Having trouble drawing long, sweeping, line-work? Curves are a huge challenge to draw with the brush tool in Photoshop, especially if you don't have access to a Cintiq. Instead of using tools like French Curves or ellipse templates, "Lazy Nezumi" empowers Windows users to make beautiful line-work. This application modifies the path of your cursor, smoothing out jitters and hitches in your stroke. It's not a magic bullet, and isn't appropriate for all situations- but it's certainly worth the $30 price tag. If nothing else, make sure to give the free trial a spin.
To Mac users: is there a Mac equivalent of this software? Let us know in the comments. Thanks!
