HOW TO GET SHALLOW DEPTH OF FIELD

In any DSLR camera there is a PORTRAIT mode which allow the photographer positioning his/her subject in a creative way

Portrait mode chooses a large aperture (a small ‘f’ number), which will make the depth of field (the amount of your shot in focus) smaller.

APERTURE MODE

This mode lets you choose the Aperture (the size of the hole in your lens) and tells the camera to choose all the other settings. This semi-auto mode is a great way to control depth of field as it will ensure your images are well exposed. For shallow depth of field and nice blurry backgrounds choose a large Aperture (the smaller the number the larger the aperture). Try taking a few shots at different apertures and see how it affects the background of your shots – this is the best way to learn how to get more creative control in your shots.

WITH MACRO LENS

If you're attempting handheld macro shots in daylight (which is quite doable) I would set the lens to manual focus and the camera to aperture priority at f/11, and then set the ISO in order to get a reasonable shutter speed of at least 1/200s. Finally, don't give up - macro photography is hard and there are far too many people on the net making it look easy! 

TELE ZOOM LENSES

The Lens itself compress the Background and gives you the almost a Plain backgrounds in Dominated colors
