One Dollar Bill (Back), 8.6 Gigapixel Macro Photograph by Gene Cooper

This photograph was constructed from 1,800 individual photographs using a new prototype macro photography robotic system. The technology combines focus stacking, stitching, and a robotic photo rig to create each gigapixel macro photograph. We look forward to developing collaborations and partnerships that will help us put the technology into the hands of the public and welcome your suggestions, comments, and feedback.

Here is some more information about the US One Dollar Bill...

The backs of the bills feature images reflective of the history of our nation: The Great Seal of the United States on the $1, the signing of the Declaration of Independence on the $2, the Lincoln Memorial on the $5, the Treasury Building on the $10, the White House on the $20, the Capitol on the $50, and Independence Hall on the $100. Denominations higher than $100 feature ornate impressions of the numerical value of the note, such as an ornate "500."

A popular and often asked question about design is the one that appears on the back of the $1 note, the Great Seal of the United States. The front of the seal shows an American bald eagle behind our national shield. The eagle holds an olive branch, which symbolizes peace, with 13 berries and 13 leaves. In the left talon, the eagle holds 13 arrows, which represents war. The 13 leaves represent the original colonies. The eagle's head is turned toward the olive branch, showing a desire for peace.

The top of the shield represents the Congress, the head of the eagle the Executive branch, and the nine tail feathers the Judiciary branch of our government. The 13-letter motto, "E Pluribus Unum," on the ribbon held in the eagle's beak means "Out of Many, One."

On the reverse of the seal is a pyramid with 1776 in Roman numerals at the base. The pyramid stands for permanence and strength. The pyramid is unfinished, signifying the United States' future growth and goal of perfection. A sunburst and an eye are above the pyramid, representing the overseeing eye of a deity. The 13-letter motto, "Annuit Coeptis" means "He has favored our undertakings." Below the pyramid the motto, "Novus Ordo Seclorum" means "A new order of the ages," standing for the new American era.

The motto "In God We Trust" first appeared on U.S. coins in 1864. However, it was not until 1955 that a law was passed which stated that thereafter all new designs for coins and currency would bear that inscription.
