Characteristics of Resolutions

In the table that follows, we have the approximate characteristics of resolutions depending on the amount of megapixels of the camera. You must bear in mind that if you want to print on one larger size to the specified, the image will lose quality and be pixelara i.e., to print the image you notice points that comprise them, since they will be too big for that size. Camera lens after resolution, the most important factor to consider is the lens. To take good pictures, the camera must have optical quality (glass, not plastic). As the cameras less expensive 35 mm, some digital cameras bring fixed (without zoom) lenses, i.e., the lens always remains in the same position and with the same angle of view.

The only way that here we have change the frame for a photo, is closer or away from the subject or reason to photograph. For example: not always can we approach everything we want our subject; and when we are, most of the fixed lenses act as a large angular, which means a short distance will produce a noticeable distortion in the picture (their noses are more large, eyes are separated, and the faces) They seem as if they were bent toward the camera). With zoom lenses, on the other hand, let us closer without major problems the subject being photographed without having to invade your personal space and eliminating the distortion mentioned more above. We can also change the frame of the picture without moving us from the place, closer or away with the zoom from a viewing angle of a wide-angle lens to a telephoto lens (and any intermediate point). Also another advantage is that the zoom, tends to bring distant objects. Commonly, the zoom lenses are characterized by the degree of rapprochement that produce, which is nothing more than the difference between the wider viewing angle and the minimum.
