Photos from the May 2022 BCCOCO show-and-tell:

These items were photographed with a Kodak 10-inch "ring light" unless otherwise noted for comparison purposes. A couple of items were photographed earlier during testing of the light.

Lighting comparison for Statue of Liberty 125th Anniversary proof medal.
Left photo: Single swing-arm lamp; Right photo: ring light.
In this case, the ring light gives much better illumination.

Ring light photos of circulated 1944 half dollar and proof 1960 half dollar.
The result is satisfactory for the circulated coin, but really impressive for the proof coin!

Single lamp (left) and ring light (right) photos of a Civil War Token (CWT 46/335).
The ring light photos are too "flat" and don't show important details such as the metal "flow lines" on the obverse. This is a drawback of uniform illumination with low relief items.

Ring light photos of two slabbed Morgan Dollars (1879-S and 1896).
The ring light is too small to properly illuminate the entire slab.
The coin itself is OK in both cases, but the cartwheel luster is difficult to see with "flat" illumination.
Note that the 1896 is cleaned and has dulled luster to begin with.

The ring light can give very nice results for some larger medals, including those with higher relief, such as the 1920s American Orchid Society medal at left.
The Apollo space medal at right has some "embedments" of special material which reflect the uniform light quite well.

Finally, this 4-ounce silver replica of a well-known $10 banknote is too big to get a really good photo with the ring light, but a satisfactory result was obtained by tilting the item forward to avoid bad reflections (off of the silver itself and the holder).
