Background blur, also known as bokeh effect, can be achieved while shooting or even after shooting your photo, thanks to advances in editing software. Nowadays people may want to have this beautiful effect for a couple reasons like:

Step 1 Creating a depth of field. This is a photography term that refers to the distance between the nearest and the furthest objects that are in acceptably sharp focus in an image captured with a camera. This could be achieved when the background of a photo is blurred to emphasis the main object.

Step 2 Emphasizing the subject. Maybe you find the background not so pretty or a bit messy, or you just want to showcase a portrait or a product. Then blurring backgrounds can help you quickly get rid of distractions in the background.

So if you have a picture and you want to make the background less obvious and put the focus on the main subject, how can you achieve that quickly? If you're on your desktop, then please try out these tools.
