Technical Value I. Rules of Photo Composition/ Technical Qualities.

The rules that we can apply and consider before having some good photo.

LINES

The leading lines is used to emphasize the existence of the tourists.

The wood is used as the framing and border lines to highlight the kid.

Here are some tips about the Leading Lines. The leading lines such as symmetry shot is providing a platform to grab audiences' attention. A well composed photo will lead audiences about where to look by using the converging lines that give a strong sense of perspective and three-dimensional depth. Those converging lines is drawing audiences into an image and control the way people's eyes move around the picture.

Lines exist everywhere, in the form of walls, fences, roads, buildings and so on. Lines can also be implied and perhaps by the direction in which an off centre subject is looking to make audience follows to the guild lines.

BOKEH
The Bokeh is applied by using manual focus mode.
It is particularly created to perform the speciality of the core subject and try to ignore the background by using wide apertures.
Wide apertures correspond with small f-stop numbers, which is 2.8, 3.5 and etc.
Wide apertures offering more depth of field when focused on a subject far away than they do when focused on a subject that's close to the lens.

SHUTTER SPEED
is separated into fast shutter speed (Exp: 1/25s and above) and slow shutter speed (Exp: >1s ).
The function of fast shutter speed is to freeze the action while the slow shutter speed is to show the continuity of an action.

RULES OF THIRD

Rules of third/ point of interest.

Here are some point for rules of third, try to place your subject at the circle sites and avoid them in the middle part. This is because subject which usually placed in the centre of the frame will make the production rather static and boring. Therefore, one of the ways to counteract it is to use the Rule of Thirds, where we split the image up into thirds, both horizontally and vertically, and try to place the subject on one of these imaginary lines or intersections.

The photo composition doesn't have to be complicated. There are some sorts of theories about the "Rule of Thirds" and more complex "Golden Mean".
But if we pay too much attention to strict formulae, the photos will lose any kind of spontaneity.
