digital photographyIn the beginning of the digital photography development, the most difficult issue that the producers had to face was the reaction of the digital captors.

That is how the number of the millions of pixels, which could be realized with the captor, was considered to have the utmost importance.

In time, the producers have noticed that this categorization of the cameras depending on the number of mega pixels on the captor was very catchy for the general public especially because it was something very understandable.

Nowadays the large majority of the amateur cameras have “branded” in, with capital letters in very visible areas, the number of mega pixels, and this can become the most important marketing device for every new generation of cameras.

Still the mega pixels are not an absolute measure of the camera’s quality, nor of the quality of the images obtained with the same camera, because for the quality of the images are responsible a larger number of factors among which the dimension of the captor, the quality of the objective, the signal processing from the captor and not in the least the skill of the person taking the photo.

With the increase in the number of pixels don’t always come positive effects for the image quality, because the “crowd” of a great number of pixels on the same surface of the captor increases generally the “electronic noise” that can manifest rather unpleasantly under the form of some granulation especially in the shadow area or while using and increased sensitivity.

What the producers don’t seem to be in a hurry to tell us is, that not all the pixels are equal from the quality’s point of view, and that makes an image of 6 mega pixels resulted from a camera of professional class to be highly superior to the one of 8 mega pixels resulted from an amateur camera.

The major difference in this case is the dimension of the captor. The professional camera captor can be over 4 times bigger so the pixels would have a larger surface to catch the image and that will increase the image’s quality.

Let’s not forget that in the case of digital photography the best quality is resulted in the case of the pictures with fewer elements possible: portraits, objects and macro-photography.

The most difficult subject for the digital photography is the landscape containing a great number of elements, many of them far, like the forest leaves, the tree branches or the grass.
