Week 5 Assignment 1: Fibonnaci's Ratio

Fibonnaci's ratio was found by Leonardo Fibonnaci around 1200 AD (source). He determined there is a ratio present in nature that the eye sees as beautiful. The ratio is 1:1.61~.

Products, buildings, works of art, and photographs have been modeled after this ratio. Have an iPhone? That's in accordance with the ratio.  The source I used calls the ratio, "the rule of thirds on steroids".

When you take the sweet spot of the ratio and recreate it four times into a grid, you get something that looks similar to the rule of thirds grid, however it is different.

Here are some examples of the ratio put to use in regard to photography:

I can't even imagine trying to keep this in mind when taking photos. I think for now I'll stick with the rule of thirds, but this is great to know about. It matters because it is what we consider "beautiful".

  1. I found this very interesting and useful I am going to try and keep this in mind when taking pictures. Thanks for sharing.

  2. Instead of the "Rule of Thirds" being superimposed on your viewfinder, why not this?

    This is great information, thanks for sharing it!

  3. Fibonacci is a sequence, the Golden Mean is a ratio, but they are related. A Fibonacci sequence will approach the golden ratio as it progresses to larger numbers. The rectangle is a based on the golden mean, while the spiral is a Fibonacci sequence. As far as the rule of thirds is concerned, if you look at the spiral and where it progresses to, it is actually pretty close to the sweet spot as far as thirds are concerned. You will find both in nature and design in a whole lot different places. My favorite is the spiral on a fern as the leaves are first emerging, but I also like the shell, which you also have pictured. I mentioned Degas in my post about layout, design, and the like, he used the golden ratio in a lot of his works.

    1. The Greeks discovered the golden ration long before Fibonacci was ever born, here is more on the golden ration at Wikipedia:

      Here is the Fibonacci sequence, which is simply a mathematical curiosity:

      Again the two are related, but different concepts altogether.

    2. Hey Jason,
      Good point, I should have emphasized that the golden ratio and golden spiral are not the same thing. Good explanation.

  4. It's interesting that we both stumbled on the same article. In my explorations this week I have found that playing with the golden ratio is much more fun and interesting than shooting for thirds. I agree with you that keeping the exact ratio in mind while out shooting is hard, but that's why (insert deity here) created photoshop :) If you go to the crop tool you can change your crop to the golden ratio/spiral.
