Digital cameras – Take many photos today

Photos and more photos! You can find plenty of images everywhere. What are you waiting to get your own digital cameras? The social network and the online album is awaiting you.  You can take pictures at any time, from anywhere. The photograph is by far one of the activities that best adapted to the information revolution. From the pocket camera to new professional SLR-type equipment capable of recording high-definition video, users fully embraced the possibility of capturing a moment, without worrying about the rolls or have no doubt that the picture revealed is dark or out of focus.

According to experts, the people before he took a photo roll and half a year average, while it now takes about 600 digital photos in the same period. Everything is recorded. And share: last May, had 3.5 billion Flickr photos on your site, and Facebook, about 15,000 million stockpiled for its 200 million users (now has over 250 million). This is why you should choose from the best digital cameras!

In our country there is a wide range of equipment, designed for different budgets and interests. The range of options sometimes can get complicated by the choice of a model, so it is convenient to consider some elements to decide what to buy.

One of the hallmarks of digital cameras is the resolution of images captured, measured in megapixels, ie how many millions of colored dots (pixels) shall consist of the photo. Although in theory a larger number should be a better picture, in practice this is not necessarily so.

The best digital camerasproduces quality digital images using a sensor that picks up ambient light and translates these electrical signals in pixels, has millions of sensitive points on its surface, and each part of the photo records. But to produce a single image with higher resolution the manufacturers do not increase the size of the sensor, what they do is reduce the size of that sensitive spot (also known as pixel or element). This brings a lower sensitivity to light each of them, and the appearance of noise in photos: points in a different color than it should be, especially in dark areas.

So a 10-megapixel camera will not necessarily be two times better than a 5-megapixel, and with 3 or 4 megapixels is enough to print a photo with excellent quality. However, c digital cameras manufacturers have implemented techniques to correct these errors, and to stop selling new computers with few megapixel sensors.
