So you have a camera that requires film to capture the image. How does it go from your camera to a picture sheet?
In: 1
Few steps:
1. You wind up your film inside the camera so it’s in a light tight spool, you take that out of the camera.
2. You go into a black room (zero light including red). You have to take out the film from it’s canister, thread it on a ring/spool that spaces it out so no layers touch, put it in a light tight container that has some holes in it.
3. Soak said container in various chemicals that set the film so you can take it out in the light.
4. Acquire dark room (red light)
5. Do you know the old school overhead projectors? You’d have a transparent sheet with words in it that you’d project on a screen. Developing pictures is like that but small. The light is projected through the film and down on to light sensitive paper. Based on the amount of light that gets through the film that darkens the paper to create the same image. If it’s projected closer to the paper the photo is smaller, further away to be bigger. There’s more technical stuff about focus and whatnot, but that’s the gist of it.
6. Then the light sensitive paper needs to be soaked in various chemicals and dried so that it sets and can be taken into the light.
That’s the old school manual process for it, they do have machines that do that too.
