Film: Kodak Panatomic-X, exposed at ISO 25. It has been expired 27 years but has been frozen. Slow-speed black and white films survive for years in a freezer. After decades, cosmic rays may cause fogging on high-speed films, but this slow emulsion is still fine.
Film development: Northcoast Photographic Services developed the film in a Hostert dip and dunk system using Clayton F76+ developer. I requested N-1 development (pull 1 stop) but the results were still too contrasty and harsh. Also, the film exhibited some reticulation, meaning a rinse or other chemical was too cold. I did some contrast adjustment and toning with PhotoNinja software.
Scanning: I used a Minolta Dimage Scan Multi medium format scanner at 2850 dpi. To run the scanner requires an old computer with Windows 7 and a SCSI card. The Minolta ScanMulti software was written around 1999 for Windows 98 or NT. To keep old hardware going requires not only the device you want to use but also the appropriate cards, wiring, software, drivers, and operating system.
Update: To compare with traditional black and white film, here is a high-tech digital photograph of the former gas station on East South Street. This was from a Fuji X-E1 camera with 27mm lens.
