I can think of at least 3 photographer I know who still uses non digital cameras and develop and print in the old ways. Some of them say that the quality is still better in non digital (does that make it analog?!) photography, some say they like the process of printing and developing and the control that gives them.
Most of the small photo printer businesses and also the large chains that offered services to the general public rather then to professional photographers either closed or started printing digital as well as non digital images. Most of the estabilshed very professional printers and developer stayed in business and are still working.
It would be interesting to see what would happened in the next 10-20 years when photography school graduate would not have classic photography training. My guess is there would always be a small market for non digital printing and developing, just like there's still a market for vinyl records or fountain pens.
