Data point: I have 7T of "photo data". I think some proportion of that is video, but probably no more than 10%. I am quite old and it does include scans of all the film images I've taken since birth, and all of one side of my family's film media scanned, and backups of all the cell phone images from family members' devices. From memory however most of the data comes from digital-era DSLR images which can be 30-40M each. None of this data is stored in a FAANG company's DC.
