What is bokeh?
Bokeh (from the Japanese word meaning blur or haze) describes the aesthetic quality of the out-of-focus areas in a photograph. Good bokeh appears smooth, creamy, and pleasing. Harsh bokeh appears busy, distracting, or edgy. It is a characteristic of the lens, not the camera body.
What creates bokeh
Bokeh appears when you shoot with shallow depth of field — wide aperture (f/1.4 to f/2.8), long focal length, or close subject distance. Points of light in out-of-focus areas become soft circles or shapes.
The shape of these circles depends on the aperture blades. Lenses with more blades (9 or 11) and rounded edges produce rounder, more pleasing circles. Fewer blades (5-7) can produce hexagonal shapes.
The smoothness depends on optical design. Some lenses render backgrounds as smooth, painterly blur. Others produce nervous, busy backgrounds with visible outlines.
Good bokeh vs bad bokeh
Good bokeh: Background melts into a smooth, uniform wash of color. Highlights appear as soft, round circles with even brightness. Transitions from sharp to unsharp are gradual.
Bad bokeh: Background elements retain visible structure and edges. Highlights appear as hard-edged rings or polygons. The out-of-focus area feels busy and distracting.
Bokeh quality is subjective — some photographers prefer slightly busier bokeh for character, while most portrait photographers prioritize the smoothest possible blur.

How to get better bokeh
Use a wider aperture: f/1.4 and f/1.8 produce more pronounced blur than f/4 or f/5.6.
Use a longer focal length: 85mm and 135mm produce more background compression and blur than 35mm or 50mm at the same aperture.
Increase subject-to-background distance: The further the background is from your subject, the more it blurs.
Get closer to your subject: Shorter focus distance means shallower depth of field at any aperture.
For the most beautiful portrait bokeh, use an 85mm f/1.4 or f/1.8 lens, get close to your subject, and make sure the background is at least 3-4 meters behind them.
