This evening, I turned my coin microscope to the exploration of paper birch bark. I experimented with some different room lighting effects and angles. These photos are not post-processed, except that I had to re-encode them with GIMP.
Paper Birch is quite common in Alaska. One of the most obvious features of paper birch is the thin, wispy bark, which is white on the outside, but peels back to reveal pink and reddish colors.
