how does a photo negative get resized?

187 viewsOther

I looked up the process for developing pictures yourself, and I’m confused on what part of the process takes the negative from the roll, which is like what, an inch or so, and then enlarges it to become a 4×6 picture.

So how does it happen? What part of the developing process makes this happen?

Nothing!  “Developing” the films just means making the film non-reactive to any light exposure

Once the film is developed you would need some kind of scanner printer to make the 4×6 photos 

Before digital conversion they used an enlarger (think overhead projector) and special reactive paper and another set of chemicsls
