In fact, mounting a commercial development factory, now that Kodak announced the re-manufacturing of slide film, could be a serious business avenue to investigate for Ferrania.
The developing business would help grow and sell the film business, would be an effective complement to it. A certain and reputable developer would give a certain "base of trust" to the technology, more easily allowing investments by photographers and film producers, both amateur and professional, in this technology.
The uncertainty surrounding the future of slide film, especially regarding processing, will remain a drag on sales.
The move, by Ferrania, to set up a processing service could provide "firm ground", dissipate doubts, and have a "cascade effect" of trust.
Having a laboratory of last resort would help selling slides and that would, in turn, help the re-dissemination of laboratories.
The laboratory needs not be set up in the Ferrania factory, although that would be cheaper. Although more expensive, it could be set up in a place like Rome or Milan or Naples, near an international airport and much easier to be reached by couriers such as DHL or UPS*.
I understand that, for the time being, the Ferrania investment is small, the 6 persons are performing miracles, and we cannot expect more miracles, or more persons, or more capital. What I humbly suggest is to jot down, as a potential future avenue of business expansion, a developing business because that would, IMHO, greatly help the slide business and therefore the future of Ferrania. It would constitute a solid basement for the rest of the "building".
* Maybe somebody working in the logistic industry can give insight on where to strategically place such a lab. Maybe a long-term convention can be signed with people like Amazon to provide a reasonably cheap courier service as a low-priority "piggy-back" to services like Amazon primes, exploiting the slack of the primary service? That might imply placing the laboratory near a logistic structure of Amazon.
