||After FX Tutorials : Inset Lines
These inset lines can be used as bar separators, a detailing effect and as an add-on effect for interfaces.
These lines appear best when the lines you use are horizontal, vertical or diagonal lines that
are were not anti-aliased.
To create the inset lines, you start by creating black
vertical,horizontal or diagonal lines using
the line tool. Turn off the anti-aliased option
for the line tool. For this tutorial, I used 2 horizontal lines with 2 pixels thickness to sample the inset lines (fig. 2).
Duplicate the current layer then select the layer below the current duplicate.
Inverse the color of the lines on the selected layer. You should end up with white and black lines
on two separate layers.
Offset the white lines 1 pixel down and 1 pixel left using the move
tool and the arrow keys (fig. 4). This may vary
depending on your orientation of the light. If you are placing your
drop shadows on the lower right then you should offset the lines by 1 pixel down
& 1 pixel right and vice-versa.
Change the layer mode of the layers containing the white lines
from normal to softlight via the layers palette.
