Anyone here do proper photo engraving on marble (not granite)?
None of that overblown, over-sharpened, thick edges sort of thing.

I'm trying to work out a system from ground up how its done properly.
Setting scan gaps, resolution of image, black levels in editing, etc, etc.
What are the basic steps necessary to achieve good dither for marble.

Don't have much samples to play with, cant experiment forever.

Doing flat graphics is pretty easy, but photos ?...

Running 80W tube with Ruida6442.

P.S. Dear Mr. Sadler, please (pretty please?) do youtube series on engraving stone :D
