The golden ratio, a "rule of thirds" style of composition that's also based on Fibonacci's sequence, can also help you compose a compelling image.
- [Instructor] In this movie we'll take a look at…another nugget of compositional gold.…And that is The Golden Ratio.…Which is designated by Greek letter Phi.…And it's approximately 1.6.…Now for those of you who are interested…the formula is one plus the square root of five over two.…But perhaps more helpfully, it's roughly the ratio…between any two neighboring Fibonacci numbers.…So for example eight divided by five,…or 13 divided by eight.…And you can use Phi to compose your image…by dividing the rectangular frame according to that ratio.…
- [Instructor] So here we're back to the bat fish.…And this time we're going to look at the image…in terms of the golden ratio…instead of the golden spiral.…So here we have overlaid the golden ratio.…Now remember this is a ratio,…so in the center there we're going to define…the distance between those two lines as one.…And if we put that in contrast to the other two sections,…they would have a distance of 1.6.…So we've taken that number Phi…and we've created the golden ratio overlay for our image.…
