Should you add fake blur to your pictures to pretend depth of field?

The smartphone cameras have been getting some impressive upgrades since last 1 -2 years. And that has replaced carrying your digital cameras around. If you have a descent camera phone, you don't really need a digital camera. But Using a mobile camera does have limitations. It is very difficult to capture the depth of the field using a smartphone camera. The digital cameras & DSLR cameras have lenses that work brilliantly for wide & narrow angles. Whereas, the smartphone camera are equipped with wide angle lenses and tiny sensors. Because of this it is very difficult to achieve a blurred background. Just to add that blurred background effect, people add fake blur with the help of photo editing software, which makes things worse. The photo editing apps or software usually apply a uniform blur effect across the frame. And believe us, it looks unnatural and it ruins your picture completely. You almost end-up making some harsh transitions to your pictures making them blurry which were sharp earlier. Blurring the background is not the way to put focus on the subject. there are other tricks you can apply. If you want to focus on anything particularly in your picture, keep it in the center of your frame. Keep your backgrounds as simple as possible. If necessary, you can move your subject to get a simple background. But never add fake blur to your pictures.
