Silver is very difficult to photograph. Especially when flat like a guitar pick. I have a great camera that I purchased just for the best close up macro on the market. I also have two photo tents and multiple backdrops. My lighting is two daylight spiral florescent bulbs in fixtures pointing through the sides of the small tent with the camera tripod above. I have a dedicated area just for the set up.
Here are some random images that stay in my mind this year.
