What is Bokeh?
Bokeh (from the Japanese ‘boke,’ meaning blur or haze) refers to the aesthetic quality of the out-of-focus, blurred portions of a photograph — particularly the background behind a sharp subject. While ‘blur’ is technical, bokeh refers to the quality and character of how that blur looks: creamy, smooth bokeh is highly sought-after; harsh, busy bokeh is considered unflattering.
Why It Matters
Beautiful bokeh is one of the most desirable qualities in portrait, product, and lifestyle photography. It naturally separates the subject from distracting backgrounds, creates a sense of depth and dimension, and signals a premium production quality that smartphone cameras have historically struggled to replicate (though modern computational photography is closing the gap).
How It Works
Bokeh quality is primarily determined by the lens aperture (wider = more blur), the number of aperture blades (more blades = rounder, creamier bokeh discs), the distance between the subject and background (greater separation = more blur), and the focal length (longer telephoto lenses produce smoother bokeh). Prime lenses (50mm, 85mm, 135mm) at wide apertures (f/1.2–f/1.8) from reputable manufacturers produce the most sought-after bokeh. Point light sources in the background (fairy lights, windows, lamps) become circular bokeh discs — a commonly styled photography effect.
Real-World Example
A product photographer shoots a luxury candle against a window. Using an 85mm lens at f/1.8, the candle is perfectly sharp while the window light behind it explodes into soft, circular bokeh orbs. The result communicates luxury and warmth — far more appealing than the same candle shot against a plain white background.
