From this picture you can see how the manipulation of photoshop and the real image has been used. By using layers of the same image it's allowed Corrado to cut, and chop out pieces of thepicture he wants without ruinging other part of the image. This is the main thing behind surreal photography. Another thing Corrado has been able to do is archive a creepy, or even scary effect to his work. Something which is acompanied with most surreal phtotographs. 

Removing specific parts of the image to give a unreal or un natural feel the photo the main idea of surrealism is to make the audience feel incomfortable .
