I want to sketch an image, take a picture with a camera and get black and white line art that will be easy to color in photoshop. The problem is when you take a picture of paper, and adjust the levels, u get a grainy look in the background that is difficult to remove without tedious masking. I also dont have the time to go over the picture with again. Is there a quick and easy method to achieve good line art from a camera photo of a sketch?
