These two shots are the best photos from a roll of film I shot at the end of November, when I attempted to do a few long exposures. All this means is that the time allotted for capturing the image was greater than a second.
In the case of the first photo, the exposure took about 20 seconds, with the camera mounted on a tripod and the shutter attached to a release cable. In the case of the second, which took me two tries to get right, the exposure was 1 minute and 35 seconds.
I used a Fuji GW670 rangefinder and Kodak Tri-X for these photos. The Tri-X was pushed 2 stops to 1600, which accounts for some of the extra graininess.
