Thanks for the comments, guys. I'll try to answer your questions:
Mike, I used one of Dave's beading tools and a lot of sanding! I really like his
beaders.
Prashun, no it was actually a focusing issue. I try to focus mid-bowl but I think my eye just picked up the rim. I shot these indoors, but usually use morning sunlight outside. These pictures were lighted with an LED Ottlight my D-I-L has. I use GIMP to crop and set white levels. I had to go back and scale most of these to get SMC to allow me to upload them.
Paul, that's what I paid for this billet.
