Inking in Manga Studio
I don’t use any interesting custom brushes in Photoshop, and my Manga Studio arsenal is pretty standard, but here’s a hint: I often want to emulate my traditional inks with the digital instruments of Manga Studio, and so may you. Create a new layer with the Black attribute, and try drawing with the standard Pen, Brush Pen (Light), and a Pattern Brush called Large Airbrush for the scratchy shadows. Adjust the last two with the Change Width option (set Thicken To Specified Width to at least 0.14mm), and the very authentic dry brush will be at your service. You can also try changing the Dark Brush Pen options, but I think that by itself it’s really dull and far too simplistic looking.
