How Digital Cameras Work

When we know the image in the camera, then during the shooting we can imagine and will take into account such as what the display or output of objects that will be left.

In camera

At the time we press SHUTTER button, the camera is going in stages to process the images. Although only feel only a glimpse, but the stages in the digital camera is quite long. However, the process was very fast. Here is a description of the process:


1.
Lens captures the image, then forwarded to the panel trap image. Catcher or normal image sensor called a CCD-also functions as a view-finder to send the image to the LCD. While the DSLR camera, the image also miss the reflection mirror to reflect the image window to intip (eye finder).
2.
Image by the lens, be missed on the color filter, which then will be arrested by the CCD or image sensor. The distance between the lens and the sensor is known with the term focal length. Distance is also a factor that will be the multiplier on the lens.
3.
CCD is the task of the analog signal (the image captured by the lens) into electrical signals. In the CCD this point there are millions of sensors, known as pixels. Term or so pixels in megapixel digital cameras actually refer to the number of dots on this sensor. The small sensor point and the more sensornya, the fine and the higher resolution image that is produced.
4.
Image captured by the CCD sensor forwarded to the processing of its duty to process the image data from all CCD sensor data into a digital image file format, compression, and the process according to the selected image format (RAW, JPEG, etc.). In this section in addition to a role of the chipset, software (firmware) from the camera that also determine the final image. Second part is what will determine the character of the digital camera. That is, they each have the camera software and its own chipset on their camera.
5.
The last process is to send the image files in the selected format to the storage (storage) or memory card. Typically, a memory card SD, CF, and so forth.
6.
Adlaah next stages of the process is done outside the camera. However, in the modern digital camera, still provides the option of printing directly called PictBridge, ExifPrint and so forth.

Thus the image on a digital camera. However, the stages are only basic or foundation of almost all digital cameras. In some brand digital cameras, usually still add a few processes to improve picture quality, including the addition of features on casement or application software.

Enhancements

Additional features include a function to the level of the software more often we see, for example, the addition of photo frames, photo effects like sephia, black and white etc.. Although these effects are only as extra, but it sometimes helps to reduce the image at the time of printing.

Some additional features that are very useful backlight, which is taking the distance the object light, white balance, introducing photography to face anti-oscillation model and the camera on each term has a different, such as anti-shake, Mega OIS, VR (Vibration Reduction), Super Steady shot, and so forth.

Some consumer-class cameras are even equipped with a program that automatically set the shooting for a special event such as fireworks, night shooting, outdoor, indoor, and sport.

In addition to understanding the composition and photography techniques, the device is the most important part of portraiture. For a photographer, they are loyal to one particular bit is because many of the control of the camera, other than the character of the camera also determine.

So, if you want to find the best camera, then you are actually looking for a camera to match your character and habits. So believe in yourself, because the end result yet you also specify that.
