Using GIMP I masked out an unwanted person who was situated in the background of my image. This person was partially concealed by my subject. I used the path tool to trace the outlines of my subject and then masked out the backgound using clone and heal.
My problem is that this left very sharp borders on some out-of-focus parts of my subject, wich I would like to blur.
My best guess was using the 'paint along path' option while using the blur tool, but this got me insufficient results as the background got blurred without much colour of my subject bleeding into it. I still have all paths used to mask out the background so using these might be a good way to minimise effort.
Maybe someobody can suggest different settings on the blur tool or a method using a gradient along a path?
Ive also tried doing it manually but this takes a lot of time and it would be very practical to know a better way of doing this in the future. This is how the border of the subjects arm looks after the masking of the background
