Every time I draw in my sketchbook, I wish I could recapture some of the spontaneous lettering sketches I do at a larger scale. Recreating spontaneity is extremely hard, and a bit pointless from a creative standpoint. That's why I don't even bother anymore, and rely on technology to do it for me.
That's when Photoshop steps into the game: with a scanner and a little Adobe magic, you can cleanup a tiny little pencil sketch and output it at a much larger scale. How? Let me guide you.
