I find it interesting that there are people who see the value of digital photography, but not digital sharing/hosting of files.
Outside of instagram which I use as a marketing tool, I'm not on social media, but I really value digital file hosting.
For my photography business, the ability to share files digitally is pretty important. I host files to galleries for my clients to view while I'm post processing, and they appreciate the fact that they can get the on social media as early as the same day...even if they don't have the full album yet, and they don't have the high resolution files.
Once everything is fully processed, then I deliver full resolution files. For weddings, I always send a disk over...and by disk I mean USB drive, because the files typically won't fit on a single DVD-R, and more importantly because optical drives are less common now, but everyone has a USB port. I happen to have a USB optical drive for my macbook pro, and its pretty irritating when I have to pull that thing out in 2019. I'm not going to subjective people to that.
Outside of weddings, I give my clients a choice of hosting the full resolution files on google drive or sending a usb drive. I have yet to have anyone ask for a usb drive for a simple shoot where I'm delivering 50 photos. Google drive is pretty inexpensive. 100gb is $1.99 a month. I purge client files from google drive after a year (I keep them on local drives in case anyone wants them after a year), and 100gb is more than enough.
Most people have pretty reasonable bandwidth speeds these days so downloading photos is a non-issue. If reasonable internet speeds weren't the norm, netflix and all these streaming services wouldn't be dominating the way they are these days.
