Photographing Elemental Silver



Elemental Silver
You may remember that last time we said it is was lustrous, shiny or white.  I should mention that those qualities make it difficult to photograph.  This is an outcome showing that problem.  The background is black mat board.

Elemental Silver
This is a better outcome demonstrating a bit more contrast making it easier to look at.  Shooting in RAW I have flexability for adjustment of those qualities such as exposure, whites, blacks etc.  I've found that exposure needs to be exposure compensation -1.5 to -2 to start with.  The top capture was ec -1.  The bottom was ec -2.

Elemental Silver



Elemental Silver
Elemental silver is silver that is not chemically combined with any other substances, minerals.
Silver is listed on the Periodic Table as an element with an atomic weight of 47 and is lustrous, a transition metal, shiny or white.  Its symbol is Ag.  It exhibits the highest electrical conductivity, thermal conductivity and reflectivity of any metal.

I bought this "card" of elemental silver samples in June at the fair grounds.  The come from Bulldog Mtn., Creede, Colorado.

According to geology.com Elemental Silver is rare.

Elemental Silver
When found, it is often in the same location with quartz, gold, copper, sulfides of other metals, arsenides of other metals, and other silver minerals.  As I stated above, elemental silver is a pure element.
