This is an extreme close-up of an Odd Fellows affiliation pin. I shot it to demonstrate for Creative Close-Ups: Digital Photography Tips & Techniques how close you can go by reversing a lens using a lens reversal ring to attach the back-to-front lens to the camera. Exposure data: 50mm, lens reversal ring, 1.5 minutes at f/32 and ISO 100, tripod mounted.
The more conventional macro below shows the scale of this photo by comparing the entire pin to a penny.
The Odd Fellows pin belonged to my Grandpa Palmer, who was a member for more than sixty years. Grandpa Palmer, who died at the age of 103, grew up in Kansas before there were cars. Things were changing fast, but the frontier was more than history.
