English 188Photographing a moving subjectSituation: You would like to snap an action shot of a moving child or pet. Theautofocus is activated, but because the subject is moving, the image may beblurred. In particular, when the distance between the camera and the subjectis changing, it is difficult to lock the focus on the subject. Here are some hintsfor successfully capturing images of moving subjects.k Reasons for unfocussed imagesWhen the shutter release button is gently pressed halfway, the camera’sautofocus works by determining the distance between the camera and thesubject. Once the subject is in focus, if it then moves before the picture issnapped, the image may be out of focus. This often happens when you oncelock the focus on a subject and then wait for the right moment to snap thepicture. And, conversely, a blurred image may result if you press the shutterrelease button all the way in one step in an attempt to quickly capture anaction scene, thus failing to activate the autofocus in time.k Preventing blurred images (How to use the manual focus [page 78])In addition to the autofocus, a manual focus mode is also incorporated in yourcamera. In the autofocus mode, the distance between the camera and thesubject is automatically determined when you press the shutter releasebutton halfway. In contrast to this, with the manual focus mode, you manuallyset the focus by specifying the correct distance between the camera and thesubject before taking the picture.k How to photograph a moving subject1 Set the camera’s focus mode to the manual focus. Set the focus distanceto the correct distance between the camera and the subject.2 When the subject is at the set focus distance, gently press the shutterrelease button all the way down.i Images can be quickly captured without waiting for the autofocus toactivate.i Because you are presetting the focus distance, the focus can be moreaccurate.i When photographing a moving subject, press the shutter release buttonjust before the subject reaches the focus distance, and the shutter will bereleased when the subject is at the correct distance.i Use manual focus to avoid incorrectly focussed images when there is anobject between the camera and the subject you wish to focus on. |
