Interesting but not really seeing the beauty of the item.
I think that is the same technique I have seen some people use for contrast with coin varieties. While it might be useful sometimes, I think for "natural material" items, regular color is best most of the time. There just doesn't seem to be enough separation between the item and the busy background. Maybe a neutral background would help?
Interesting images. I could see the potential benefit of viewing using this sort of application.
What is the magnification power used for these images?
