how does a photo negative get resized?

189 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?

You take the negative and put it in front of a light, which then projects the image onto a piece of paper, which you can then treat with photoreactive chemicals to get the positive image in the right colors. That projection allows you to size the image to basically any size you want.
