Photoshop's Clone Source panel can completely change the way you think about Photoshop's retouching tools and allow you to solve complex retouching tasks with ease. If you're not currently using the panel, then you'll be absolutely amazed at how it can transform ordinary retouching tools into something that can scale, rotate and distort source content to make it align with areas that would otherwise be impossible to retouch.
You'll also see how it can remember multiple areas you've closed from and allow you to quickly revisit any of those areas without having to re-establish where you should clone from. In essence, this panel will allow you to take your retouching to a whole new level.
