Photography, Differences in Connotation The beauty of Bokeh and Blur

What's the difference between bokeh and blur terms? How to get a good bokeh result.

Sometimes bokeh and blur have the same meaning, but if you want more detail, we can distinguish as follows:

Bokeh means part of the photo that is not focused, and has the connotation of beauty. The shape of the bokeh depends on the shape and design of the lens.

A good bokeh depends on the type of lens used. To create an interesting bokeh, it takes a lens with large openings, such as f / 2.8 or greater (f / 2, f / 1.8, f / 1.4 and so on).

The farther the distance between the focusing and unfocused parts, the more bokeh the area.

Bokeh example because of the lens used.

While the blur is a technique to make some areas of the image becomes unclear / blurred with the software.

Blur can also mean motion blur, which is created by the motion / vibration of the camera is recorded when making a photo, or the subject of the photo is moving too fast to be frozen by the shutter speed in the camera at that time.

Examples of motion blur due to camera movement (panning) and swan movement.
