Good question, what is the point of shooting using film if the end result is scanned into a digital file?
One of many answer is this. Because a digital sensor -- be it on a scanner or in a digital camera -- does one thing and did it very well: creating a clean, high resolution replica/impression of whatever it's exposed to.
So, when a digital sensor on a scanner is exposed to a developed film, guess what! it'll faithfully replicate all the textures, grains, color-shifts, imperfections, everything that we call film "character" (which comes from the fact that film is chemical-based).
Contrast this with the same kind of digital sensor on a digital camera, it's exposed to the actual scene instead, so it too, will do what it does best, replicate the actual scene without flaws.
This is why people who appreciates the "characters" of film will continue to use film even though the pictures end up digitized.
Make sense?
