The word bokeh is one of my favorites. Bokeh is also one of my favorite techniques in photography. If you're not a photographer or if you know nothing about photography (and even if you do), it's likely that you don't know what this word means. Bokeh, a Japanese word, is a photographic term referring to the appearance of out-of-focus areas in an image produced by a camera lens.
Photographers know that one of the characteristics that separates photographic imaging from a drawing or a painting is the matter of focus. John Szarkowski also talked about this. For those of us who are lucky enough, when we look at the world our autofocus eyes see everything in-focus and this is the way that many artists have rendered their paintings. A camera lens presents an opportunity for selectivity in image-making where we can portray objects in the foreground and background in or out of focus. This is achieved by changing the aperture of your lens - a large aperture shows strong out-of-focus effects while a smaller aperture produces a longer depth of field, allowing objects at a wide range of distances to all be in focus at the same time.
