Great photography starts with sound composition. Know your subject, the exact focal point, and how to position it within the frame to accentuate the element you viewer sees first. 

Learn and practice the “Rule of Thirds,” a photography principle that places the primary focal point of any composition at the intersection of vertical and horizontal lines dividing the frame into equal thirds. The primary element should be positioned either along one of the lines or at their intersection. Most modern cameras have a thirds grid that can be turned on in the viewfinder to aid composition. 

Tack sharp photos are the mark of a skilled photographer. 

Modern cameras are so advanced that solid focus is all but guaranteed in auto modes. Nonetheless, study the focal controls in all modes for maximum sharpness. When natural conditions like low light, moving subjects, and multiple focal points try to confuse the camera’s auto-focus, you’ll need to understand how to compensate.
