Cliffs of Moher, IrelandThe craggy Cliffs of Moher wrap around the western coast of County Clare, providing a stunning view of the Atlantic Ocean. The rocky cliffs reach 702 feet (214) meters at their highest point and stretch nearly five miles (eight kilometers) across. Photo Tip: When your subject is of indeterminate size—a mountain, a body of water, a snowscape—add a sense of scale by including something of known size, such as a person, a car, a tree, or an animal. This helps viewers understand what they’re looking at. Get more photo tips » See more photos of Ireland » Buy the Ultimate Field Guide to Travel Photography »
