To fix dust and scratches from a negative scan use the Heal Tool in GIMP

Next, zoom in. And look for a clean spot close to the dust or scratch you want to get rid of.

You need to set the Heal Tool first

Why are you looking for a clean area first? Because you need to "SET" the Heal Tool

Here's the command to do that...

  • Ctrl + Left Mouse Button (on clean area of image)

What you did here is SET the Heal Tool. Now you can go ahead and Left Click Mouse Button to remove dust close by.

Once Heal Tool is set, you can start clicking on dust to remove it

Again, once Heal Tool is set, you can start clicking on dust to remove it.

Here's another example. What if the dust or scratch is bigger than just a few dots?

You'll need to reset the healing tool more than once if you're working on dust bigger than a few dots

Set your Heal Tool just beside the dust you want to clean. Then SET your Heal Tool by: Ctrl + left mouse button. Then start clicking away at the debris you want out.

But watch out! Don't use the same spot you set your Heal Tool, or you'll get...

Don't use the same spot you set your Heal Tool... move to a new spot

You'll need to RESET your Heall Tool.

Move to a new clean spot, and set your Heal Tool and remove that dust

Move to a new spot, and SET the Heal Tool again: Ctrl + left mouse button. Then go ahead and start clicking away the dust and scratch.

Here Are The Steps Again When Using Heal Tool In GIMP...

  • Find a clean area, close to the dust you want fixed
  • Set the Heal Tool by clicking Ctrl and left mouse button on clean area
  • Once your Heal Tool is set, start clicking on the dust to remove it
  • Careful! You'll need to re-set your Heal Tool quite often
  • So look for a new clean spot, and Ctrl and click on that spot
  • And start clicking on a new dust and scratch to remove it

What if your Heal Tool is too big or small? Here's how to adjust that...

How To Change The Size Of Your Heal Tool If It's Too Big Or Small
