Have you felt bad when there was a very important moment in your life and did not have any pictures? There are special moments in life that really needs a photograph or video coverage in order to commemorate it. Digital cameras or video cameras will best take care of that.
A digital camera also known as “”digicam”” is a camera that takes photograph and even video through digital recording. This is done through an electronic image sensor. It has become a trend in this 21st Century. One advancement it has compared to old cameras is that it could display the image taken in the LCD (Liquid Crytal Display) immediately. This could give the user the feedback about the quality of the shot. If it was bad then it could be deleted right away and take another shot. The images taken are automatically saved in memory cards that could be read by various devices like computers. From the computers the images can now be printed.
Most digicam can record videos including sounds as well as photographs. Others have built-in programs that can already perform picture editing such as cropping. A few have GPS receiver and can be use to tagged pictures in the internet.
This device utilizes the same principles as old and conventional film cameras. That is actually using a lens with different diaphragm to focus light and thus picking up images. The diaphragm and shutter adjusts the amount of light to have a clearer image recorded electronically. And for long and steady coverage, most digicam are attached to a tripod stand.
Digicams has wide ranges of resolution. Resolution is of how much detail a camera can capture also defined by this quantity called pixels. This is limited on the image sensor installed in the camera that turns light to signals resembling the images. These signals are then displayed in the LCD monitor.
Image capture in digicams can be single-shot or even multi-shot. In the former, the sensor is exposed to light once through the camera lens. On the other hand, the latter exposes the sensor to light in numerous times creating numerous image pick-up.
The image taken by digicams has adjustable angle views depending on the image sensor used and the focal length of the camera lens. This is how zooming made possible. You can zoom in or zoom out depending on the desire of the user. The zooming action can sometimes cause a poor quality images because of the distance of the image taken and the length in between lens and the sensor. That is why zooming requires adjustments on the aperture to get a high quality shot. Most digicam have automatic mode in zooming that enables even an amateur user to still get a quality shot.
