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.
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.
Pretty simple and useful tutorial, where you will open a random photograph with smoke and convert it into something really not friendly for our environment.
