Thanks a bunch! Also (this is most likely just wishful thinking) but is there a site that gives a (brief) summary of changes to the photoshop system. I'm using CS6 for instance but the tutorial I'm using (Ascension's antique map tutorial) explains the process for an older version. I've had trouble finding the airbrush and (still unresolved) have no idea where to find square brushes in CS6. It's so frustrating I'm considering looking for an older photoshop version (but I don't even know the one he used for the tutorial).
