Under development for digital cameras we do not Nkhaloa them and sometimes acquire these machines randomly somewhat without a study of the needs of the photographer or the features found out For an expected result from picking up a certain image must be camera preset terms of potential for this snapshot therefore diversity produce these Machines commensurate with the need of the photographer. In this article we will review digital imaging and machine types.
Digital cameras What does this mean?
In fact when we call camera it digital, it applies if one of the cameras that rely on a memory card storing images in the form of numbers the system binary (zeros and individual) and using the means of showing digital data to view images stored and most important: screens and printers.
And digital cameras of all kinds are dropping the captured image on an electronic chip called the sensor (Sensor), which here acting as a film in cameras Filmah.
And digital cameras are divided into three basic types will review the advantages and disadvantages.
The first type: compact digital cameras | Compact Cameras
The smaller types of digital cameras and most prevalent among users of others professionals so that you can put it in your pocket (pocket camera) and fall these cameras under another name, a Point and Shoot abbreviated b (P & S) and this label back to nature photography these machines because they requiring only that aim at the target and imagined.
Features:
1. Appropriate size and weight.
2. Ease of Use.
3. Price is reasonable for the results of the imaging preset automatic.
Cons:
1. Control settings is limited.
2. Can not replace the lens they are considered part of the imaging Aloat.
3. Sensor chip (Sensor) is smaller than in other types of imaging machines, which may cause confusion in the photos when shooting in insufficient lighting.
4. Unavailability considering slot (Viewfinder) sometimes use the display which makes image capture in direct sunlight somewhat difficult process.
But in spite of these shortcomings, it is considered good quality footage family that does not need to factor Technical mostly with other privileges began posed competitors in this field, such as cameras simple nanomedical (Ultra Compact), carrying with advantages and disadvantages but they are smaller in size than usual. The cameras Advanced Compact and developed in which the control is manually and focal bringing $ 3X to 7X.
Type II: the camera Bridge - Bridge or SLR-like Cameras
The link between compact cameras and professional, therefore, called bridge Bridge machines which contain features of both types fixed Fdsthe and similar in shape to professional cameras, a full manual control and after focal $ 7X to 18X.
A DSLR cameras used by professional photographers usually are companies Nikon and Canon known manufacturers of this type of camera.
DSLR | contains a mirror that reflects what passes through the lens of a specific look that allows the photographer to see the target precision, color and brightness and framing are recorded and taken in the form of the captured image data.
This type allows the use of several lenses including commensurate with the need of the photographer and the size of the sensor (Sensor) more content in the type I and II which reduces noise when shooting in dim lighting.
Not only that .. .
With the continuous development in the production of digital cameras, each type falls below a lot of different cameras in features, and this important commercial competition and serve photographers and all they have to do is choose the camera commensurate with Aanaajthm and orientation.
Features:
1. Selection of appropriate lenses according to the needs of the photographer.
2. The presence of specific consideration Viewfinder.
3. This type accurately focus on the goal.
4. Speed of response.
5. Image quality compared to the other types.
Disadvantages:
● Size and weight is relatively large, which may not suit some amateur photographers.
● use of this type needs to learn some pre-imaging settings.
● some lenses prices for some types of imaging may be high
