Old cameras recorded in black and white. Did people in the 20s live in B&W? Or maybe the camera is a device that attempts to record a picture of reality at some point in space-time, with lossy compression, to match the perceptions of reality of its creators? The thing is, you can have a consistent model of reality when you're only looking at it from the inside. This tells you nothing about the outside. Eg: if you're living in a simulated universe, everything is consistent, your cameras and the dry desert. Still, outside the thing you perceive as reality, there could be anything.
