If you shoot stills and want the positives of film and not the negatives, try my open-source photo editor Filmulator, which simulates the depletion and diffusion of developer liquid to enhance color, improve local contrast, and reduce global contrast, without any of the halation, grain, scratches, color shifts, or any of that nonsense.
Aside from the draw of the film simulation, I've designed it to have a very streamlined user interface that should be easy for new users to pick up.
