Picturing with blurry backgrounds

When you have blurry backgrounds make sure you photograph close to your object and use the selective focus. Pictures with the object in sharp focus with the background in a sort of diffused blur, give a pleasant surreal look.
Below is how you can take pictures with blurry backgrounds
1.Keep the object far from the background. This helps push the background out of the focus.
2.Move your camera closer to the object. This will make the background clutter appear soft and blurred.
3. Make sure to set your lens aperture to a wide setting. Try picturing with a range of different wide apertures, like f/1.8, f/2 and f/2.8. The wide aperture results in shorter depth of field.
4. Focus on a specific section of the object, like a person’s eyes or a center of a flower. This makes the object stand out.

Hi OneDes
for better, use 70-300 mm zoom lens with wide aperture
