A snapshot of prehistory

(You're viewing this image at full size.)

This was an exercise in steady hands -- the light conditions were very low -- and, later, in digital enhancement. The trilobite lives at the Adelaide Natural History Museum, and as with all museums, the light is dim. Photography is allowed, so long as flash is not used and the images are not intended for commercial use -- as in, publication (meaning, books, magazines. I can't imagine why a museum would have a problem with a picture being blogged). The film speed on the Fuji 6500 was set at about 800, and still the shutter speed was looooong. The fossil is also quite small; you're on the borderline of macro photography here. The trick was to hold the camera extremely steady. Later, I adjusted the image for contrast and color saturation, and the result is striking. The fossil is going to be something like 300 million years old -- all the trilobites perished in the great extinction 250 million years ago. This one is beautifully preserved. Photo by Jade, 2008.
