Birdwing butterfly

The largest group of butterflies in the world is called 'birdwings', and this is one of the most beautiful. The Latin name is Ornithoptera primamus. Females of this species have wingspans up to 8 1/2 inches (22cm). This is a shot of a male. I captured it in Iran Jaya, Indonesia, which is the western half of the island of New Guinea. At the time (in the late 90's), I was shooting with the medium format film camera, Mamiya RZ 67, and I used a 250mm lens plus a 500D diopter that turned the telephoto lens into a telephoto macro. My settings were unrecorded, but knowing how I used to shoot, my lens aperture would have been f/32, and for all my wildlife and macro photography I used Fujichrome Provia 100 (100 ISO). The shutter speed would have been slow, possibly one full second, and I of course I used a tripod. Fortunately, there was no wind. I angled the camera such that the film plane was as parallel as possible with the plane of the butterfly to insure the entire insect was tack sharp. In the original, I'd clipped the tips of the antennae plus the tips of the wings because I didn't have the compositional flexibility of a zoom. Using generative expand in Photoshop, I corrected that error.
