<p><b>Reflectivity</b> 
</p>
The angle made by the light of a scanner to the item being scanned is relatively fixed, while objects and light sources photographed by cameras can be varied to best effect. This can be seen by images of an 1805 Irish penny graded Proof-64 by PCGS. The upper image captured by the scanner shows a high amount of detail, but the surface is a matte brown and no reflectivity is seen. The lower image is captured by the camera and the mirror quality of the surface is clear.
The government of the United Kingdom of Great Britain and Ireland.
