There are many motivations for shooting jpeg with film sims, from just not wanting to expend the effort editing photos to my motivation as a colour-blind person who simply cannot see colour well enough to manually adjust photos. For me, it’s incredible being able to choose a film simulation and be happy with the result even if I know that the colours I’m seeing aren’t quite the same that others will see. It’s the entire reason I bought into the FujiFilm system.
