A picture may be blurred due to one of three causes:

a) blur due to depth of field

Gate access. University building (Albacete)

In such cases the blur is selective. That is, a part of the picture appears in focus-that which is within the limits of the depth of field, and the rest appear blurred. The photographer selects the subject and isolates it from the environment. In the picture above we have used the Nikon 50mm. f1.4 due to its large maximum aperture allows you to isolate a small portion of the rest of the scene. The limits of the depth of field is achieved with a judicious use of three different parameters:
focal length, focus distance and aperture. The use of selective blurring is an extremely important tool in the process of realization of the creativity of the photographer.

b) due to motion blur (camera shake) camera.

Cyclists. Ayna (Albacete)

is usually an error when capturing a photo. The most common is the desire of the photographer is to stabilize the camera up to prevent this from happening. But sometimes that can be used as a creative resource. In fact, for several years, the presentations were full of photographs intentionally moved, because this way you can get some aspect of abstract painting. But if you abuse this possibility, just by tiring. The vast majority of the pictures I have obtained in these circumstances I have seen pictures failed, but in some cases very specific, as the head of this paragraph, maybe I could appreciate a certain aesthetic value.

c) blur due to subject movement.

Luis Camoes Square. Lisbon (Portugal)

Here things are clearer. If the main subject of a photograph is blurred due to its own motion, making has become faulty. However, it is important to understand that other parts of the scene can be blurred without compromising the validity of the photograph. A fairly common example can be seen that this situation is that which corresponds to the picture above this paragraph. Here the subject is the same town and it has been necessary to use a tripod and long shutter speed, due to the limited light available. In these circumstances, people will blur if you have had some kind of movement. But the main subject is not them, but the square itself. And therefore, does not mean its unfocused decision was flawed.
