As we aware that, the blur background of an image can give the impression of depth (Depth-of-Field/DoF) separately for the image. The function of blur background is also viewer can be isolate or separate of an object in image so that attention is not split between seeing an object or background. To create blur technique is more widely used in portraits and still life (which need narrow DoF), and not to be used in landscape or scenery (which need wide DoF). Most of us aware that in order to be able to get a picture of the blur background although many are successful, but some are disappointed because the picture is not as expected. For that it should be noted that the results of a background image can be blur vary, and the levels were different blurnya (ranging from somewhat to very blurry image)
What do you think? How to get nice blurry background in the image?
Have you ever experienced any problem to get this?

Hello Omchesunce, yes, selective focus has been a technique used since the dawn of photography, right from the early days of the old wooden gass plate cameras.
A problem with modern day photography is that the smaller and more high tech cameras get, the more difficult effects like that become.
The two criteria for depth of field are focal length and aperture and as camera formats got smaller over the years so did the focal length of the lenses, resulting in larger depths of field.
You will find that the effect is easier to achieve with a longer lens on your camera or the optical (not digital) zoom set to the highest.
Another benefit of using a longer focal length is that with fairly close cropped studies You are a little further from the subject and have better lighting options with less chance of masking ambient lighting.
