When we finally had all the components together and tried the sensors and the moving mechanism inside our camera body, we got extremely low values from the sensors. So low, in fact, that we need to make some significant changes to the camera. A few of the the things we are considering as our next steps are:

Working with photodiodes instead of photoresistors

Changing our base resistors

Increasing our pinhole size

Removing the vellum

Using a lense

Altering the software to simulate the additive nature of film

Re-creating another, 3rd, sensor head - ours has four damaged cells

Or, some combination thereof.
