I just decided to try out making a pinhole polaroid and i have a question about polaroid film. It seems that the way I made mine the film will only eject if i take out the film and put it back in, like when you put in a fresh pack and the black card gets ejected, same thing happens with the film. However when I take the film out will all the other film be exposed and ruined? I dont feel like spending 25 dollars to find out maybe someone knows. Any help would be wonderful, thanks.
