I setup my F6 to shoot a multiple exposure on a single frame of film, trying to catch the eclipse from start to end. But I wasn't going to put all my eggs in one basket so I shot a number of digital shots with our D300 as well. Both were on tripods.
I was using live-view mode on the D300 to compose via its LCD screen and take shots. Then I checked for artifacts, camera movement (some shots were over 1 second long), and exposure via the histogram.
I started using a few neutral density filters and stopping down to f/32, but that result disappointed me. It was full of artifacts from an extreme overexposure of the sun despite my attempts to reign in the light.
I had purchased a few "safe for eclipse" solar viewing glasses which we were using to observe the eclipse as it happened. I stuck one in front of my camera (instead of the ND filters) and amazingly it produced better images!
The above is one of my favorites, and I put a few others up in this Flickr set.
Now I just have to wait for my film to come back to see if my multiple exposure worked out.
