So in preview you can add a signature PREVIEW >> PREFERENCES>>SIGNATURES The cool thing about this is that it filters and smooths the signature so even if you drew it with a scratchy marker, your signature looks better than it actually is What I'm looking for is a program that can filter and smooth drawings, I do alot of storyboards by hand, and although I can smooth and filter and adjust curves and levels in Photoshop, I'd really like something that can do what is already inbuilt in preview. It would be a massive time saver. Also, preview encrypts signatures and they are at such a low image size actually using preview would be useless. Any ideas? programs or macros?
