Captured In An Image

In addition to black and white time haze, as it crosses the street in the Washington State Capitol, a small boy wearing an ordered blue jacket and plaid shorts pays homage to his father's coffin I will. This image restores the hearts of countless civilians who are upset by the sudden death of the leader.

The images captured by military photographers, from dust and dirt in theaters to shining parade uniforms show the reality of life for British soldiers and women. People who captured these images are primarily military than anything else, and the second is a photographer, deploying them with rifles and cameras, taking the same risks as others, and developing their own unique reality of conflict Give close-up view to the public. Apart from action, they captured the daily reality of military life. Whether it's shooting the royal family or flying over thousands of feet in Afghanistan, you can see things as a Royal Air Force photographer. I shot some amazing things in my time, and I still think that it is the best work of the UK Air Force. It is difficult to choose only 5 photos, but I hope that my choice reflects my diversity as a RAF photographer.

The first thing we need to explain is the image capture mechanism. The most classic way to take pictures is to use the camera and film. However, this technique is not very useful in the field of digital image processing. This is because the captured image can not be easily processed by the computer. On the other hand, electronic acquisition is of particular interest, since the image can be digitized and then processed by a computer. Therefore, conventional electronic cameras are widely used. The electronic camera scans the image and generates an electric signal as an output. There are various camera technologies (Orthicon, Vidicon, CCD etc). Electrical signals generated by the camera are sent to the frame grabber. In the digitizing process, an analog signal is converted into a digital signal by using an A / D converter. Therefore, the image is converted to a matrix of 256 × 256 or 512 × 512 dots (dots). Brightness of 256 steps
