simple Illustration processing tutorial
偶然翻到了两张以前的图，有群友问怎么做，就写一下简单的教程，方法不是我原创的，只希望能给大家提供些思路。
I happened to see two previous pictures, and a friend asked how to do it, so I wrote a simple tutorial. The method is not my original, I just hope to provide you with some ideas.As a Non-commercial personal exercise only.
It will be processed in about five minutes

step2 Use wood carving filters to do some processing according to the resolution
step3 Use high contrast retention to form black strokes
step4 Use the threshold tool to preserve those black edges
step5 You can adjust some black and white relations, use some filters, curves
step6 Use multiply mode to combine graphics, and then clean up. You can continue painting on this basis, which is really very convenient.
