When taking a D3100 out on a short walk to see how its high-ISO capabilities stacked up, I found a teddy bear on the sidewalk. It had a name and phone number on a tag that was sewn on. I sent a text message to the number, and soon the bear was back with little Vera. It turns out that the bear had been with her since she was born, and that the name and number had been sewn on so the bear wouldn't get lost at the daycare center. It had never gotten lost until now, so this was the first live test of the tag - which it passed.
Found: One teddy bear. This photo was taken at ISO 6400, and this is a center crop of the image. The level of detail is surprisingly good, especially compared to the D40 which falls apart completely at ISO 1600-3200.
Entertaining the teddy bear with the D3100, the camera that indirectly caused it to be found.
The teddy bear is relaxing in the sofa, waiting for its owner to come pick it up.
