Manual Focus

One of the important phases of shooting a good photo is focused on objects in the picture. The photos are out of focus blur and poor. Sometimes shooting out of focus objects is done on purpose as an artistic effect, but in most cases, an object is the goal focused Sharp photographer.

Most cameras low-end pocket digital do all the work focus for you. These are literally "point and shoot" cameras. Moreover, even if you wanted manually focus using the cameras mentioned, would have been virtually impossible, since not include a real optical viewfinder. Using the LCD to check focus is useless as the LCD is not good enough to really know whether an object is perfectly focused or not.

Digital SLR cameras have instead an optical viewfinder that lets actually see the picture through the camera lens. With digital SLR cameras can see how well the objects in the photo, the focus and correct as necessary.

Digital cameras supported by at least three focus modes:

Manual Focus: In this mode the camera not automatically the focus of the objects in the picture. You will have to manually set the focus as desired. This is achieved either by pressing a few buttons that in turn change the approach, or more commonly by the rotation of a lens focusing ring to the right or left as needed. You can see the results of changing the focus of looking through the viewfinder. When happy with the approach that you can press the shutter button to take the picture.

Single Auto Focus: In this mode the camera automatically focuses on the objects in the picture. The camera automatically focuses when you press the shutter button either all the way to shoot a photo or half down to lock the focus. In this mode the autofocus process is performed only once as soon as the shutter button. Once the target is get to hang and not changed until the next time you press the shutter. If you hold the shutter button halfway and the camera moves or the object moving the focus had been lost. This mode is useful when shooting static objects. In most cases you press the shutter button and keep it halfway down. The camera will run the autofocus process. It will let you know when focus is achieved by displaying a green icon and playing short beep.

Autofocus mode: In this mode the camera continuously focuses on the objects in the picture. Once the button shutter pressed and the time it takes place halfway through the camera continuously focuses on the objects in the picture. In this mode the camera continuously corrects the focus to the distance of objects from the camera changes. This mode is useful when you take pictures of moving objects, like a racing car during a race or airplanes during an airshow. You can keep the shutter button halfway and continuously move the camera to track the object. The camera will continuously keep the object in focus. When you are ready to take the picture just press the shutter button to the bottom.

Like any other characteristic modes of manual and auto focus, have their pros and cons. The first step to use to your advantage is to understand how they work and what they were designed. The next step is to experiment shoot photos using different focus modes and different types of objects and see how the camera performs.
