Let's start at the very beginning...a very good place to start
On Friday we learned about how the cameras are built and how the darkroom works.
The cameras are a lightproof box with a tiny hole in one of the sides. This hole allows only one ray of light through, o only ray of light reflecting each particle/place in the object you're photography enters, creating a projection of the object on your film. We can then develop this.
The darkroom is also lightproof. We have paper around the door to make sure no light enters while we're developing, but to see, we have a red light which won't ruin the black and white photos. To develop, we first put it in a solution of developer, a base. Once the picture is developed enough, we put it in a solution of acid to neutralize the base. After that, the photo must be set in another solution to keep the colors there- without this, the colors would fade over time. Then the photo must be rinsed in water that is continuously cycling to keep the water fresh. The actual developing process takes four minutes at the most and the rinse takes about 15-30 minutes.
Now that we know how this works, we'll hopefully be able to start making our cameras soon. :)
