A few days ago I wrote a short tutorial on how to use the “Heal” tool in Adobe Lightroom. The “Heal” tool is however not unique in Lightroom so if you don’t have Lightroom you can instead use GIMP (The GNU Image Manipulation Program) which is a free photo editing application.
Many times when taking pictures outside or when travelling we come home to see that there have been dust or other distracting particles on our lenses that gave blemishes on our photos. If you are using Adobe Lightroom this is however an easy fix in Develop mode.
This is a quick guide to how you use the Heal tool in Lightroom and I am using version 4.1 but the tool has been around since at least version 3. If you do not have Lightroom, please read the article on how to get the same result using GIMP!
