Very Cool!!!

Nice shot of the symphony! I've always wanted to try something like that with a music group but haven't gotten around to it...

[David R Munson]

Awesome shot, Mark! Were you able to do any testing ahead of time?

[vphill]

Thanks everyone.

David, No I calculated the shot about a half dozen times. I had two stacked circular polarizers (need to get myself some ND filters), I was trying to get an 8 min exposure which with the reciprocity failure I've been using for FP4+ would make 1:15-1:50 completely reasonable as far as times. I tripped the shutter and got on stage. I'm fourth bass, can you see me?

From a long time ago, before I started keeping track of exposures, etc. Cropped from a 4x5 negative (150 or 180 lens). In 1980 it could have been Kodak Royal Pan film, perhaps developed in Microdol-X (1:3)...but I could be wrong. I was not aware of what reciprocity failure was at the time, so I lost some of the detail in the shadows. The exposure time was probably 10 to 30 seconds at f64, but probably closer to 10 than 30.

But I have always liked the image -- it started me on an exploration of the panoramic landscape.

From a scanned silver gelatin work print.

Nice, really nice.

vphil, great shot as well.

Northern Michigan, Velvia 8x10, 250mm fujinon, nd6.0, and a bit of vignetting from the small filter. About a minute long exposure.

Looks like your film slipped in the holder during exposure. I've had that happen more than once. What I do before making long exposures is tap the holder edge that will be at the bottom sharply on the palm of my hand. I've not had film slip since doing this (35 years).

Think about how migh the bridge would be moving if it was the bridge. 10, 15 feet or more? Cars couldn't drive on it if it moved that much.
