proportion and balance
A mysterious ratio of 1:1618 hovers between any two numbers in the series, reproducing the harmonious proportion known as "The Golden Mean". Thought to be a reflection of God's divine intention for an ordered cosmos, it was called "The Divine Proportion", and was given the name Phi.
(roughly 3 to 5) has intrigued mathematicians and philosophers for centuries and was utilized by artists and architects in ancient Greece and Egypt. It can be observed in plant and flower design, proportions in the human body, and almost everything considered beautiful in the natural world and it is seen in the incremental spiral of the Nautilus shell.
Fibonacci spiral design demonstrates nature's way of building quantity without sacrificing quality. It has been deemed the most perfectly harmonious relation between a whole and its parts and is universally pleasing to human sensibilities.A well-proportioned human face adheres to this ratio. The dancing Shiva of Hindu mythology holds a Nautilus shell in one hand as an instrument through which he initiates creation.
Rule of Thirds and Balance
The rule of thirds says that most designs can be made more interesting by visually dividing the page into thirds vertically and/or horizontally and placing our most important elements within those thirds.For the rule of thirds, imaginary lines are drawn dividing the image into thirds. The most important elements are placed where these lines intersect (see diagram a.) In addition to using the intersections, it also helps to use a 2 to 1 ratio (thus dividing the image both horizontally and vertically into thirds) so that nothing is dead center, which makes for a static image. Instead, when placing the horizon line of a landscape, or the eye line of a person, use the lower or upper third as an approximate guide.
