I've always though that my lines lack sensitivity on the Intuos and Cintiq. Updating drivers and adjusting pen pressure curves didn't yield much improvement. In the end, I figured it was a lack of skill on my part (although I'm OK on paper) and hoped that things will improve with practice.
Today, I saw this: artiststoolbox.tumblr.com/post…
Turns out I've been using only half of the pressure levels available.
Needless to say, this made me feel simultaneously very dumb and very happy.
So check it out if you've also been struggling with pressure sensitivity on the Intuos Pro or Cintiq.
