A lot of people have digital cameras. An awful lot of foreign terms in a digital camera, such as megapixels, ISO, LCD, HDMI, SD, and other terms that are confusing. Let's try to learn these terms so as not to choose the wrong digital camera.

16:9 ratio


Size comparison photo with 16:9 dimensions for length and width. This size is suitable for display on the screen wide screen. For example want to be shown on television or the big screen HDTV.

4:3 ratio


Measure the dimensions of the photo or video is the most common especially if you want to be printed or you want to be shown on television on non wide screen tube television, for example.

AF-Lock


AF stands for Auto Focus. AF-Lock used to lock the Auto Focus function.

Here's how by pressing the shutter button to focus half of the image is locked.

This function is very useful, if you want to focus on the object that You want to put on the side. How focus on first the object while in the Middle, and then slide the camera while pressing the shutter button half.

Aperture


The aperture is the camera lens aperture magnitude to determine how much light can enter and concerning the image sensor in the camera.

On a pocket camera aperture usually it is set automatically by the camera system. Whereas a more sophisticated camera, can be set to manual or automatic.

Aspect Ratio


Size comparison of a photo or video. The most common are 4:3 and 16:9 (wide screen).

Autofocus (AF)


Autofocus or often abbreviated AF digital camera is the ability to automatically create an object of the desired image be more sharp or clear.

For digital camera novices, usually this function is automatically activated. But for sophisticated digital cameras, you can redirect the focus manually by adjusting the lens.

Automatic exposure (AE)


Automatic exposure (AE) is the digital camera's ability to set the aperture of the lens (see aperture) and shutter speed based on the surrounding light conditions.

Digital cameras for beginners such as pocket camera has had 3 or more different AE mode.

Burst Mode


Burst mode is a feature of a digital camera to take some pictures at once in the waktusingkat. For example, you want to take at once 10 photos in 3 seconds.

Burst mode is especially useful when you want to take a picture of an object moving rapidly.

The other term is the continuous shooting mode.

CCD


CCD (Charge Coupled Device), is a chip in the camera that functions as the image sensor.

CCD consists of millions of capacitors. Does it do that is when light enters into the camera through the lens, then the light will reach parts of the CCD.

The technology is currently more popular IE CMOS.

Cmos Sensor


CMOS (complementary metal-oxide semiconductor) is the image sensor in a digital camera consists of an integrated circuit to record an image.

CMOS sensor comprising a pixel including a photodetector.

When the light gets into the camera, every photodetector will make electric current based on the intensity of the light that hits it.

Digital cameras will change the data from CMOS into pixels that eventually became a photo.

CMOS CCD replacement because it became faster and more efficient use of the battery.

Compactflash (CF)


CompactFlash (CF) is one of the types of memory cards used in digital cameras.

The function of the memory card to save photos and video data that you have created.
