"Powder King" (Note: this article's "powder King", that is, we often say "Coke-imaging", in order to maintain the original flavor of the article, remains "powder King" in this statement), Bokeh, is a recently let many favorite photography have quite a topic of interest, such as the famous Leica camera group has many branches have related feast "powder King", including 75mm/1.4 Summilux M, 80mm/1.4 Summilux R, 50mm/1.0 Noctilux M, and 35mm/2 Summicron Pre ASPH.

Especially the last one and some call it the King of the Bokeh, scenes of the King (Note 1).

As Figure 1, the spot behind the orchids will shape and the shape of the aperture opening.

This powder is on the used the Congress aperture telephoto lens when shooting objects from the object behind the dot laser module rendering out of powder King shape, most people prefer the more round the better, but the more rounded shape, the aperture number of leaves is generally better to, as to why blade number better because more of the aperture blades there will be more like a round aperture hole.

Of course, the purpose of this article is not to flatter Leica lens powder King how good, in fact, many of the camera manufacturers are starting to make this a lens characteristics into the design-time considerations, for the same reason, it is not just a Leica lens, a considerable number of Japan name factory as the lens is excellent powder King, even they will disperse King design lenses foresee as one example, a popular Contax 645 medium camera in the United States in the English version of the specification, as their Lens Bokeh is one of the advantages.

Evidently, this concept has gradually formed.

But this article is to try to make this a confused words borrowed from text and pictures to introduce interested friends know.

Bokeh at first glance this English word I feel it is not derived from the United Kingdom or the United States, Yes, it is not a formal English word, it is from our neighbouring countries Japan, BOKEH, according to read English read method is the BOKE, however this is translated in English, so it's correct read method should be in the English Bo-Ke text to find one close to the meaning of the word Bokeh is not easy to find an English word, Convolution is probably the most appropriate.

Convolution is the meaning of an ambiguous image gradient, real powder King (Bokeh) is in the depth of field image gradually changes outside of fuzzy loose.

Depth of field is a lot of photographic friends ignore important concepts, which more or less and use the auto focus camera and the lens of the camera used some relationship, because the auto focus precision, modern man shot sometimes no longer need to use depth of field to compensate for the error when the coke, our common auto focus lens for depth of field table feet often been spoken of, not to mention the zoom, the zoom lens on the depth of field table size can be said to be a scanty.
