Bokeh Vs Sharpness

  

The word "bokeh" comes from the Japanese word "boke" (pronounced bo-keh) which literally means fuzziness or dizziness.

 Bokeh describes the rendition of out-of-focus points of light.

Bokeh is different from sharpness. Sharpness is what happens at the point of best focus. Bokeh is what happens away from the point of best focus.

 Bokeh 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.

Unfortunately good bokeh doesn't happen automatically in lens design. Perfect lenses render out-of-focus points of light as circles with sharp edges. Ideal bokeh would render each of these points as blurs, not hard-edged circles. 

 There is no measurement for bokeh, like everything else in art, you gauge bokeh by looking at the image. So you have it. Bokeh shot makes the footage or pictures more artistic in nature thus increasing the value and aesthetic elements of the subjects. 

 That's why professional wedding cinematographer or photographer would not use normal consumer camera / handycam in shooting. High end devices are their preferred choice, as well as for me. I use Broadcast quality pro handycam Sony HVR Z5E as the main arsenal. Why? Because I do not shortchange my customer. There are many vidoegrapher out there who try to make a living by using recording devices which eventually do not correspond well with the customers' needs. The footage do not distinguish between background and foreground as everything looks flat. Then reality sets in.
