Tutorial II : Bokeh

Actually this tutorial is make due to some request by some people. So, I willingly make this tutorial so that I hope this will teach them how to make a beautiful and astonishing bokeh.

is an adaptation from a a Japanese word meaning blur. In photography this term is used to describe the quality of the areas in the picture which are not in focus.

There are 3 types of bokeh which is poor, neutral and good.

For poor types(above), there are greatly magnified blur circle showing very poor bokeh. A blur circle is how an out-of-focus point of light is rendered. Note how the edge is sharply defined and even emphasized for a point that is supposed to be out-of-focus, and that the center is dim.

For neutral type, there is a technically perfect and evenly illuminated blur circle. This isn't good either for bokeh, because the edge is still well defined. Out-of-focus objects, either points of light or lines, can effectively create reasonably sharp lines in the image due to the edges of the sharp blur circle. This is the blur circle from most modern lenses designed to be "perfect."

While for good type, the edge is completely undefined. This also is the result of the same spherical aberration, but in the opposite direction, of the poor example.

Usually bokeh will be round or sphere in shape. But we can change the shape by using a customize filters. So, the next tutorial will show how to make the filter and also how to shoot a bokeh.
