What Does digital camera Mean
The notion of camera can be used in various contexts. Today we will stay with its meaning as the machine used to take photographs. Digital , for its part, can refer to the system that works as information through discrete signals, such as letters or numbers.
A digital camera is a photo camera that uses an electronic sensor to digitize the images and store them in a memory . This differentiates these cameras from analog cameras.
The first cameras used a physicochemical process to record images. They were recorded on a roll or reel that then had to undergo an action known as developing , which allowed the photos to be captured on paper.
Digital cameras, on the other hand, store photos as digital data in a memory . The user has the possibility to store the images in the same camera or to save them in different digital equipment: a computer (computer), a USB memory, etc. Anyway, it is possible to print the photos to have them on paper.
In general, digital cameras allow recording not only photos, but also videos and sounds . The quality of the generated documents is usually measured according to the number of pixels, although there are other factors that must be taken into account (such as the sensitivity and the size of the sensor).
In addition to all the above, we have to point out that if in recent years the digital camera has become the favorite of many users, it is because it brings with it a remarkable series of advantages such as these:
-It has a large storage capacity, so Hundreds of photos can be saved.
-It supposes a saving in that it does not require to be buying reels frequently to be able to take snapshots.
-When printing one or more images that are stored in the camera, it is much easier than doing it with a traditional camera. And it is that they can be carried on a pendrive to the photographic store or they can even be printed at home from the printer.
-It has a series of really interesting features such as eliminating the photos that have not turned out well or that you no longer want to have, seeing the photographs that have been taken on the screen and even some models include small editors. These allow you to retouch them to a certain extent, set the date and time they were taken, cut them ...
-In the same way, the digital camera includes useful systems such as automatic shooting, burst ...
Despite the long list of advantages of digital cameras, it should not be overlooked that they also have their downsides. Thus, we can highlight the fact that they soon become obsolete because technology advances very quickly or that they have a higher price than "traditional" ones.
Digital cameras include the webcam , a device specially designed to work connected to a computer and conduct videoconferences or live broadcasts via the Internet.
