Yes. As much as possible. Film has a very limited range compared to our eyes and a creative decision has to be made how to fit a wide range into the film's dynamic range. If done right, it sets up the best conditions to extract the information when printing in the darkroom or scanning. A straight print rarely looks good, but properly exposed and processed film increases you chances of getting what I want. But not always.
Actually I would suggest that negative films are not that limited, its the paper that is most limiting.
