Understanding digital cameras, and how it works

Understanding digital camera


Digital Camera is a camera that can work without using film. We can easilycapture an object without having to bother took aim through the window of view because most digital cameras do not have it. Instead, digital camerasuse an LCD screen mounted on the back of the camera. The width of the LCD screen on any digital camera is different.

For storage media, digital cameras use the internal memory or externalmemory. Which often use a memory card, with a variety of sizes.

At the moment we press the shutter button, then in the camera happensstages to process the images. Although only a fleeting feeling, but stagesare performed in the digital camera long enough. Only, the process is done very quickly.


Here is a description of the process :

The way digital cameras work

1. The lens captures the image, then forwarded to the panel of the image capture. Catcher or so-called image sensors CCD-which also serves as a view finder, send images to the LCD. While on a DSLR camera, the image is also passed to the reflection mirror that reflects images to window peep (eye finder).
2. The images captured by the lens, passed on the color filter which will then be captured by the CCD or image sensor. The distance between the lens and the sensor is known as the focal length. This distance will also be a factor in the lens.
3. CCD task is to transform the analog signal (image captured by the lens) into electrical signals. In CCD sensors there are millions of dots known as pixels. So in terms of pixels or megapixels digital cameras actually refer to the number of dots on this sensor. The smaller the sensor and the more points the sensor, it will be more refined and higher resolution images produced.
4. The images captured by the CCD sensor forwarded to the image processing task processes all the data from the CCD sensor into digital data in the form of image file formats, and perform the compression process according to the selected image format (RAW, JPEG, etc.). In this section other than the chipset that acts, software (firmware) from the camera in question also determines the final image. The second part is what will determine the character of the digital camera. That is why, every camera they have the software and its own chipsets on their cameras.
5. The last process is to send the image files in the selected format to the storage (storage) or memory card. Typically, a SD memory card, CF and so on.
6. The next stage would go round the process is done outside the camera. But in modern digital cameras, still provides an option called PictBridge direct printing, ExifPrint and so on.

Additional Features

Digital Camera function in the form of an additional feature on the software level is more often encountered, for example, the addition of photo frames, photo effects such as sepia, black and white, etc.. Although these effects as an additional character only, but sometimes very helpful to reduce the image at the time of printing.
Some additional features are very useful is the backlight, which is photographing objects back to the light, white balance, face recognition to shoot models as well as anti-wobble on every camera has different terms such as anti-shake, Mega OIS, VR (Vibration Reduction), Super steady shot, and so on.
Some consumer grade camera even comes with a program that automatically organize photo shoots for special events such as fireworks, night shooting, outdoor, indoor, and sports.
In addition to understanding the composition and photography techniques, master the most important part of portraiture. For a photographer, they are loyal to one particular bit much due to the mastery of the camera is concerned, besides the character of the camera which also determines.
So, if you want to find the best camera, then in fact you are looking for a camera that matches your character and habits. So believe in yourself, because the end result anyway you also decisive.
