Earlier, I started this "Basics of Composition" series with an introduction to the importance of your subject.  In this edition, I'm going to explore the "rule of thirds" -- perhaps the best-known rule of photographic composition, as well as the Fibonacci spiral, which is widely considered to be a close relative.  If you didn't see the earlier article, this would be a great time to catch up before we move ahead.

IMG_7857_thirdsThe rule of thirds simply divides your photo in thirds both vertically and horizontally, creating four vertex points where these lines intersect.  By aligning elements of your photo on (or near) these lines, you create an imbalance in the photo that tends to be a little more interesting than a completely centered photo.  In the photo on the left, the V8 emblem is aligned with the left 1/3 line, and the right line lines up with the body panel.  Note that you can align with either the horizontal or vertical lines, and/or any of the vertex points (which are automatically on the lines).  If I were to re-shoot this same scene again today, I might even play with moving the emblem up a bit to align the horizontal body panel and the holes in the hood with the horizontal thirds lines, but you get the idea here.

A related tool has its roots in middle-aged math.  The Fibonacci Spiral or Golden Spiral is named for the Italian mathematician who might be best-known for the sequence of numbers where each number is the sum of the previous two (1, 1, 2, 3, 5, 8, 13, etc).  As thrilling as these numbers are, when you plot them in a grid and connect their corners with an arc, you wind up with a spiral that's been seen in all sorts of natural objects; thus the belief that this spiral might also be a useful tool in composing our photos.
