TJ short stack

Just in time for President’s Day on 20 February 2023, I cooked up a “short stack” composite image of part of a nickel, that is, a five-cent coin in U.S. currency.

The face/head of Thomas Jefferson appears on one side of the nickel. Jefferson was the third president of the United States of America.

Part of a nickel (five-cent coin in U.S. currency).

There are many noticeable scratches on the coin.

The metal nickel has a hardness of 4.0 on Mohs Hardness Scale.

A mineral’s hardness is a measure of its relative resistance to scratching, … Source Credit: Mohs Hardness Scale, National Park Service.

Many minerals/common objects are harder than nickel, such as quartz, glass, and steel, to name a few, and can scratch the coin easily.

Tech Tips

The preceding composite image …

  • was created using four photos shot with my Fujifilm X-T3 camera and Laowa 25mm Ultra Macro lens. The lens was set for 2.5x magnification and an aperture of f/4, the “sweet spot” for this lens. A single external flash unit was used to light the photos.
  • is focus-stacked for greater depth of field. At a magnification of 2.5x the depth of field is extremely shallow. 0.0896 mm (89.6 microns), to be exact.
  • is “full frame” (6240 × 4160 pixels), meaning it is uncropped.
  • was created using four unedited JPG files, straight out of the camera, that were focus stacked using Adobe Photoshop.
