How To Achieve Nice Bokeh [In Plain English]

Photographers sometimes deliberately use a shallow focus technique to create images with prominent out-of-focus regions. Bokeh is often most visible around small background highlightssuch as specular reflections and light sourceswhich is why it is often associated with such areas. Tobokeru [10] means playing dumb, and toboketa kao refers to a poker face. Though difficult to quantify, some lenses have subjectively more pleasing out-of-focus areas. Good bokeh is also important for medium telephoto lenses typically 85— mm on 35 mm format. When used in portrait photography for their "natural" perspectivethe photographer usually wants a shallow depth of field, so that the subject stands out sharply against a blurred background. Bokeh characteristics may be quantified by examining the image's circle of confusion. In out-of-focus areas, each point of light becomes an image of the aperture, generally a more or less round disc. Depending on how a lens is corrected for spherical aberrationthe disc may be uniformly illuminated, brighter near the edge, or brighter near the center. Lenses that are poorly corrected for spherical aberration will show one kind of disc for out-of-focus points in front of the plane of focus, and a different kind for points behind. The shape of the aperture has an influence on the subjective quality of bokeh as well. For conventional lens designs with bladed apertureswhen a lens is stopped down smaller than its maximum aperture size minimum f-numberout-of-focus points are blurred into the polygonal shape formed by the aperture blades. This is most apparent when a lens produces hard-edged bokeh. Minolta has been on the forefront of promoting and introducing lenses with near-ideal circular apertures sincebut most other manufacturers now offer lenses with shape-optimized diaphragms, at least for the domain of portraiture photography. In contrast, a catadioptric telephoto lens renders bokehs resembling doughnuts, because its secondary mirror blocks the central part of the aperture opening. Recently, photographers have exploited the shape of the bokeh by creating a simple mask out of card with shapes such as hearts or stars, that the photographer wishes the bokeh to be, and placing it over the lens. Lenses with 11, 12, or 15 blade iris diaphragms are often claimed to excel in bokeh quality. Because of this, the lenses do not need to reach wide apertures to get better circles instead of polygons. Some lens manufacturers including Nikon[18] Minoltaand Sony make lenses designed with specific controls to change the rendering of the out-of-focus areas. The Nikon mm DC-Nikkor [19] and mm DC-Nikkor [20] lenses DC stands for "Defocus Control" have a control ring that permits the overcorrection or undercorrection of spherical aberration to change the bokeh in front of and behind the focal plane. It is possible to choose between two diaphragms: one with 9 and another with 10 blades. An apodization filter is used to soften the aperture edges which results in a smooth defocused area with gradually fading circles. Those qualities made it the only lens of this kind on the market from its introduction in to It can be re-purposed for defocus control.

The FE mm F2. Already owns the 90 2. Can't decide if the STF is really worth it I'd give the orange "G" a premium. If the STF is anywhere near the "original" mm STF for A-mount, it may not be exactly "value for money", but it will be exceptionally excellent. It would be great to have comparison shots between the mm STF and another mm lenses to see how the bokeh looks like. I'd still prefer the mm but I'm tempted with this STF. Professional sites need to stop mispronouncing bokeh. It has always been "bo-KAY. Mispronunciation over time becomes the correct pronunciation Let language evolve Just like photography has They also mostly say Nigh-Kon. Prouncing things incorrectly doesn't make one right When I asked about it, he said this is a knee-kon FM. Perhaps in these days those guys learned American English, however in Australia, it is knee-kon. Bo as boring and keh as Kenneth. When speaking at normal speeds and saying "bokeh" in conversations, it'll will end up sounding like "bo-kay" to most people. It's only when you pronounce the word by itself slowly that people will hear it as bo-keh. But you're right, it's technically "bo-keh," not "bo-kay. This is all much to do about nothing So many people call it bocah not bokay Just get over it There are bigger fish to fry Why knowingly repeat a mistake and have it proliferate? What would be the point and the benefit of making a mistake more popular? Yes, there are plenty of bigger things I care about and fight for, but this small thing is a pet peeve of mine, just as you probably have your own pet peeves. If we stopped caring about the little things, they will accumulate and encroach upon us and that's when one day you wake up and realize there are just too many mistakes in the world. Just look at the example of how the ignorant masses have butchered the English language, to the point that illogical mistakes like "for all intensive purposes," or "nip it in the butt," or "irregardless," or "hone in" or "I could care less" are now everywhere. They all started as "little thing not worth caring about," until they start to add up and pop up everywhere. Bocah versus will bokay will not cause the butterfly effect The world will not come to an end because the pronunciation of a word changed over time I've said before, we don't speak old English anymore. The north won the war Take down the flag The list goes on and on
