Quarter Dollar

This image was made using 15 exposures, each at ISO 100, f/9, 1/2 sec using a single CFL approximately four feet away, plus whatever other natural light that was available. I used my NEX-7 with Sigma 105mm macro lens using a Really Right Stuff B-150B focusing rail mounted to a Really Right Stuff tripod.  A 12kg kettlebell was hung from the tripod for extra stability.

The exposures were blended by hand in photoshop.  I tried using Photoshop’s focus stacking tool to blend the images, but saw some strange (and unpleasing) artifacts.

I used this as a test of the focusing rail and to obtain practice using it.
