Hello I found this camera when I moved houses nine years ago and just fully started looking at it (putting batteries and trying the film that was left over with it.) it had an expired roll of Kodak t400CN and when I look it up all I can find is expired packs of it not sure what to do or if there’s film I could substitute. Help pls!
I know how to load it and everything I just need to buy non-expired film and am I looking it up wrong???
