Images corrupt and apps are unreliable. Your backups may not be backing up what you thought. Websites suffer neglect.
A few years after you die, your files may not even be readable, if someone even cares to look after them.
The truth is, there’s no such thing as an archival digital format. There’s nothing wrong with that necessarily for the photographer. The photographer’s enjoyment is in the moment.
Once a year, put your best images (stories) in a book. It’s not for you. It’s for anyone who enjoys a good story, even long after you’re gone.
