Great Wall coins are made from copper-nickel alloy. Various toning forms on this material. Some coins are uncirculated with nice luster bands. It is a tough job to highlight both the colors of the toning and the luster band at the same time. I have been trying different ways for that purpose, but so far have not been very successful. Any help from forum members would be greatly appreciated.

Those are great photos and I will be interested to hear what others think. Can you include some information about what you changed between the 3 photos? Different lighting, or different camera settings, or some combination?

Capturing toning requires lights be at a very high angle and diffused, and to use relatively small lens aperture. Capturing luster requires a specific range of angles (both vs coin and vs each other)and minimal diffusion. I developed the "smile directors" specifically to overlap between these requirements. I don't know of a technique that can give BOTH great toning (axial is best) AND great luster (single small light is best) so you need to find a compromise between the techniques. The PCGS system does a good job, and seems to blend axial or pseudo-axial with small lights to give a mix of the two techniques.

The lens mounted diffuser seems to be doing a good job. Which images should we compare for before/after?
