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.
