I was watching a photoshop tutorial, which was created using Photoshop CS4. During the tutorial the instructor split his brush into two brushes side by side (using a keyboard shortcut I believe).
Does anyone know how this is done in CS6 or what the name of this tool technique is called?
Here are two more photos. The first shows the single circular brush, then in the next frame of the tutorial, it instantly became two overlapping brushes. Could it be that the size of the brush affects the shape? Like if the brush is less than 80px it is a single circle, but over 80 it becomes two overlapping circles?
