Next we have the golden rule. The golden rule, also known as the golden mean, is a more complex tool. Most professional photographers use it, but if you learn it, it will help you considerably. I think this is one of the hardest things to learn in photography. The golden ratio defines a spiral pattern that appears repeatedly in nature, from the shell of a nautilus to the sunflower to the spiral shape of the galaxy itself. This happens in more natural subjects than you can imagine, some places you can find it are simple things, like an ear or a snail. The golden mean is defined by a mathematical sequence of numbers known as the Fibonacci sequence. This is why the spiral is sometimes called a Fibonacci spiral. By definition, the first two Fibonacci numbers are 0 and 1, and each remaining number is the sum of the previous two. The sequence is therefore: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, which continues indefinitely. The ratio of each pair of consecutive numbers approximates phi, or the number 1.618. (5 divided by 3 is 1.666, 8 divided by 5 is 1.60...) By the 40th number in the series, the ratio has stabilized at 1.618, which is accurate to 15 decimal places. You can draw a rectangle divided into squares, the ratio of the side length of a larger square to that of the immediately smaller square is the golden ratio of 1.618:1. A Fibonacci spiral is formed by connecting the arcs , or quarter circles, joining opposite corners of squares. Photography's golden mean and rule of thirds don't quite line up, but they're close, so you can imagine the rule of thirds and then a Fibonacci spiral close to it, and you'll be pretty well defined . It's a tool you can use that will make your images pop! Try it or...... middle of paper ......
