Another test today to get more gold. On wood in the sun the colors are very accurate using the Nikon 7200. You can see the original piece is very close and is extremely close in person. The test piece is a little more gold. Even though the first parameters are closer to the original, the customer has chosen the more gold version. I can't blame them, it's a beautiful, subdued bronzy gold.
One more test to replicate the gold on a perfect surface, then one more on an entire manhole cover assuming all goes well, the set of 4 9x16 Club Sports.
