Aperture Aperture
Found in most of the lenses which is a circular space in the center axis of the lens, control the amount of light that reflect the lens with the exception of simple cameras, as the size of the opening number to the variable focal length calibration.
Priority for the opening Aperture priorityA term used to describe the system in some automatic exposure cameras, where the photographer to choose the slot Adioa, while the shutter speed is set the appropriate aperture for this automatically, exposing the film to be in line with the amount of light entering it.
Situation (b) B-settingSymbol engraved on the shutter ring and indicates that the shutter will be open as long as the shutter button pressed.
Effacement BlurAreas in the image is clear, by the movement of the subject or vibration camera or focus focal vague or aberration optical lens, and is usually the proper way to unintended and undesirable, but can be used in the effects of creative, and is one of the main methods in the art sense of the movement.There are two main ways to use the proper way, one choice of shutter speed is too slow to Tgdmad movement subject which the cause of the obliteration, and the second to move or rotate the camera while moving the subject, so the subject is sharp the focus while the background blurred, and this depends on the shutter speed selected and then the degree of effacement desired.
Depth of field or field Depth of fieldIs the distance between the nearest and farthest point on the subject, so forming a sharp details for the imagination to focus length, and depth of field varies depending on the Amoaml the following:1 - the distance from the point of focus to the lens focal length (the shorter the distance increased the shallower depth of field).2 - the size of the aperture (the smaller the aperture deepened Almdian).3 - Tabad focal length of the lens (the larger the focal length diminished depth of field).And the scope of sharpness behind the point Altbir be greater than those at the top of the point.
Diffused light diffused lightAre those that have lost light intensity due to reflection or through a transparent material, and spread the optical light reduces glare and eliminates annoying shadows, and is used in photographing people.
Publisher DiffuserAny material that could spread the light and increase the area light source.
Exposure ExposureIn the term imaging is the amount of light a total of up to sensitive material to light (Slot sensitive) to form on the fantasy potential, depends exposure to preeminence the subject and the amount of light that reach this layer, and is Setting density of light by the aperture size and the time by the shutter.
Filter the candidateTransparent material of colored glass or gelatin or acetate, Tsthaddm in the absorption or entry into force of a particular molecule of light passing through it or to change the color or degree of influence in the light when he moved or distortion of the imagination.
Focal point Focus CenterIs the point where it intersects the optical axis with the focal plane, at which point it meets the optical radiation of topics far and are implemented through the lens. Intersection and this gives a sharp image in the focus when the lens is to develop indefinitely.
The focus \ Altbar FocusIs to adjust the lens to the distance of the film to become the subject sharply on the film, the cameras single-lens reflex is adjusted Altpaor rotate the lens manually or automatically, I'm in the cameras large usually Maindz Altpaor move the paintings front of the lens compared to the back panel of the film and related Mounfaj.
Freezing motion to freeze the movementIn the style of mobile imaging subject is sharp and Altpaor Mtmos, using a fast speed or lighting Gulf topic Bafilash mail.

Rotate the camera PanningIs a technique in the performance of running the camera and follow the movement of the subject, this method is usually used in the production of fiction of the subject sharp while the background is blurred.
Perspective PerspectiveWay in the display of objects three-dimensional surface de dimensions to give a sense of practical depth, and can be accessed in photography decrease size and convergence of lines and distance, and this is called perspective linear, either intervention shapes and change the distance the truth is called the perspective of air, and the choice of viewing angle in determining the impact of perspective is considered to be difficult, as the choice of the lens is considered an important work, Valadsat long focal length, while pushing the rear corner Aladsatwasah have the opposite effect.

Law Exchange (exchange theory) Reciprocity law
Exposure time = density *In other words, is the amount of exposure that reaches the film in terms of setting the aperture (intensity) and shutter speed (time).
Shutter ShutterAutomated tool used to expose film to light for a period of time minutes, and there are two major Muaan Gualq:1 - shutter between the lens elements (sometimes called the shutter plywood or laminated)2 - shutter focal level.Valgalq between elements of a compound lens in the lens barrel, close to the veil, and has a thin metal blades.The focal plane shutter is a compound in the body of either camera focal plane, and has a veil or a curtain of cloth or metal moving through the area of fiction vertically or horizontally when the image is taken.
Priority to the shutter Shutter priorityWay to in camera, the photographer choose the shutter speed manually, and the aperture is adjusted by the appropriate camera automatically, according to data given by the measurement system in the camera.
Shutter speed Shutter speedIs the effectiveness of the shutter that controls the duration of exposure, when the shutter quickly becomes shorter exposure.Positions and shutter speed to break the subject of a second you find a blog on the disk shutter speed.
Camera single-lens reflex Single lens reflex (SLR) cameraCamera is allow the user to watch fiction film formed at the level of accuracy by the lens by the mirror between the lens and articulated the film.
Trinity Law Rule of ThirdStyle in the composition is in accordance with the main interesting point in the scene, and be subject in one third of one of the parties is, the law of triangulation is used when the subject is in one third of the mid-point, almost two-thirds in the remaining two edges nearby.
Specific consideration \ Vision View finderWay to view this topic, a window or a screen or window in the structure of camera allows the photographer to see the field of view lens and the spaces of which will show the picture, there are different kinds of it, including under direct vision - visual framework - screen glass Almsnfr and the reflecting mirror.
Wide-angle lens Wide angle lensThen the lens focal length less than the diameter structure of the film which are used for it, so the angle of vision and wide, that is, the less the focal length of the lens and expanded viewing angle.
Variable focal length lens Zoom lens
Lens by which to change the focal length into several stages, you can switch to change the location of the focal length animated elements inside the lens and unimpaired focus and focal length number while changing the focal length to it.

TELEPHOTO:
Type of zoom lenses that are great for the image more than the normal standard lenses because the focal length and has a large area of the field is to be narrow and less than normal lenses.
