Good job; you’re right, they did turn out decently (given the apparent source quality). That’s gotta be much faster than scanning. That’s cool that you’ve got photos from your grandparents’ earlier lives; I’ve got a few of mine but not many. Did you do anything specific to tweak the color of the backlight on the tablet?
I’ve got bunches of old photos I need to digitize as well at some point. It’s a matter of making time to do it, but the longer I wait, the more they seem to deteriorize/fade so I keep telling myself I need to get to it.
// FYI, the link that is your setup goes to a Yahoo signin page. The link to the scanned photos works though.
