Macro photography, is simply close-up photography, usually of very small subjects, in which the size of the subject in the photograph is greater than life size. This usually requires a special lens that is optimized to focus sharply on a small area. What I love about macro photography is that it allows us to see an entirely different world that is filled with detail that usually goes unnoticed by the naked eye.

Angle and Perspective
In photography, the angle of view is that part of the world that is visible through the camera at a particular position and orientation in space. It is most often expressed as the angular size of the view cone, as an angle of view.
In photography, a wide-angle lens refers to a lens whose focal length is substantially smaller than the focal length of a normal lens. This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior and landscape photography where the photographer may not be able to move farther from the scene to photograph it.
Another us is where to photographer wishes to emphasise the difference in size or distance between objects in the foreground and the background; nearby objects appear very large and objects at a moderate distance appear small and far away. This exaggeration of relative size can be used to make objects more prominent and striking, while capturing expansive backgrounds.
The rule of thirds is a guideline which applies to the process of composing visual images such as painting, photographs and designs. The guideline proposes that an image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections. Proponents of the technique claim that aligning a subject with these points creates more tension, enegy and interest in the composition than simply centring the subject would.
Golden Spirals and logarithmic spirals capture our eye and imagination at least partly due to their prevalence in nature. Commonly cited examples include cross sections of a nautilus shell, sunflowers and other flowers, pinecones and the cosmos. I recently discovered that they are often not exactly golden spirals but the logarithmic nature of them still appears natural and sensible.
