I remember a few years ago I watched or read a tutorial that showed me how I can use the clone stamp tool with a static source point.
What I mean is that the source we indicate with the alt button should stay only on one place while we copy this to other areas of our subject/canvas.
How can I make the source that I set for the clone stamp tool static, so that it doesn't move while I'm copying/painting it on other areas?
There's no way I know of to actually pin the source to a single specific spot, it always moves with the tool as you paint. But you can always start from the same source point.
If you unchecked Aligned in the Control Bar the source always starts from the same location.
