My camera, even set to "macro", can't give a good image of an SMD.
The diagram I linked to in my OP gives a good idea of what it looks like,

Hold a hand magnifying lens over the camera lens for an impromptu macro
set-up. Take shots at different by 1/4 inch measured spacings for future
reference of the exact focus distance.
