What's the advantage of this, though?
Well, as you know, many folks spend big bucks on attempting to simulate the look of films, whether by software, or by cameras which purport to achieve a look similar to that of film.
They miss the point in a way, because there is more than just the aesthetic, there is also the process which begins with a film choice though visualisation and photography, then to final printing whether by traditional or digital means.
A new roll of film, loaded with a particular subject set in mind, fresh and hopefully not degraded by dust or temperature variation works better for me at least, than taking my Fuji X-T3 and wandering around trying to make up my mind for each shot which sim to use, or even worse, shooting raw and then fiddling around in post trying to fit a simulation to an image.
A new roll of film locks everything in, the base film characteristics, the colour temperature, the speed - and it's a nice clean canvas upon which to imprint an image.
I guess a painter feels the same way, when preparing a new canvas set upon an easel.
