boke
Sample and examples for "boke"
| What the Heck is Bokeh?
|
| (http://www.rickdenney.com/bokeh_test.htm) |
| There is much written on the net about this elusive subject, and I won't attempt to provide the etymology of the word (is it Japanese or not?) to compete with it. Suffice to say that different lens designs have an effect on the appearance of the out-of-focus areas in photographs.
Some photographic styles commonly use selective focus to bring the viewer's attention to the subject. That means the subject is focused but the non-subject areas are not. If those unfocused areas are busy and distracting, the objective of bringing attention to the subject is lost. That's why portrait photographers in particular care about bokeh.
There are a couple of myths about bokeh:
1. Bokeh is controlled by the roundness of the lens diaphragm.
2. Faster lenses have better bokeh.
Both of these are, at the very least, not the whole story, as we will see. |

| What is a close-up filter?
|
| (http://imaginatorium.org/stuff/cufilter.htm) |
| I'm glad you asked that question. As you know, light consists of photons, which bounce around just like billiard balls, and just like billiard balls, as photons travel they lose energy. In fact, this is what we call the "inverse square law" of light fall-off. (Nobody quite remembers how it got that name, but it's probably to do with an obsolete camera that used a mirror instead of a lens, and took square pictures. Oh, and the image was upside-down in the viewfinder.) It means that each time the photon doubles the distance it has travelled, it loses a measurable quantum of energy. And the new "close-up filters" are sensitive to these quantum levels, and only let through photons fully-charged with energy. That's why they let you take sharp photographs of flowers and insects, while the lower-powered photons from the background turn into a kind of fuzz, or bokeh* as it's technically known. The best of it is, of course, that you can skip all the old-fashioned grey stuff below about "focal lengths" and concentrate on being creative.

| Bokeh
|
| (http://en.wikipedia.org/wiki/Bokeh) |
| This article is about the photographic usage of the term "Bokeh". For other uses of the term, please refer to Bokeh (disambiguation)
Bokeh (derived from Japanese, a noun boke ??, meaning "blur" or "haze") is a photographic term referring to the æsthetic quality of the out-of-focus areas of an image produced by a camera lens using a shallow depth of field.[1] Essentially, bokeh is an aesthetic and qualitative measure of light distortion in the out-of-focus areas of an image, and is primarily caused by lens aberrations and aperture shape. |

| Understanding Boke
|
| (http://www.luminous-landscape.com/essays/boke...) |
| Exploring the Out-Of-Focus;Photographers know that one of the characteristics that separates photographic imaging from drawing or painting is the matter of focus. When we humans look at the world about us, our autofocus eyes tend to see everything in-focus. And that's the way artists have usually portrayed our world. While the main subject might be emphasized with brighter colors and greater detail, the less prominent objects were usually still rendered sharply. The lens — even the lens of the eye — introduces an opportunity for selectivity in image-making, portraying objects in the near field and background with a special kind of de-emphasis: out of focus. |

| Lupinus polyphyllus
|
| (http://www.secondpicture.com/blog/large-leave...) |
| My intention was to photograph the summer nature, my mother's Norfolk terriers and test my new Canon EF-S 10-22mm f/3.5-4.5 USM wide angle lens. Despite my efforts I couldn't find opportunate situations to photograph. However, I had dragged photographic gear along so I wanted to photograph at least something. I noticed Lupines on the yard and ended up photographing them with Canon EF 70-200mm f/4L USM tele zoom. This lens captures very sharp photos with a pleasing Bokeh. |
