I follow Fibonacci’s paradigm when creating golden rectangle art compositions.
The Golden Section is widely used among artists to elaborate or crop their work.
The Fibonacci Numbers and Spiral are popularly related to the classic proportion.
The sequence is a series of integers:
0, 1, 1, 2, 3, 5, 8, 13, 21…
each new count being the sum of its 2 predecesors.
They traditional in our conservative visual expressions like fine arts, photography, cinema, etc..
Overlapping of the mirrored, or rotated image can be used for guidelines for picture composition as in:
Many classical and non academic artists have used and over used that technique to achieve a more balanced image.
Some cameras and art/edition software have, at least one type of tool to help find a better distribution of the main lines and masses in the picture.
The resource is not a canon rule, but it usually helps for better results than if it were not used.
I, myself used it along with multiples like x 2, x 1.5, etc.
The Fibonacci – Golden Section paradigm is, along with the Rule of Thirds (more on the on another article) the most widely used resource for planning an artwork.
If you go to a museum, chase for it and then come back here and tell me about, ok?
