Hi Lon,
I'll set up and just absorb each section. See if any "hot spots" attract my attention. I'll deal with each.
I'll see if I need any more shading to pull out contract. Of course, I have to project that because the background isn't yet darkened.
I have to sand off any burrs. There will be hundreds.
Then I must buff the pearl again. Probably mask engraving so as not to erode it.
After that, I have to chemically clean the metal of any buffing compound. I can then apply the background darkening. Clean the high spots. Massage the shading.
Once you think you are almost done, hours still pile up.
Thanks Lon
Gary
