The image blur filter works with the depth map for locate the pixels in the image . Therefore, when working with this format, you can use the crosshair to determine the epicenter of the blur you want to create.
To create depth maps, you can use layer masks or alpha channels and work on the design of your image. Where black areas of the alpha channel are treated as if they were the first printed sheet of the image. And the white areas of the layer masks will be treated as distant, which will make it easier to blur the image.
