I've got a clip-art type picture that I am trying to alter. It is a picture of aperture blades that I want to use for my watermark. The problem is that the logo is just too...thick. Basically it's like I have a thick donut, and I want to turn it into a thinner donut. I want to make the "hole" of the "donut" bigger, without losing any of the outer part, but just compress it. I have Photoshop CS6, and I know there has got to be a way to do this, but I can't quite figure it out!
This is probably confusing, let me know if I need to clarify more.
