Why do you feel like an antique?? It's the model that is technically ignorant in this case. I mean my GF is 22 and she knew what film was when she saw it, she is not a photographer either. All non photographers i talked to about photography know what film is...But even if this wasn't the case, film is not mainstream anymore, it is now a specialist's tool, you cant expect the every day person who only has a cell phone as a camera to know about such a thing...and even when there was no digital cameras..back in '95 say...i personally had no idea what film was either, all i knew is that i had to load it in my 20$ plastic kodak automatic camera...dont ask me what "iso" was either...i always chose 400 because it was higher than 100 and in my mind that was surely better...right? back then, if you showed me a roll of 120 i would not have been sure what it was...i was in my early 20's too so it was not about being too young. So yeah...not antique...just a specialist....
