i don't see how one can affect the other. it's up the buyer to decide if they like it. and each thing requires a certain level of skill to both make and decide if it's any good. if it was just a machine making the image and there was no user input, it might be different.
as an impact, you can make more with digital. if your an analog person you may be able to do less, you need to keep up. however on the other hand, because there would be less old school people, the buyers who collect things from artists who do it old school will have a higher demand and the prices would go up. like those who still like film, but everyone moved onto digital.
