The smartphone detects the subject via sophisticated algorithms, then creates a background mask and applies a blur algorithm to it. To provide smartphone photos and videos with a more professional look, manufacturers simulate the professional look by digitally adding an obvious background blur. This blur effect (right) is what bokeh is all about! / © NextPit We go into more detail about this in our guide to aperture specifications in smartphones. Since camera smartphones still generally use very small sensors, the natural background blur is barely noticeable in most subjects. This occurs primarily in lenses with a large open aperture in combination with large camera sensors. Bokeh describes the natural background blur of a lens. The word 'bokeh' comes from the Japanese language and means something like 'out of focus, blurred' - and that's exactly what it's all about. What is bokeh and what do you want with it?
