With Clipping Pilot you will be able to cut any image or figure out of a photo to use it in another image, as well as allowing you to save the cut out objects. On the other hand you will be able to apply all kinds of effects to the background of your image. Darken the background, make the image blurry, apply colors...
Clipping Pilot is capable of detecting the edges of an object to make it easier to cut something out, even though you will be able to do so manually if you see that the result isn't what you desired. After that you will be able to include it in another image with the orientation and size that suits you best.
So as to avoid losing a single second, they have added several simple tutorials explaining how to cut out objects and paste them on top of other photos. They will solve you more than one doubt you may have and they will allow you to use the software's full capacity from the first moment.
