Don't worry Blender fans. Nicholas will be back next month. His excuse this month was something about getting married.
This month we’ll look at restoring old and damaged photographs using GIMP. For this example I’m going to use a photo of my late grandfather as a child.
It’s a very old photo taken in the early 1900’s so the dark and light colors aren’t as pronounced as they could be, but even fixing that won’t repair the damage, but GIMP will. Once we have the photo restored we can do some basic color correction to it.
The Clone Tool
In the tool box, choose the Clone Tool icon (shown left). What this does is let you select a source within the image which it will clone to wherever you paint. Let’s start easy and go with the crack to the left of his head. There are no details in/behind it, so it should be easy to repair. Here’s the steps I take to repair it:
I select the clone tool then a suitable sized brush (with a soft edge) which has a diameter larger than the width of the crack. You’ll notice that the pointer has a stamper icon beside it and a no entry icon. This is because I have not chosen a source yet, so the tool is not ready to use at the moment.
To choose a source, I hold down CTRL and left-click above the crack at the point where I want to start from. Please note: the source you choose has to match where you’re going to clone it. If I chose a source above the middle of this crack then go from left to right it would not match.
With the source chosen I now hold down the left mouse button and draw over the crack in one motion. If I stop-start, it will reset the source and not match where I am in the motion.
And that is the magic of the clone tool. You follow that procedure for each crack or blemish on the photo. The tricky part arises when you get to things like the vertical bar in the window backdrop; it must match, and it will take a few tries before you get it; the source will need to be above/below where you’re painting.
It’ll take a bit of practice, but you’ll get there in the end. Middle right what I have after a few minutes of Clone Tool action.
After I’ve removed all the cracks I apply some basic color correction (shown bottom right).
Obviously you remove all the blemishes then do your color correction, but I just wanted to give you a brief introduction to the power of the clone tool.
