My daughter just turned 19. She owns an Olympus OM1 and 3 lenses. Occasionally she will use her cell phone for photos but she really doesn't care much for digital.
I recently photographed my grandson with my Hasselblad 500cm. He couldn't understand why he couldn't view the images on the back of my camera.
Most kids don't understand film because they have never been exposed to it. It's up to us to teach them.
