WHAT IS BOKEH?

Bokeh  is Japanese-originated concept, which describes the appearance, or “feel,” of out-of-focus areas. Bokeh is not how far something is out-of-focus, Bokeh is the character of whatever blur is there. Bokeh is archived by by a camera lens using a shallow depth of field.  Bokeh is also now is used in graphic design to create amazing artwork, background and poster.

In photography, bokeh is the blur, or the aesthetic quality of the blur, in out-of-focus areas of an image, or "the way the lens renders out-of-focus points of light."Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting—"good" and "bad" bokeh, respectively. Bokeh occurs for parts of the scene that lie outside the depth of field. 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 highlights, such as specular reflections and light sources, which is why it is often associated with such areas.However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.

HOW TO CAPTURE "BOKEH" PHOTOS WITH DSLR

With a DSLR camera:

1. Use a lens that offers you the lowest f-stop (personally I would choose my 50mm f/1.4)
2. Put it into AV mode,
3. Set the aperture value to the lowest possible which is really the widest aperture,
4. Now set a focal point,
5. Shoot
