Here is a set of screen captures on how to use the GIMP Clone Tool.
First of all – GIMP is a bit confusing to work with.
When you click on the Clone icon and move the cursor into the image you get a clone stamp image with “no entry” sign. Confused ? I was, until I looked in the bottom left hand area of the screen, where you will find the very helpful “Tool Tips” that guide you along.
Pick your area you want to take a sample of by holding the CTRL button and mouse button simultaneously down. Then release both and move your cursor to the area you want to “over write”. Click only the mouse button down and hold it down, and “drag” the mouse around. That is the way you can “paint” over top of the distraction. Another technique is to “dab” by repeatedly clicking the mouse button while moving the mouse over the target area you want to change.
Note: On an Apple Mac computer change “CTRL – Click” to “Command – Click”!
Click here to go to the course page. Then scroll down to the bottom, and “right click” the image to download the image to practice on. Example below.
Here is a rediculous example of holding the left mouse button down while wildly moving the cursor around. If you pay attention, you can see the outline of the source area you are copying move around as you drag the mouse cursor around.
Tuesday Feb 6, 2018 –
I am continuing with the tutorial after getting some feedback from Ron. Cloning was very frustrating for him until he realized that when dragging the mouse while holding the left button down the source patch that he had selected moved around as well causing a long streak of source material (with unwanted detail) to be copied over top of the target.
One way to leave the source patch in one place is to “Dab” which means releasing the mouse button every time you copy a patch. This in itself can be frustrating because you keep copying the same original patch over the different target area.
So the trick I use most often is to look for an area that is most suitable as a “source” with a bit of lee way on either side, than move the mouse cursor to the middle of that patch and hold the CTRL or Command button down to select the middle of that patch. Then move my mouse to the middle of the area I want to remove / replace and hold the mouse button down again and move the cursor around no more that the original patch I wanted to copy, of course while holding the mouse button down.
Once I have the patch or multiple patches copied, I use the least “hard” brush pattern to “Dab” the edges of the patch.
It takes a bit of practice, but you will get the hang of it fairly quick.
Here are two screen captures, showing how to change the clone brush settings.
