Question: What is the correct size? Someone mentioned in an earlier post that all I need to do is double the width. Is this correct? If so, please explain further, as I'd like to know!
Double-the-width seems to work for 16mm/Scope film. I don't know what the right correction would be for your capture, though... if it's a capture of a 35mm film, I would expect the correction could be different.
