So, this is the Golden Ratio.

And I'm confused. So many people talking about the Rule of Thirds, how it can help you to compose a picture, how it comes from painting and other forms of art to photography, the relation to the Golden Ratio, the aesthetics behind it..

So here is my question, what is exactly the relation between this number and the Rule of Thirds? And I mean exactly, this is maths after all.

And another question which maybe related or not to this subject. What are the historical reasons for the 2x3 format of the most commonly used films? I know for example that the paper format of the A system, I mean A5, A4, A3.. formats, are based on the square root of 2.
