Thanks. I believe that the word 'negative' is being used to describe the strips or sheets of transparent plastic that you got when taking photos with a film camera. A reverse image used to delope the print. Does that help?

Yes, I know what negative is. I worked with photographic films in my youth. I have to understand how this translates into this challenge. I think you interpreted correctly.

Thanks! I thought it might be a language translation issue. I'm happy that you think I did it correctly.

Yes, with pleasure!
