That sounds like a good ideia, I'll end up losing a roll but at least I'll have some ideia of what it looks like. Even in the casa of throwing those rolls in the bin I'm probably gonna open them up for curiosity.
For anyone wandering, I live in Brazil and things here are a lot different when it comes to supply; film is expensive here. A roll of Kodak Colourplus 200, which is the cheapest still in production film I've found, cost around 5,8 u$. And that's a cheap consumer grade film. Tri-X cost around 14 u$. So I'm always looking for cheap film, I've recently found I guy who sells very cheap movie films reloaded in 35mm cannister. I'm very interest but afraid because of the Rem-Jet and further difficulties in processing the film (would have to be in C-41, good luck trying to find someone in Brazil with the chemistry for the original movie film process).
When it comes to lab, it's very limited. I live in a capital altough is not one of the huge ones (São Paulo and Rio), so I'm pretty much stuck with C-41 minilabs. I've been trying to contact a professional photographer that has an actual darkroom and see if he could give me some classes on it.
I'm shooting film mainly for the novelty it represents to me, and I've been reading a lot about develpoment and printing darkroom process. Haven't been able to actually develop a film myself; the only film developing tank I've found in Brazil is being sold for 90 u$ (That's just stupid) so I've been holding off on buying the supplies until something better comes off. " Fortunately " developing C-41 in minilabs is pretty cheap, you can get it as cheap as around 2-3 u$ a roll.
