sleek ridge
Hello! I'm trying to edit an image of a piece of paper to highlight the words on it. See reference photos below.
I don't know the term for it so I don't know where to start searching. When I try searching for "Make image black and white for documents" I just get fed the generic grayscale filter. Could anyone point me to the direction on where I can learn how to do this, or better yet, how? Thank you.
