I use the word community in a broad way, for both the cases you mention: photographers that feel themselves as members of the "community" and simple photographers.

The goal of this study is to understand the impact of a conversion device on the base of users and the set of complementary goods of an old declining technology. Therefore, both the types of users could provide me interesting reflections for my analysis.

Francesco,

As a photographer of long standing ,I resent the implication that film photography is "old and declining."

It is very much alive in many many places and used by many photographers In fact, I venture to say that most of the
APUG community uses the"old and declining" process.

Even in the computer age,people still use lead pencils.
