Create an Engraving in Photoshop: PSDTUTS
I have a new tutorial up on PSDTUTS. It's titled "Create the Classic Look of an Engraving in Photoshop". It shows the absolute best and only way to automate the distinctive texture of engraving in Photoshop (I'm open to challenges!)
This tutorial could be used to make some really awesome fake money, or any number of classic-looking graphics. Enjoy!
UPDATE (09-27-2015): I changed the link to the tutorial since it had been moved.
