Ok, I uploaded the image to give you guys a better idea of what I'm talking about. The one on the top is 300, the bottom is 72. For the purpose of the design I'm working on the bottom would be the most desirable image. When I preformed the stamp filter effect with my image at 72 dpi it came out like white you see on the bottom. When I enlarged the image and bumped it up to 300 I could not replicate the look of the 72 dpi variant no matter how much I played with the stamp filter settings. I'm assuming that its just giving more data cuz the computer has more information to apply to filter too, but I figure there has to create something like the image on the bottom, but in 300 dpi.
