I just don't understand the "WHY" part. Whenever I see something shot on film, the appeal is part nostalgic, kinda like how, if you buy a 250 year old house, you want it to have some rough edges so it looks like it's that old, that it survived the War of 1812 and the hurricane of 1867, not to mention 30 years of neglect before you bought it. The assets of film are mainly about a look someone likes, which they claim is not doable in digital, but probably is, if they were not so wedded to chemicals and film.
I also suspect some sort of emotional attachment to the fact that there's no do-overs in film. If the negative doesn't have what you want....that's it. If your processing is off....that's it too. What film has is something in common with something else....murder. Once that's done, there's no turning back.
I like how digital is not like murder. I can always declare that this version sucks so I'm going back to square one.
