Dark sun

Well, I had another go at the question of digital vs film photography today, with filom coming out on top (somewhat retrospectively).

In 1994 (I think) we had a solar eclipse in southern Ontario, which I photographed with the old Nikkormat, a telephoto lens, and a teleconverter. I don't remember the details, but I'm pretty sure I was working with the smallest possible aperture setting and the fastest shutter speed. I remember aiming the camera just by using the shadow it cast upon the ground (easy as I had the camera on a tripod). Tragically, the time of totality was blotted out by cloud cover, but I did take a number of pictures as the eclipse progressed.

Scarborough, 1994

The above pictures were scanned from slides taken during the eclipse all those years ago.

Below is the best I could manage today. Of course, I left the DSLR in China, so this is really just a point-and-shoot camera.

I haven't managed any form of post-processing that makes the sun appear like a crescent, although the lens flare at the lower right does have the approximate shape that I obtained through a pinhole projection.
