How I do it: I shoot transparency. You have to get it right in-camera; there's no opportunity for correcting in post (unless you go hybrid). Now what I will do (and this will work for getting the negative exposed the way you want it) is grab the digital P&S and use it like a polaroid. Since the P&S won't show me the EXIF data, and I'm not lugging a computer along with me to capture the sunset, I just dial in different exposure compensation factors on the P&S until I get the look I want. Then I dial in the same exposure compensation on the film camera and commit to film.

Because you're shooting negative film, you'll still have to either work with the lab to get what you want, or print it yourself.
