In Photoshop CS6, I want a B&W gradient along a path, with a uniform width, the gradient always perpendicular to the curve. I drew a path, used Stroke Path, with a brush that's a very tall line. I got close. Two issues: 1) the gradient decreases in size (?) but Shape Dynamics is off, 2) the gradient is always vertical (see pic). I want the gradient (the vertical brush) to be perpendicular to the path.
