user decide when to take the picture or start recording a video by clicking a button located on the handle. Models designed for compact cameras have a mirror behind the viewscreen so that the shot can be lined up. In contrast to a monopod for stabilising a camera on the ground, a selfie stick's arm is thickest and stronges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trekking Pole
Trekking poles (also known as hiking poles, hiking sticks or walking poles) are a common hiking accessory that function to assist walkers with their rhythm, to provide stability, and reduce strain on joints on rough terrain. Description When in use, modern trekking poles resemble ski poles as they have many features in common, such as baskets at the bottom to prevent the pole sinking through unstable surfaces, and rubber-padded handles and wrist straps to strengthen holding grip. Their maximum length is usually 135 cm (54 inches), however, unlike ski poles, they are often made in two or three sections and can be extended and retracted as necessary for use and collapsed for storage or transport. When fully retracted it may be possible to attach them to a backpack. Some poles come with spring-loaded sections to aid walking under normal conditions and to reduce wrist strain, but such devices may only add unwanted weight and noise to the poles. They are usually made from lightweight a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brunton Compass
A Brunton compass, properly known as the Brunton Pocket Transit, is a precision compass made by Brunton, Inc. of Riverton, Wyoming. The instrument was patented in 1894 by Canadian-born geologist David W. Brunton. Unlike most modern compasses, the Brunton Pocket Transit utilizes magnetic induction damping rather than fluid to damp needle oscillation. Although Brunton, Inc. makes many other types of magnetic compasses, the Brunton Pocket Transit is a specialized instrument used widely by those needing to make accurate navigational and slope-angle measurements in the field. Users are primarily geologists, but archaeologists, environmental engineers, mining engineers and surveyors also make use of the Brunton's capabilities. The United States Army has adopted the Pocket Transit as the M2 Compass for use by crew-served artillery. Overview The Pocket Transit may be adjusted for declination angle according to one's location on the Earth. It is used to get directional degree measureme ...

Depth Of Field
The depth of field (DOF) is the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera. Factors affecting depth of field For cameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus. "Acceptably sharp focus" is defined using a property called the " circle of confusion". The depth of field can be determined by focal length, distance to subject, the acceptable circle of confusion size, and aperture. Limitations of depth of field can sometimes be overcome with various techniques and equipment. The approximate depth of field can be given by: : \text \approx \frac for a given circle of confusion (c), focal length (f), f-number (N), and distance to subject (u). As distance or the size of the acceptable circle of confusion increases, the depth of field increases; however, increasing the size ...
