This thesis is about covers of books and DVD movies. I have tried to find out if the visual communication of the covers differs between the book and movie with the same story. Do they appeal to different target groups? I have also been trying to find out what designers can do to increase the visibility of covers among others. Are there certain rules to follow for making a cover visible?To reach a conclusion I have been studying components in advertising pictures, since covers work as a kind of advertiser for the product.
