I used some Vision2 500t (unknown age and storage) for existing light shooting at night, and I was surprised at how well it handled any kind of light you could give it. I used regular c-41 processing and took the rem jet off at the end(messy!).
If I were to go to a museum or even a concert, this would be a film to use.
My daughter actually used it at a rock show and got a couple good shots. If she remembered to stop jumping up and down when she shot them, there would have been more keepers.
