Before we begin, let's talk a little bit about the technique. Bokeh is the visually pleasing quality of an out-of-focus photo.The reason why our phones can't capture blurred lights with its built-in camera is because the lens is set to have a large depth-of-field. It tries to focus in on the entire scene, which is also why camera phones have a harder time focusing on subjects that are close-up. Since we can't narrow the depth-of-field by adjusting the aperture to a larger size (smaller f-stop), we have to bring the focal point to the foreground by some other means. In order to do this, we will need to use a macro lens.
