Hi Rob,
not sure of your lighting setup…recall, you are not lighting the piece, but rather what the piece is “seeing”…
ie: light the panel that the object is “seeing”…reflecting…
can angle how the light hits the panel, to get gradients in the reflection…ie: shows the roundness of curved wire versus sharp dark and white reflections…
ie: take a mini mag light and move it around the piece and take note of what happens on the object and where your hand/ maglight is…that is what/ where the object the object “sees”…
