Frequently asked

How do I eliminate uneven paper shadows in the photo?

Increase the tolerance slider slightly until dark paper shading disappears while the dark ink lines remain intact.

Does this keep the natural red or blue color of my stamp?

Yes, only the surrounding background pixels are cleared; the original color of the ink marks is preserved.
