One of the important new features of Adobe Photoshop CC is new additions to the shapes tool. You can now create all sorts of different shapes by rounding each corner of a shape separately.
If you don't want others to use your photos and images without your permission, you can create a so called custom watermark with your name or any other text you want.
Another new and interesting feature of the updated Photoshop CC that enables you to save layers directly into image files without clicking the Save button.
With the new version of Photoshop, you also get a new cropping tool called Perspective Crop Tool which will change the perspective on a image. Check it out, it really is a cool tool.
In Photoshop CS6, the new version of Photoshop, you can use special cropping tool and you are done, but that doesn't mean you cannot achieve the same result with older versions.
