Using the grid overlay in your camera's viewfinder, you can position the most dynamic portion of your subject so that it falls into just one third of your photo. Play with landing points of interest in either the top or bottom third, or in the extreme left third or right third.
Easy Practice: ⅓ vs. ⅔ rule. Using the grid, divide your photo into thirds either vertically or horizontally. Now, intentionally position the subject of your photo so that it takes up just one third of the image's space.
Intermediate Practice: Exploring Rule of Third Intersections This time, you'll want to make special note of the four intersections that your nine lines create when they cross. Any one of these junction points is a great place to position a spot in your photo that you want the viewer's eye to be drawn to. Color, action, sharp lines, sun spots, curious blurs - anything that you find interesting can be lined up with one of the four intersections to bring some extra attention to your shot.
