I've just come back from a very enjoyable long weekend in Rome. (Enjoyable that is except for the misfortune of my girlfriend who got food poisoning on our last day and had some pretty serious conversations with the airplane bathroom...)
We often see, "Where can I get film while travelling in...," questions in the forums. So here's my answer for Rome.
I ran out of film while there and, much to my surprise, stumbled on a groovy little outfit who stock all sorts of films and related things. Alessandro allowed me to keep shooting so it seems fair to give him a plug in return. His outfit is called ars-imago (http://ars-imago.com).
