Hi I am drawing with a bamboo tablet a road on a map and the edges of my stroke look bumpy, ie not smooth, using the pencil tool. I have the hardness set to 0. If I hold the shift key and draw parts of the road that are straight I get a nice smooth edge but when I add in the curves I must have terrible shaky hand cos its so bumpy. Is there a smooth tool or something similar?
Have you considered using the Pen Tool (and then creating a Stroke on a Shape Layer or using »Stroke Path«)?
Resolution is set too low. you can either increase the documents resolution (before drawing) or soften the brush.
A 1 pixel brush looks way better than the pencil IMHO.
