Sure! What I mean is that I would like to shoot a 35 mm film roll and then send it to someone so that person can use it again, in the hope that we come up with some interesting double expositions. I would do the same with a film roll shot by you for example. The theme of the photos I haven't really decided on yet but that could be something to agree with whoever decides to participate Hope this makes more sense. My vocabulary in english is a bit rusty sometimes.
