Subject: Lettering on anodized aluminum

I'm looking for descriptions of how to make permanent lettering
on anodized aluminum, brass, or other metal surfaces.

I'd like to approximate the milled or deeply etched letters one
sees on photographic lenses (say the manufacturer or lens type on
the front ring), or the milled divisions on fine rulers.
How are non-flat surfaces handled?  What material is used for
the filler (epoxy pigments?), and is the typical process
a sort of engraving, or milling/grinding with a small tool,
or photoetching?

Cheers,
