In reality, there are really twelve million pixel images, and it is fantastic plans of six megapixels.

And of course, more megapixels means you can buy larger, more expensive memory cards for the hint!

Megapixels are something to remember that in a few cases:

a) if you want giant prints (20 by 30 inches, posters, etc.)

b) if you want the culture of a large part of a photo to isolate the issue, with enough pixels for prints in a reasonable size. But if you do not change your plans and no longer needed A4, there is no need megapixal crazy. Six megapixels do the work very well. It is interesting to note that large files much time to download, for the photos exclusively for viewing on your computer (on the Internet, e-mail, presentations) – require only a few pixels. So before you rush to buy the latest, who sings and dances “digital camera, take a moment or two, and get really what you need.

Most mid-price digital cameras have an integrated 3x/4x. These figures refer to the optical and digital zoom. Most cameras have bothoptical and digital zoom, with the exception of a small number ofpeople with low price, the tendency to blur images and pale. A digitalcamera the zoom function is very similar to a camera and does the same,namely the object closer. Anyway, in the cameras of two types of zoom,optical and digital. Optical zoom is the zoom the camera away.

The digital zoom, and zoom through the simulated explosion of aselected part of the picture. It is not to be confused with the editingof photos, based on the applications, after the image is produced.Another misconception of this type of zoom, it is particularly usefulto take photos from afar. That can not be further from the truth.Optical zoom is far more important in a digital camera and should serve as a criterion for the comparison of different models rather than adigital zoom, or a whole.

Everything else he can to the fact that thecamera has two types of zoom functions, digital and optical.Traditionally, such the cameras are 35 mm or APS only the optical zoom.Integrated optical zoom lens with an image closer to the photographer.

The energy of thedigital zoom and resolution are two different things without anyconnection with any of the other. The resolution expresses the numberof pixels in the image, while the optical zoom refers to the power ofthe lens. It has nothing to do with the solution and not to increase ordecrease. Another trend is off the digital zoom the camera. Manyphotographers do not rely on this feature, not the culture and the sizeof the photos themselves on the computer. It is not a very good, because it reduces the efficiency of the camera
