Last month, we collected petrified wood bits from Bear Creek, south of Prineville Reservoir in Oregon. The following pieces are one inch or less in size. Getting decent photographs of these tiny stones proved to be a challenge.
I set up a tabletop studio and tried a Panasonic Lumix and a Galaxy Ultra phone camera. I had to keep adjusting the spotlights outside of the studio. Each stone was given a quick spritz of water to bring out their color. After many unsuccessful attempts with both cameras, I finally got some good shots with the Panasonic.
