Bokeh Effect

The bokeh effect is a creative element in photography that is created by deliberately blurring the background. The term "bokeh" comes from the Japanese and means "out of focus" or "blurred". Photographers use this effect to create an aesthetic separation between the foreground and background, allowing the main subject to come into focus.

Bokeh is created by using lenses with a large aperture, which makes it possible to capture more light and create a shallow depth of field. This creates blurred areas in the background while the main subject remains sharp. Light sources in the background become soft, often circular points of light, making the bokeh effect particularly appealing.

• Circular bokeh: Occurs when the lens has a round aperture and points of light in the background blur into round discs.

• Polygonal bokeh: With polygonal apertures, the blurred points of light in the background appear polygonal.

• Disc-shaped bokeh: This effect occurs when the aperture opening has a shape with rounded edges, resulting in a circular edge around the points of light.

• Portrait photography: Bokeh clearly separates the portrait subject from the background, drawing the viewer's attention to the face or main subject.

• Macro photography: In close-up photography, bokeh creates a pleasant separation between the focused object and the background, which is particularly effective in nature and macro photography.

• Creative storytelling: Photographers use bokeh to create a dreamy or emotional atmosphere and support stories through targeted focusing.

The quality of the bokeh effect depends on the type of lens. High-quality lenses with special lenses and aperture mechanisms often produce a soft and appealing bokeh, while cheaper lenses sometimes show hard transitions between sharp and blurred areas.
