Bokeh isn’t the amount of blur in the foreground or background of a subject, nor it is the blur itself. It is the quality of out-of-focus or “blurry” parts of the image rendered by the camera lens. Bokeh came from the Japanese word, boke, which means “blur”.

For the longest time, the beautiful blur effect was exclusive to expensive DSLR cameras. However, it’s possible to capture the bokeh effect with smartphones like the Vivo Y91 these days.

Bokeh and lens design

A lens’ diameter and focal length play a role in creating the bokeh effect. The width of the lens affects the speed of the light rays, which also changes the focus of the objects. As for the focal length, the higher it is, the more selective the focus.

The lens used in smartphones are different from DSLR cameras; they are smaller, and their focal lengths are shorter.

Bokeh in smartphones

Smartphones may not have the best lens like DSLR cameras, but they have a lot of computing power. They can also reproduce the bokeh effect with image processing.

Smartphones that achieve the bokeh effect via image processing do it by distinguishing between the background and foreground and specifically blurring the background. The disadvantage of imaging processing is the smartphone may not be able to identify hairs and blur it together with the environment. This problem also occurs with glass.

Dual cameras for bokeh effects

Smartphones with dual cameras can achieve the bokeh effect with the same or different focal lengths. Examples of phones with identical focal lengths are Huawei Mate 10 Pro and Honor 7X. On the other hand, iPhones and the Galaxy Note 8 are some of the smartphones that use different focal lengths.

Conclusion

While smartphones still can’t replicate the exact bokeh effect like DSLRs, the technology has definitely improved.
