Bokeh, that is, background blur, has become the most important feature of smartphone cameras in recent years. We take care of the popular feature for you.
There is no need to explain how successful mobile phones have become when it comes to cameras. This issue, which I have mentioned from time to time in this column, has now become a very serious area. Today, cell phone cameras have already replaced cameras in terms of daily practical use. Of course, even though cameras are still used in studies where expectations are very high, mobile phones are far ahead in terms of practicality in daily use.
What is bokeh? What does it do?
One of the most important features of mobile phone cameras in the last 2 years is Bokeh, in other words, blurring the background. The definition of this effect on Wikipedia is as follows:
Bokeh or bokeh is the blur effect that occurs in the photo as a result of the settings such as the lens selected by the photographer and the aperture of the unfocused parts while the photograph is taken.
The definition is fine. What he wants to say is that the areas outside the focused area are made blurred by the person taking the photo, optionally. This effect is mainly achieved by the combination of aperture, shutter speed and focal length. Bokeh effect, which requires intermediate or advanced photographic knowledge, is achieved by controlling the entire clear area in front of and behind the subject in focus in a photograph called depth of field. This feature has been offered by cameras for many years. Even in the absence of digital photography technologies, blurring the background was a method known as the photographer’s expression style.
As you can see, it’s a bit of a technical issue. But mobile phones have simplified this technical issue so well that it is now possible to blur the background with a single touch and focus attention on the subject (which is generally used in selfie shots).
Digital and optical Bokeh
Generally, two types of Bokeh effects are used in mobile phones. The first is with digital software. The second is the Bokeh effect, which is provided with hardware, ie optical support. Because the Bokeh effect, which is given digitally, is software, it may not always give very good results. However, today many phones or applications (for example Instagram) can give this effect software. I would like to point out that the results were generally successful.
Hardware, that is, optically supported Bokeh, can be given thanks to the devices called dual cameras and that have dual camera technology on the back or front. Since this feature is hardware, the results are generally good and it is possible to reduce and increase the blur effect after shooting in many devices.
Why do we need Bokeh effect?
The main reason we need this effect is to make the objects in the background appear more concise and to focus our attention on the subject that we make clear in the foreground. However, when the intensity of this effect is exaggerated, strange and unnatural results may occur. Therefore, we recommend that you use this effect in a balanced and logical way. The extreme blur effect creates unnatural images, which is not what is desired.
If you are a Bokeh enthusiast, my suggestion is to buy a dual camera phone and enjoy this effect. Although software solutions save the day, the real effect and realism come with phones that offer dual cameras on the hardware side.
Although the use of this effect varies from phone to phone, it is worth mentioning that it is generally known as Portrait mode. Phones with blur feature can generally use this feature in Portrait mode.
The Bokeh effect, which will be preferred to obtain different frames and try new ways of use, seems to become more common in the coming years. Until a different technology comes in its place.
May your light be abundant…
