I'm new to APUG and relatively new to 35mm colour film photography so please excuse if this is a stupid question to ask and/or in the wrong forum xD

I am interested in purchasing a film scanner but wondering what the process is for scanning the negatives? how do you get the negatives in the first place?
Does the film canister have to be taken to a shop and be processed? Or can you do it all at home with the film scanner?

I sent an email to a company and they said you could do it straight from the camera to printer but I want to clarify this because I was lead to believe film is light sensitive- thats how it works right.

Thanks,
Bella
