n. 1. a device producing a bright flame, used especially as a signal or marker: a helicopter spotted a flare set off by the crew | a flare gun.

2. an upward and outward curve of a vessel’s bow, designed to throw the water outward when under way.

See the Introduction, Abbreviations and Pronunciation for further details.

The type of flare that is formed by reflections of the lens diaphragm in the lens elements is rarely important, as it is easily seen in the viewfinder of any camera with through-lens viewing.

Much more insidious is ‘veiling flare’, caused by stray light bouncing about inside the lens and the camera body. Some of this is reflected out through the lens; some is absorbed by baffles and blacking; and some ends up on the film, where it ‘fills’ the shadows, suppressing subtle shadow detail, flattening contrast, and reducing the overall brightness range of the image. This can be at its worst on an overcast day: it is much reduced in directional lighting, provided the directional light does actually shine directly on the front of the lens. The worst thing about veiling flare is that because it is uniform over the emulsion it has a greater effect on the shadows than on the mid-tones and highlights, giving an effect resembling underexposure in the print.

The difference between the brightness range of the subject and the brightness range of the projected image is expressed as a ‘flare factor’. For a modern, well-made bellows camera with a multicoated lens it can approach 1, i.e. no flare at all. But an old box camera with an uncoated lens and a poorly blacked interior may have a flare factor of 4 or more, so that (for example) a subject brightness range of 128 : 1 (seven stops) may be reduced to an image brightness range of 32 : 1 (five stops).

Flare is reduced by better coating; by the use of lens shades that are as deep as possible; by good blacking and baffling; and by the use of simple lenses with as few glass-air surfaces as possible.

Defining two words to dazzle your boating friends
If you want to impress fellow boaters with your nautical knowledge, arrange to drop two words into your casual conversation sometime: flare and flam. Comparatively few boaters know what flare is; even fewer have any idea what flam is.Flare is the outward, upward curve or slant of a vessel’s sides, from the waterline to the deck

Naval architect Ted Brewer’s graphic explanation of flam, flare, and tumblehome.

line. It’s usually referred to in connection with the bow of a boat. You could mention, for example, that your boat was designed with a good deal of flare to gradually increase buoyancy as she plunges into head seas.The reason flam is so little understood is partly because authorities are not always in agreement about its definition. Some define it as a part of flare. Flam, they say, is the exaggerated outward curve right at the top of the flare. It’s often incorporated into a boat’s hull to repel spray and keep her fore-deck dry in head seas. So you could say, for example, the flam on your boat was ideal for yesterday’s choppy conditions on the bay.In addition, a designer will sometimes give a boat flam to increase the width of the foredeck for some reason.However, naval architects such as Ted Brewer and Howard I. Chapelle, former Historian Emeritus in the Department of Industries of the U.S. Museum of History and Technology, Smithsonian Institute, hold that flam is the convex shape of the hull above the waterline, particularly noticeable in the forebody, where it imparts buoyancy when the vessel is heeled.That interesting word tumble-home, which is the inward, upward curve of a hull from the waterline up to deck level, is the exact opposite of flare, of course, but seems to be far better known and understood.

(DOD, NATO) The change in the flight path of an aircraft so as to reduce the rate of descent for touchdown.

IN BRIEF: n. - (baseball) a fly ball hit a short distance into the outfield; A short forward pass to a back who is running toward the sidelines; A device that produces a bright light for warning or illumination or identification;

i. A maneuver carried out just before touchdown to reduce the rate of descent, so that the aircraft settles on the runway smoothly and with the least amount of vertical speed. Normally referred to as flare-out.
ii. A magnesium candle supported by a small parachute, which was at one time carried by most aircraft operating at night. This flare was fired if it became necessary to force land. The burning flare produced sufficient light to enable a pilot to see the ground for making a landing. Flares are pyrotechnic devices used for signaling or to provide illumination.
iii. A cone-shaped expansion on the end of tubing. Tubing used in aircraft fluid lines flared at an angle of 37°.
iv. Infrared flares meant to deflect incoming infrared missiles.
v. A waveguide in which one or both transverse dimensions increase toward the aperture. Also called a horn.



vi. As it relates to aerial photography, light reaching the photosensitive emulsion, resulting from internal reflections within the lens, such as occur from a noncoated air-glass lens surface.
