I have about 12 rolls of Ilford SFX which I plan to shoot with my Contax NX and my new Russian Horizon S3 Panoramic camera. I will use a #29 deep red filter on the Contax lens, but not on the Horizon, simply because such a filter doesn't exist. Should I use the supplied yellow/green filter on the Horizon, or just shoot "naked"? When I process the films mixed together in a six-roll Nikor tank, will there be any difference in the processing of the mixed rolls? What developer-time-temperature mix should I use? I am looking for "infrared-like" results. I may scan the negs after processing, instead of using traditional darkroom printing. Most of the shots will be NYC street and indoor (Grand Central Terminal, Penn Station, Metropolitan Museum, etc.) shots. Must special precautions be observed when loading and unloading this film? Any comments or suggestions will be greatly appreciated.
