Paul that's a beautiful image - and that test is meaningful to a degree...but there are some differences - specifically apparent print color and brightness/contrast, which you could likely manipulate further in the PMK image to bring it a bit "closer" to the Thornton 2-Bath image.

My gut says you can get them closer...but that the Thornton image would still have some qualities (high value smoothness and delicacy) which makes it very special. Its been a long while since I've souped in any sort of 2-bath soup...and your image inspires me to give this another try! Thanks!
