Greater picture detail in film - to get the same detail you would need to buy a high end digital camera. Film is easy to store - negatives hold a lot of information in a small place. Film is a consistent format that does not change or deteriorate. Digital formats and media can change making your photos inaccessible in a few years. Film cameras are cheaper - disposable cameras cost little more than film. A mechanical camera does not need batteries. Film can be scanned if you want to manipulate images on a computer.
