Well, film wasn't invented until the 1880s, so probably photography was seen as cumbersome and/or expensive to most people in 1868 when glass plates were still in use. I would imagine that digital would have more of an appeal, since it would seem so easy and accessible (and probably because that's what all the kids today are using). Would you want to go back to cast iron stoves for cooking, hand washing your clothes, or having no electricity in the home? I worked in a museum set in the 1860s and did the activities people used to do back then as part of my job, and I can tell you it was not an easy life (unless you were super rich).
