Eric. That was interesting. However I can not match your Preview example trying to follow your settings.

I make the following comments--good learning?

1. With whatever setting in Common, the 3rd and 4th gradient appear to make little if any difference.

2. Can not see any difference by adding Organic 2 to Highlight or Bump which not served just as well by Value?(Or can you explain the Organic usage in mor detail please).
