So you have a camera that requires film to capture the image. How does it go from your camera to a picture sheet?

I don’t really know about color, but for black and white

You got this crazy goo on some paper that just changes when light hits it. The more light that hits it, the more it changes. The more it changes the more it holds onto the paper. After you take your picture, the paper has different spots of lots of changed goo and very little changes goo, so we wash away the goo that hasn’t changed, leaving a more hardened goo where the light hit. If you look at the paper (which you can kinda see where the old goo washed off because it’s kinda see through) you see dark spots where lots of light hit and see through spots where light didn’t hit so much. But its all backwards! That’s okay. Take the kinda see through paper now and put a light behind it. The light goes through the see through parts and the darker parts where the new crust goo formed cast shadows. If you lift the light and the funny paper, you cast a really big shadow. Now get some special paper that you can only open in your special room with its special lights and you can put the special paper in the “shadow” you just made. Mess around with how much time to leave the light on to cast the shadow, and now, your special paper has changed. Where there was light, the paper will get darker. Where there was shadow, the paper will at white. BUT you can’t see anything… yet. Put the paper through some nasty smelling trays and you will actually be able to watch your new picture appear on the page.
