I think this should work for anyone who has photoshop and has a good close up of their dog face
find a good close up picture of your dogs face like this
open it in photo shop
go to menu Image - Mode - Gray Scale
then go to Image - adjustments - Brightness and contrast
Change the contrast to plus 99 and bring the brightness down to -30 or so
you can play with these values depending on your picture and what you think you can carve in detail.
and you should get something like this( Collapse )
