The One-Layer Procreate Shading Trick for Comics

One-layer cell shading in Procreate for comics and manga. Fast, clean, and you can still mess around without wrecking your flats. In this one I walk through a simple Multiply + mask method I still use when I need pages done quickly.

Same shadow color over the whole piece, so the lighting stays consistent. Then I flip it and carve the light out of the shadow for darker scenes.
