1. A digital camera can be very expensive and powerful, but can't catch up with the tones as a film camera, especially in b&w photography.
2. The exposure time for digital cameras are up to themselves and almost less than 10 minutes for the sake of the sensors' safety but for film cameras which are fully up to the situations.
3. Film rolls today are expensive and when shooting, I have to consider the results so that I won't waste money. This always makes me shooting very seriously and meaningfully.
4. Nowaday people mostly use digital cameras, so the old classical film bodies and lens are a difference.
5. Film can be preserved for a long time in proper ways and digital files can loose easily when your saving tools are broken.
