How It Works Digital Cameras

By the time we pressed the shutter button, the camera happens in stages to process the image. Although only briefly felt, but the stage is done in the digital camera long enough. It's just that, the process is done very quickly. Here is a description of the process:

1. Lens to capture an image, and then forwarded to the panel catcher image. Catcher image or so-called CCD sensor, which also serves as a view finder, sending images to the LCD. While the DSLR camera, the image is also passed to the reflection mirror that reflects the image to the window peep (eye finder).

2. Images are captured by the lens, color filter is passed on to 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 an electrical signal. In this CCD sensors there are millions of points known as pixels. So the term pixels or megapixels on digital cameras actually refers to the number of points on this sensor. The smaller the sensor and the more points the sensor, the more refined and higher resolution images produced.

4. Images are captured by the CCD sensor forwarded to the image processing tasks to process all the data from the CCD sensor into digital data of image format files, and compression processing according to the selected image format (RAW, JPEG, etc.). In this section other than the role chipset, software (firmware) from the camera in question also determines the outcome of the picture. The second part is what will determine the character of the digital camera. That is why, each of their cameras have software and its own chipsets in 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 of the process adlaah done outside the camera. But in the modern digital cameras, still provides a direct printing option called PictBridge, ExifPrint and so on.

Thus the process of drawing on a digital camera. But these steps only basic or foundation of almost all digital cameras. In some brands of digital cameras, usually still add a few processes to improve picture quality, including the addition of features on casement or software applications.


Additional Features

Additional features of the function at the level of the software more often we meet, for example, the addition of frame images, effects such as the Sephia photos, black and white, etc.. Although these effects in addition to nature 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 light, white balance, face recognition for photography as well as anti-shake models that have cameras on each term as varied as anti-shake, MEGA OIS, VR (Vibration Reduction), Super steady shot, and so on.

Some consumer grade cameras are even equipped with a program that automatically adjusts shooting for special events like fireworks, shooting night, outdoor, indoor, and sports.

In addition to understanding the composition and photography techniques, mastering the device is the most important part of portraiture. For a photographer, they are loyal to one particular bit more due to the mastery of the camera in question, other than the character of the camera also determine.

So, if want to find the best camera, then you are actually looking for a camera that fits with your character and habits. So believe in yourself, because the end result you're decisive.

How Diesel Engines Work

Categorized diesel motor fuel in the motor piston and the combustion engine (internal combustion engine) (simplenya usually called "mobor burn" only). Diesel motor working principle is to transform chemical energy into mechanical energy. Chemical energy in reakasi get through the process of chemical (combustion) of fuel (diesel) and oksidiser (air) in the cylinder (the engine).

In the diesel motor fuel can consist of one or more depending on its use and in one cylinder can consist of one or two piston. In general, in one cylinder diesel motor has only one piston.

Working Principle.
The pressure of the gas and biofuel combustion air will push piston is connected to crankshaft using piston rod, so the piston can move back and forth (reciprocating). Alternating motion piston is converted into rotational motion by crank shaft (crank shaft). And vice versa crankshaft rotational motion is also converted into alternating motion of piston in the compression step.

Based on analyzing how the system works, diesel motors are divided into two, namely diesel motors that use airless injection system (solid injection) which was analyzed by dual cycle and diesel motors that use water injection system is analyzed with the diesel cycle (while motor gasoline was analyzed by otto cycle).

The difference between diesel and motor gasoline motor which is located on the actual process of fuel combustion, the combustion of gasoline motor fuel due to the fire jumps the electricity produced by the two-electrode spark plug (spark plug), while the diesel motor combustion occurs due to an increase in mixture temperature air and fuel due to the compression piston to achieve a flame temperature. Because the principle of the fuel ignition due to the pressure of diesel motors are also called compression ignition gasoline engine while the motor is called spark ignition engines.
