Auto and Manual Focus Modes in Digital Cameras
One of the important phases of shooting a good photo is focusing on the photo's objects. Photos that are out of focus look bad and blurry. Sometimes shooting out of focus objects is done on purpose as an artistic effect but in most cases a sharp focused object is the photographer goal.
Most low-end pocket digital cameras do all the focus work for you. These are literally "point and shoot" cameras. Furthermore even if you wanted to manually focus using such cameras it would have been practically impossible since they do not include a real optical viewfinder. Using the LCD to check for focus is useless as the LCD is not good enough to truly let you know if an object is perfectly focused or not.
Digital SLR cameras on the other hand have an optical viewfinder that allows you to truly see the photo through the camera's lens. With digital SLR cameras you can see how well the objects in the photo are focused and correct the focus as needed.
Digital cameras support at least three focus modes:
Like any other feature automatic and manual focus modes have their pros and cons. The first step to using them to your advantage is to understand how they work and what they were designed for. The next step is to experiment shoot photos using different focus modes and different types of objects and see how the camera behaves. Once you have done that you will be ready to instinctively use the best focus mode for each photo situation.
