Digital photography terms

The most important digital photography terms, which is the entrance to anyone who seeks to enter the world of photography of the wider doors.

This topic may be boring being treated the theoretical aspect of digital photography, but in fact is essential and very important for both the novice in this area, so you can not go all the way in this direction without a password or a quick look at these terms and nomenclature. On the other hand, may be familiar to some of them, or you've heard a particular term, but you, in fact, I'm not sure of the real or his role in photography means, so we invite you to read these lines to the end in order to allow you to go out benefit and to identify clearly and accurately on each term of digital photography terms.


Pixel
Acronym for the word Picture element, a group of colorful finer points deployed regularly called all three points in pixels which give us the size of the image as well as its accuracy, the more the greater the number of pixels as the image quality better and clearer. The smallest part of the picture components that can be controlled on a computer screen. The pixel is used to express a unit of measurement of digital image through the length and breadth in density raster reflect the quality of the image.
Megapixel

Complications from a unit of measurement pixel image, as the value of one-megapixel equivalent to one million pixels, which means that sensor or digital camera sensor that can pick up a million pixels, or a million points of data. The image of dimensions 640 × 480 are from the category of 0.3-megapixel image dimensions of 1600 × 1200 pixels be the level of 1.9 megapixels, is multiplied by the length of the image in the display to get the result, of course always using pixels as a measuring unit.

RESOLUTION Expresses the amount of detail that can be exposed us to a particular image. Also called raster density of the image sensor, a discrete number of pixels that can be picked up by a digital camera sensor or sensor. The higher this number only if you can get a larger image. In other words, the image that will be displayed in 2048 and 1536 belong accuracy is 3.1 megapixels (multiplying the number of columns image Bmsfofatha) 2048 * 1536 = 3145728 pixels.

EFFECTIVE PIXELS
Number of real pixels recorded by the sensor or camera sensor after taking the picture, and this figure differs from the existing pixels in the slide number of pixels recorded is less than the real in the slide because some of them are covered in black or outside of the lens scale in order to work the white balance in the picture when recorded on media storage.

Memory card
The memory card can be considered among the most popular storage media that are used to store images captured by a digital camera (some digital cameras have their own) internal memory. The most prevalent types of memory cards, Compact Flash cards, Smart Media cards, Secure Digital cards, SD card and Memory Stick. In recent years, we knew these cards a remarkable development, especially with respect to absorptive capacity, which can be up to 2TB terabytes any million MB, and the speed factor is required in photography so the world's keenness number of memory card manufacturers in improving this aspect, so we find cards up speed read and write data to 280 MB per second, but this is an expensive kind.

SLR Single-Lens Reflex
This type of camera called shortcut Digital SLR which is a single lens digital camera reflective. What distinguishes this camera for the compact digital camera which is provided on a completely different view system, it depends mainly on the mirror, prism, and the eyepiece to preview the scene before taking a picture, and so instead of watching it on the screen.

Photographic lens
It is a single lens or a combination of optical lenses that are added to the camera in order to capture images. The photographic lens is built in two forms, either directly or with the camera lens can be changed individually, as is the case for Rifles cameras that allow the user to change the lens. The lens is characterized by two factors important determine the quality and value,They:-

Focal length
Which expresses the distance between the optical center of the camera lens, which is measured in millimeters mm sensor.

Lens speed
It is the property that determines which of the photographer the widest possible aperture lens, the thing that helps him to choose higher shutter speeds are possible and thus influence the depth of field can be either shallow or clear.

LCD viewfinder
It is a small electronic screen to be installed in the backend digital camera or a camera, and manage all of Tltqth lens and reflected through a mirror. This screen is usually used to see the scene in which the photographer wants to film, as well as watch and preview images after taking them, in addition to displaying the video clips recorded by the camera. Do not use this screen that makes a statement only in necessary cases, the fact that it contributes to the rapid consumption of digital camera battery. The photographer can inspect the scene and frame the image through the visual perspective.

