In sports photography, focusing is a difficult to master the techniques, this is because the sports photography of the absorbed object has a very strong movement, is very fast, it is unlikely to allow you to slowly to wonder, better focus. Professional sports photographers were taken to track focus: changing the focal length, let competitors at any Canon CG-580 Battery Charger  time maintain a clear image in the viewfinder. However, it skills beginner photographers are hard to practice using perfect.

  Easier way is through the camera’s AF system. Although the auto focus system can quickly focus on good, but if you use the wrong method, could not perform it’s utility. In other words, only the camera body is just enough to remain on the scene in the location box in the center of the window in order to achieve the purpose of accurate focusing. If the camera is equipped with the lens focal length is not very long, larger perspective, camera body movement is placed in the center of the viewfinder in the location box, fairly easy; if the camera the lens is equipped with more than 200 mm telephoto lens, due to the smaller the angle, it is necessary to track the absorbed, but also at the location box, may be very difficult. To accommodate this situation, may wish to change these habits can be temporarily regardless of how the viewfinder scope, only use location box tracking is taken, this feeling may be relaxed. If players shot was taken in locations outside of the center of the screen, but also to take advantage of automatic location system, should focus automatically lock device, fixed focus. If was taken is of fierce mobile time not allowed use of JVC GR-AX800 Battery Charger  locking device, and composition is not required to be taken in a location other than the center of the screen is not available, at this point it must be lifted automatically focus to manual focus.

   Making a sports photo there is also a common method of focusing, that’s the trap focus, that is, when absorbed into the intended focus, then press the shutter of the camera. Some advanced cameras, have this kind of performance. Trap focus is applied to sports photography, such as action to shoot jumpers flew over the bar by this method is ideal. When shooting, you can put a point focus adjustment in athletes might cross the rails and focus lock, move back and forth so that it no longer, and   depending on the player when flying over the cross bar press the shutter, you can take to the high clarity of photos.

  Worth saying is, if a photo taken at a rapid speed of movement, such as race, when we were using trap focus skills, must also be pressing the shutter in advance. That is the main body arrived at the venue before the moment of pressing the shutter. Shutter in advance, you can make up for the shutter to that period of time between shutter actually opens. Of course, currently has some advanced auto-focus cameras focus ability catch the racing speed, even if the car is at maximum speed from the transverse Gallop past on the screen, it can still be shot down. If you not clear before the shooting moving objects through which a little, but only through an area, then you can use area focus mode, high speed film for shooting as much as possible, depending on the lighting conditions and film speed, try to use a small aperture. When the focus, according to the lens on the depth of field table, within the scope of  Panasonic Lumix DMC-FZ20 Battery Charger this zone is in depth, focus on the exact one-third offices in the region close to the camera, because the prospect of deep less than deep background. Do this, you can get good results. If players appear in the far distance, can be hyper-focal length shot. From depth of field can be found in the table on the lens and aperture for shooting the depth range, and then turning the adjustable focus band, deep background signs at the adjustable focus band of infinity signs, which will make you get the most out of the aperture used in depth of field. If was taken far athletes will appear regularly in several different areas, available paper tape to make a circle, installed at a distance of over, it is best to use white paper, set above a few special regional tag, follow mark focusing before taking pictures, you can very quickly determine the focus position, does not work through the viewfinder focus.

   Focus is of course in order to pursue the purpose of high quality images of, clear focus are the basic requirements. For beginners, however, require that each photo can focus clearly has a certain degree of difficulty, because the factors influencing the focus clearly there are many, if not properly grasped, it is difficult to obtain clear images. Here are a few good way to maintain a clear focus, for the beginner’s reference:

  1. To prevent shock. Vibration makes image shake blur in photos, even if the original focus very accurate images, would affect the definition of knot like. Vibration of generally have two reasons:

  First, camera shake, that is, when the shutter is pressed, camera because of controlled instability caused by shaking.

  Second, main move, that is, at the moment of lens shutter opening, be taken subject is in motion, and the shutter speed is not high enough, no solidification dynamics, so image appear fuzzy.

  To avoid camera shake, can then take action in three areas: ① place the camera on a tripod, steady camera. If limited by shooting conditions, unable to support a tripod, you can use a monopod. ② increased shutter speed (usually a 1/250 second shutter speed), will be able to reduce camera vibration generated image shaking. ③ adopt the correct machine. In the case of no tripod, machine posture of right or wrong, will directly affect the stability of the camera. Dynamic fuzzy was taken subject to overcome, only one, that is, increase the shutter speed, as long as conditions permit, shutter speed, the faster the better.

  2. Not one-sided pursuit of small aperture. Beginners think small aperture will increase the depth, will certainly make the image clearer, so they often do not point, received the aperture is small, especially when the focus is not sure, more believe small aperture can help them help. But the end result is often not ideal, because a smaller aperture will result in reducing the shutter speed, and thus cause camera shake. Therefore, the one-sided pursuit of small aperture is not the best, the correct approach should be actively using a fast shutter speed and a tripod.

  Japan photographic little Hisayasu Shin Ji in focusing has its own unique way. When shooting at a time, he is back on three cameras, the focus of the camera is determined to be: from its own location 10 metres away, with a 100 mm zoom lens, the focal length of Nikon Coolpix S50 Battery Charger  100; a distance of 20 metres away, with a 200 mm zoom lens, focal length 200; a distance of 30 metres away, with a 300 mm zoom lens, focal length, 300. In his view, this shot without distraction to adjust the focal length, which can visually determine the result to the camera.
