My new Nikon D300 showed up today, and of course I had to play. This is an extreme close-up of petals of a camellia blossom fresh from my garden. The flower was wet with rain. To get the effect of light coming through the petals I positioned the flower on some small LED lights, then surrounded it with a black velvet cloth. The point of this style of photography was to emphasize the transparency of the petals.