Photographic Filters
An extension installed in front of the lens for a camera Rifles or compact, in order to change the way light entering it, the latter who is Baltqath sensor in certain circumstances. It can be likened to this matter, a person sunglasses that you change the degree of unity the light that enters the eye wears off. Candidate in the form of glass pieces. the most famous UV filters, the Skylight and Polarizer.

ISO
It is an acronym for International Standards Organisation any International Organization for Standardization and symbolizes the extent of the sensitivity of the film, which is used to determine the sensitivity of the slide in digital cameras, or so-called camera sensor. Photography in dim light needs to a larger number of ISO and vice versa, it is always advisable not to raise the degree of ISO because it affects the images via the emergence of noise. It also affects the quality of the videos as well, the larger the proportion of high natural light in a better place to work.

Aperture
A circular curtain in the lens is composed of several pieces in the form of moving blades control the diameter of the circle which is acting as the iris of the eye in humans, the larger the larger the aperture was light entering through the lens more, and vice versa, and symbolizes the aperture to F-number and whenever this However, a small number were aperture wider and allowed greater than the amount of light and vice versa means that Al-Qaeda counterproductive. Often expresses aperture symbol or F / f followed by the number, such as f / 22, f / 8, f / 16.

Shutter Speed
The shutter is the element that is controlling the duration of the light reaches the sensor of the camera. It consists of Starin, the first to open and the second to close it, through the movement of these curtains, there is a vacuum between them, which allows light to pass through. Depending on the speed at which it is moving the curtains control entry of greater or less than the light sensor on the ratio.

White balance
White balance (WB) all public settings by the photographer to adjust the color intensity in a certain image is done either automatically, where the camera selects the proper image set up by programming data developed by the manufacturer or by hand, where is controlled by the photographer freely. This setting is designed to display colors properly, especially Kalamata neutral and white colors.

EXIF file
This file contains all the information and data that the digital camera or smartphone camera having produced. So that we know the smallest details of the date and time of file creation, geographic location where she met the picture, a digital camera that was used in the imaging process and serial numbered type in addition to the rest of the other settings, such as, the amount of aperture, shutter speed, and ISO.

Histogram
Also called the image histogram The histogram of the image, which reflects the distribution of the color value in the digital photo as well as the brightness of the lighting brightness and darkness darkness so that if the deviation graph tilted to the left, this reflects the fact that the picture is dark or poorly lit and vice versa. Most modern digital cameras are available upon this integrated property where, where the photographer can inspect the graph for each image captured by the camera directly across the screen without having to wait for Maine on the computer screen through customized to modify and image editing software.

Dynamic range
This term I have known photographers term high dynamic range HDR, it means the difference between winning proportions of dark and light areas related to lighting in a particular image. In the case of the field images or high-dynamic range, we are talking here about the consistency of perfect balance between strength ratios brightness lighting and dark areas at the same time.

The camera sensor
The sensor through his name indicates that he is sensitive in all digital cameras without exception, it is the latter which is located by the light drawing a picture you see the camera. The sensor for digital cameras is a product was, which was used in the classic cameras or the so-called old analog imaging machines, in 1975, that the invention of the first digital camera has been before by American engineer Steven Sasson Steven Sasson.

Digital zoom and Optical zoom
Zoom in general, his role is to bring and enlarge aimed at clarifying the features and small details. In order to achieve this goal is the use of either the optical Ballroom call it a mechanical zoom name too, because it is on the lens level does not affect the quality and clarity of the image on the reverse digital zoom, which causes distortion of the image as the person to raise its value more, a good example for understanding the idea more, open a specific image on your computer and you will notice Petkberha they deform and lose their quality whenever you greater Petkberha. This is exactly what happens with all the pictures in which they are relying on digital zoom, such as it is the case when using the zoom smartphone camera.

This was a comprehensive look at some of the most heavily traded between persons wishing digital photography terms to enter this world and see the secrets.
