|Symmetry (from the Greek: "συμμετρεῖν" = to measure together), generally conveys two primary meanings. The first is an imprecise sense of harmonious or aesthetically pleasing proportionality and balance; such that it reflects beauty or perfection. The second meaning is a precise and well-defined concept of balance or "patterned self-similarity" that can be demonstrated or proved according to the rules of a formal system: by geometry, through physics or otherwise.|
Although the meanings are distinguishable in some contexts, both meanings of "symmetry" are related and discussed in parallel.
The "precise" notions of symmetry have various measures and operational definitions. For example, symmetry may be observed:
with respect to the passage of time;
as a spatial relationship;
through geometric transformations such as scaling, reflection, and rotation;
through other kinds of functional transformations; and
as an aspect of abstract objects, theoretic models, language, music and even knowledge itself.
This article describes these notions of symmetry from four perspectives. The first is that of symmetry in geometry, which is the most familiar type of symmetry for many people. The second perspective is the more general meaning of symmetry in mathematics as a whole. The third perspective describes symmetry as it relates to science and technology. In this context, symmetries underlie some of the most profound results found in modern physics, including aspects of space and time. Finally, a fourth perspective discusses symmetry in the humanities, covering its rich and varied use in history, architecture, art, and religion.

lack of focus in the center
I like the pattern and colors.
WOW ROBERTO. This is spectacular. Magnificent color and detail. Fatnastic shot. TFS, Lori
Hi, Roberto -
I agree with Ber. The narrow DOF had you choosing between focusing on the petals or the center. But very eye-catching colors and pattern.
oh how i would love to have this on my wall...
A very impressive shot with a burst of colors. Petals are sharp but I think you should have focussed on he center of the flower.
