Thanks to all of the helpful posts on the Creek, I braved my first granite tile from HD, and didn't even screw it up. I never would have known what to do, where to start or what to check for without you all even though I have been using my laser for over 4 years.... never did granite before. Of course it's not a photo of a person, but it is a photo of a watercolor painting (baby steps, people!)
Not that this is something I will do often (I think), but now I won't be afraid if someone else asks for one. Sorry the picture is not as clear as it looked on my computer. That's another lesson to learn.
Thanks again to so many of you who generously posted settings, prep procedures, pictures and comments.
cheers, dee
