(All photos are of Gutenberg's Photos )

We saw, talking of the exposure time , as the variation of time in which our results different genres shutter remains open on our photos, especially when it comes to moving subjects.

Today I want to introduce a related concept: photographing moving subjects using the technique of panning .

Panning is a technique that is to follow with the camera on a moving subject while shooting, so you get a picture in which the main subject is sharp while the background is "moved" or blurry.

It seems clear that using the panning is very difficult to get perfect results because it requires that the camera moves smoothly with the movement of the subject. In addition, the panningi works best with objects that follow a straight path, and therefore never change perspective.

How do you put into practice the panning?

• Select a shutter speed slower than usual. Start with times of 1/30 of a second and stretch it as you shoot your tests. Depending on the lighting and the speed of your subject, you can achieve optimum performance at speeds of between 1/60 and 1/8 of a second, although in the second case greatly increase the possibility of having photo completely moves.
• Position yourself so you do not have the view blocked by anything or anyone. Consider also the background of the photo: even if it appears out of focus, the presence of numerous colors could create noise to the image. Try backgrounds that have few colors.
• Follow the subject as it moves. Only in this way you will get the effect of "panning". If you use very long goals is recommended to use a tripod, rather than rely on the steadiness of your hands.
• For best results make sure that your movement is parallel to that of the direction of the subject.
  
• If your camera has autofocus, you can leave the task to focus on the moving image, prementdo lightly on the shutter button
• And if your camera fails to focus quickly use the manual focus , Taking as reference point the point where you think that you will begin to take
• Started to follow the subject before pressing the shutter button, and stop briefly after rilsasciato. Will allow you to make a more natural motion during the exposure time.
