Very Wide Panoramas: 9:1 Aspect Ratio Project
In my last blog post I detailed spooling 35mm film onto 120 film backing paper to achieve a 5:1 aspect ratio panorama. In this one I used the same technique with 16mm film to get an even wider aspect ratio of 9:1. In this case I used some black and white movie film from Kodak called Double-X 7222. I used it in my Minolta spy camera which I discussed in a past post . It is a 200-250 ASA black and white film. I have a small spool of it in my freezer. I exposed it at 200 ASA (also bracket +/-1 stop but box speed seemed best.) I made some test exposures on a bittery cold and windy day. I decided to stay out of the wind and chose as a subject an old quarry wall. It was in a sheltered forested valley so wind was not an issue. I did find that it was getting quite dark. The light made focus difficult. I ended up metering between 3 and 5 Ev. This gave 1 minute at f32. I didn't have reciprocity data for this film so I used TMAX 100/400 values which indicated 1' 24". I deve...
