Most people who download an image editing program like GIMP do so to touch up their photos and make them look a little more perfect and professional. One of the main actions that people want to do is remove blemishes such as moles, pimples, or scars. GIMP makes blemish removal a quick and easy process, even for the most beginner-level user.
Open GIMP and open the image you want to edit. Unless you are dealing with a gigantic image to start with, we suggest zooming in on the area that you’ll be working on with the Magnifier Tool, it looks like a magnifying glass in your Toolbox.
Once you have zoomed in appropriately on the area in question, select the Heal Tool from the Toolbox, its icon looks like two bandages overlapping in an X pattern.
With the Heal tool selected, hold down Ctrl and select an area of clear skin that you want to use to blend over the blemish, and click on that area to select it.
Release the Ctrl key, and move your cursor over any blemish you want to remove, and then click on the blemish and it should be covered. If necessary, click once or twice more if the blemish wasn’t completely covered the first time. However, if for some reason you need to click more than three times to cover a blemish, check your settings for opacity and scale.
That’s all you have to do! Just click away and you’ll see those blemishes disappear like magic.
