I use a combination of (1) a dual photo frame for the ability to move the glass at will, (2) one jansjo for direct, movable lighting pointing directly to the glass, (3) a larger daylight bulb lamp that has its light bounced
to the right direction via one of those tri-fold boards + aluminum foil, and (4) an otherwise blacked-out room. Slight changes to the angle of the jansjo is all that is usually required between coin shots.
Without axial lighting, the toning on this one is barely noticeable:
Always room for improvements, but this at least gives me the ability to show things like the speckled black toning on the Franklin, and proof surfaces like the other two.
