effects of cloning brush goes beyond the brush circle

[srg]

While working with the clone tool I noticed that the effect of the brush goes beyond the limiting circle. this is annoying since it prevents a clear selection of the area to be brushed on.

You're not showing which brush you're using and what its settings are.

As Loukash said, the brush is probably a soft brush, either by the brush „image“ itself or by reduced hardness settings.

it is always advisable to use the non-destructive workflow:

• add a new pixel layer
• set clone tool source to current&below or layers below.

this allows to inspect the editions separately, e.g. a soft brush will create a soft result on the new pixel layer

It is a soft brush but I thought that the circle was the limit of the brush effect. It was logical in my mind even when working in a non destructive way with a dedicated layer.

The outline shows roughly the 50% opacity topology line. Outside below, inside above this threshold.
