I think the point of confusion here is that some activities create
*multiple* entries.  These entries, as output of a single activity,
are closely associated with the session which created them.  In this
case, the session is the "roll of film" and the associated entries are
the individual photos.

Is there a way to associate these that maintains the security model?
