Photoshop Tip: Mirror Clone Stamp
Another great Photoshop (CS3 & CS4) tip via John Nack of Adobe. As of CS3 you have the ability to mirror any clone source in Photoshop. It doesn’t seem like it’s a documented feature:
“Open up the Clone Source panel, then specify a negative number for the width value (e.g. just put a minus sign in front of the “100”). Now Photoshop will flip the source data so that you can clone a mirror image.”
This also works on the Healing Brush.
See it in demonstrated in this video by Russel Brown.
