Permanence! I have files (and there are no photographs in digital photography, there are only digital files) on tapes, Zip disks, and floppies that contain files that are lost forever because their programs no longer exist. Looking at a CD or card does not give any information compared with an actual negative or print. An then there is computer failure. Just stumbled across a photo of one of my favorite dogs taken 50 years ago and a candid portrait of wife's cousin taken about 40 years ago when she was young and beautiful. She is giving copies to her adult children. Keep in mind that Hollywood stores digitally shot movies on film and not on digital media.
With film, a screw-up is almost always my fault and not that of a faulty SD card or reader or faulty camera electronics. I do use digital capture, both still and video,along with Adobe Premiere Pro suite, because for some applications I have no choice. Shooting film engages the mind because there are so many elements to keep in mind, the requirements for desired exposure, composition, etc., which are difficult to fix later.
